Alternative medicine: Apple

The many health benefits attributed to apples have given rise to the ancient saying that eating an apple a day keeps the doctor away. Botanical: Pyrus malus Family: N.O. Pomaceae Synonym: Wild Apple.

Malus communis. Habitat: The temperate regions of the Northern Hemisphere.

Description: The 5 to 12 meter tall apple tree is deciduous. Its simple oval leaves are alternately arranged with acute tips. The flowers are white with a pink tinge which gradually fades. The centre of the fruit contains five carpels arranged in a five-point star.

Part Used Medicinally: The fruit and the bark. Constituents: Apple has 80 to 85 percent water, 5 percent proteid, 10 to 15 percent starch and sugar, and 1 to 1.5 percent acids and salts. All apples contain varying amount of the organic malic and gallic acids, vitamins A and C, pectin and iron.

Medicinal Uses: Fresh apple is rich in vitamins, and is used to treat scurvy. Apple is sedative and tonic. It is used to treat diabetes and lower the blood cholesterol.

It also has antiseptic and anti-rheumatismal effects and may help with heart disease, and weight loss. Apple's high content of vitamin C as well as other antioxidant compounds reduces the risk of colon, prostate and lung cancers.

Its fiber content helps regulate bowel movements. A group of chemicals in apples protect the brain from damages triggering neurodegenerative diseases such as Alzheimer's and Parkinsonism. Apple consumption can act as an excellent dentifrice. It also pushes back the gums so that the borders are cleared of deposit. It's malic and tartaric acid content helps individuals with liver disorders.

Apple acids not only make the fruit itself digestible, but also help with the digestion of other foods. Its sugar is predigested and enters the blood rapidly to provide the body with energy and warmth. Apple juice, without sugar, reduces the stomach acidity and corrects sour fermentation. Consuming ripe, sour, juicy apples at bedtime cure constipation and some cases of insomnia. Regular apple consumption prolongs life span.

The glucoside extracted from apple bark and root, is effective in treating diabetes. Apple bark decoction is used to treat intermittent fevers. Cooked apples make a good homemade remedy for sore throats, fevers, eyes inflammation and erysipelas. Apple consumption appears to promote hair growth. It may also delay aging and skin wrinkles. A polyphenol compound extracted from unripe apples has an inhibitory dose-dependent effect against cholera toxin and can treat diarrhea.

Apple is a rich source of flavonoid and can improve lung function in asthmatics and lower the incidence of coughing and breathlessness in COPD patients. It may also prevent the development of carcinogenic substances in the bladder, lung and prostate. Consuming apples is related to a decreased risk of thrombotic stroke and heart attack mortality.

Apples play an important role in reducing the risk of a wide variety of chronic disease and maintaining a healthy lifestyle in general. In India, physicians prescribe apple cider vinegar in combination with the herb Gotu Kola to help revitalize the skin. When mixed with honey it improves digestion.

It is antibacterial and anti-fungal and boosts the immune system. It also fights respiratory infections, sore throats and nasal discharges. Apple cider vinegar is good in individuals suffering from arthritis because it breaks down calcium deposits in the joints while remineralizing the bones. Apple cider vinegar is a good remedy for food poisoning, urinary tract infections and lowering high blood pressure.

It is also a good source of potassium for diuretic users. preparation Eating 2 to 3 unpeeled red apples 3 times a day, is an effective treatment for diarrhea. Consuming unpeeled yellow apples before sleeping or in the morning is a good remedy for constipation. Eating 1 or 2 yellow apples after each meal will also lower the blood sugar and cholesterol levels. Eating green apples helps the liver function.

Caution Eating too many apples especially when cooked may cause amnesia. The fruit's malic acid erodes tooth enamel over time. The seeds, which contain small amounts of amygdaline, a cyanogenic glycoside, are mildly poisonous, but only chewing a large amount can cause toxic effects.

Alternative medicine: Tomato

Tomatoes are not only heart healthy but can also fight several types of cancer and help develop healthy teeth, bones, skin and hair.

Botanical: Lycopersicon lycopersicum Family: N.O. Solanaceae Synonyms: Lycopersicon, pomme d'amour, pomodoro Habitat: The tomato which originated from the highlands of the west coast of South America is now available all over the world.

Description: Tomatoes are perennial vines, typically reaching 1-3m in height. The fruit botanically classified as a berry has fleshy internal segments filled with seeds and a watery matrix.

The tomato's predominant colors are red, yellow and green; however, purple and brown ones are also produced. They range in size from small cherry tomatoes to medium plum/roma tomatoes to large slicing/beefsteak tomatoes.

Part Used Medicinally: Fruit Constituents: Tomatoes are an excellent source of vitamin C and other vitamins like A, B1, B2, B6, E, K and niacin. They are rich in molybdenum, potassium, magnesium, iron, folate, copper, phosphorous, manganese, dietary fiber and chromium.

In addition, tomatoes contain small amounts of nicotine (coumaric and chlorogenic acid). Containing only 20 calories, they are a good source of phytochemical lycopene, beta-carotene and several other carotenoids.

Medicinal Uses: Tomatoes are rich in antioxidants which play a key role in maintaining a healthy immune system and fighting against infection. Due to their high content of lycopene (a powerful anti-oxidant) and phytonutrients, tomatoes lower the risk of prostate, colorectal, pancreatic and stomach cancers.

The consumption of tomatoes with fat-rich avocado, nuts and olive oil increases the fruits anti-cancer properties. Eating tomatoes and broccoli together has shown better results against prostate cancer. Two powerful compounds found in tomatoes, coumaric acid and chlorogenic acid, are thought to block the effects of nitrosamines, thus reducing the risk of lung cancer.

The tomato's high antioxidant content prevents from inflammation and the progression or severity of atherosclerosis, diabetic complications and asthma. The tomato's high potassium content makes it an effective stroke preventer and lowers blood pressure.

The vitamin K found in tomatoes helps maintain healthy bones by activating osteocalcin, a protein which anchors calcium inside the bones. It also helps prevent hemorrhages. Tomatoes are acidic, so they may upset the stomach in individuals with gastrointestinal discomfort.

Individuals with high cholesterol levels, those whose work involves traveling long distances, those who have recently undergone a surgical procedure and smokers benefit from this fruit. The blood thinning effects of tomato juice are noteworthy for individuals at higher risk of blood clot formation. A tomato-rich diet helps improve skin texture and color. Tomatoes help in liver congestion (cirrhosis) and gallstones.

The nicotinic acid in tomato can help reduce blood cholesterol and prevent heart diseases. A high dietary intake of tomato products helps lower LDL and cholesterol levels. Its high chromium content helps control blood sugar in diabetics and reduces the risk of developing cardiovascular disease in type 2 diabetics. Tomatoes are heart-healthy because their vitamin B6 and folates are needed to help the body convert homocysteine, a potentially dangerous chemical, into other benign molecules.

High levels of homocysteine can damage blood vessel walls and increase the risk of heart attack and stroke. Tomatoes can also fight chronic degenerative ailments such as atherosclerosis, osteoporosis and Alzheimer's disease.

Tomatoes are a good source of riboflavin, which helps reduce the frequency of migraine attacks. Preparation: Using a whole tomato is more recommended as it contains more lycopene. Bright red tomatoes have the highest amounts of beta-carotene and lycopene. Cooking tomatoes in oil especially olive oil helps the body absorb more lycopene.

It is important not to cook tomatoes in aluminum cookware since their high acid content will interact with the metal causing deleterious health effects. It should be noted that cooking and canning do not reduce the nutritional value of tomatoes.

Concentrated tomato products such as tomato paste are recommended over whole fresh tomatoes as they deliver more carotenoids and protect the skin against the damaging effects of the sun.

Caution: The tomato plant's leaves contain toxic alkaloids. Tomatoes are one of the foods most commonly associated with allergic reactions including eczema, hives, skin rash, headache, runny nose, itchy eyes, wheezing, gastrointestinal disturbances, depression, hyperactivity and insomnia. Individuals who suspect food allergy to be an underlying factor in their health problems should not use this fruit.

Tomato gel better than aspirin?

A natural ingredient found in tomato seeds can help maintain a healthy blood circulation by preventing blood from clotting, new clinical trials have found.

Discovered in 1999 by Professor Asim Dutta-Roy, the tomato-based ingredient, derived from the gel around tomato seeds, can improve blood flow.

The colorless and tasteless gel prevents the clumping of blood platelets, reducing the risk of clot formation, in a similar way to aspirin but with no side effects.

Patented as “Fruitflow”, the gel is believed to act by targeting several platelet aggregation pathways rather than just one.

The onset of the effects is within three hours of its consumption and may last for some 18 hours, making it ideal for daily consumption, the British researchers reported. Scientists suggested that adding the gel to certain foods can overcome the need for daily aspirin for warding off the risk of cardiovascular events.

Cholesterol Vital for Human Existence

"Cholesterol-free" sign can be found even on vegetable oil labels these days. Yet, vegetable oil simply cannot contain any cholesterol since the latter can be found in animal products only. We will forgive manufactures this advertisement trick and will try to find out whether cholesterol is indeed as scary as it is portrayed.

High cholesterol level is on the top of the list among the risk factors causing fatal diseases linked to atherosclerosis. It outruns any other risk factor, including high blood pressure, smoking, obesity and diabetes.

On the other hand, cholesterol is a required component contained in most of the tissue. It is vital for human existence. Cholesterol aids in building new cells, hormone production, and creation of intercellular membranes isolating internal organs from negative environment; helps to digest vitamins and accumulate energy.

Yet, cholesterol is only good for you until its level exceeds safe limits. As soon as it exceeds the mark of 200–250 mg/dL, it turns from a helper into an enemy.

Cholesterol comes from food and penetrates the blood where it transforms into serum cholesterol which can be good or bad. Good cholesterol is composed of high-density lipoprotein (HDL). HDL cleans the arteries. Bad cholesterol is composed of low-density lipoprotein (LDL) that clogs the vascular walls with atherosclerosis plaques.

High-density lipoprotein comes from monounsaturated fats contained in nuts, legumes and corn, and polyunsaturated fatty acids contained in vegetable oils, fowl, and fish.
Bad cholesterol comes from butter, meat, egg yolks, and milk.

Exercise is an important part of preventing high cholesterol levels. Regular physical activity can help to reduce dangerously high levels, especially if it is accompanied by quitting smoking. Dietary supplements that are effective in preventing atherosclerosis contain nicotinic acid, vitamins C and E, and calcium.

Unfortunately, diet and exercise are only effective if cholesterol level insignificantly exceeds the norm. If cholesterol level is higher than the norm by 25% or more, only medication will help.
It is not enough to measure the level of cholesterol in the blood to find out if it is within the safe limits.

Significant atherosclerosis is possible with low cholesterol levels, while insignificant atherosclerosis is possible with high levels. It all depends on a proportion of high-density and low density lipoprotein determined through a separate test. Ideally, LDL level should be relatively high (no less than 35 mg/dL, ideally – 65–70 mg/dL), and HDL level should be low (less than 130 mg/dL), while the total amount of serum cholesterol should not exceed 200 mg/dL.

Human body produces on average 1 gram of cholesterol per day. The largest amount (800 mg) is synthesized in the liver, 200 mg is produced by the rest of the cells, and 500 mg comes with food.

According to WHO, the recommended dose of cholesterol for healthy people should be no less than 300 mg per day, while people with high cholesterol levels and those suffering from cardio vascular diseases should consume less than 200 mg per day.

Diet 'more effective' than drugs in delaying diabetes

Compared to taking anti-diabetes drugs, adopting a healthy diet and regular exercise are more effective in staving off diabetes for a decade, a new study finds.

According to the study published in The Lancet, lifestyle changes resulting in small but long-term weight loss is twice as effective as drug treatment for preventing type 2 diabetes. Following a healthy diet combined with a half an hour of exercise five days a week reduces the risk of developing Type 2 diabetes by 58 percent.

Taking metformin -- a drug commonly used to treat diabetes, conversely, lowers the risk of the condition by nearly one-third. While lifestyle intervention postpones the onset of diabetes by four years, the delay time would be about two years in those taking medication.

The benefits of intensive lifestyle intervention were reported to be stronger among the elderly. "There seems to be no short cut, and a persistent and prolonged intensive lifestyle intervention seems to be the most effective way to travel on it," said Anoop Misra, a specialist in diabetes in New Delhi.

Despite the fact that lifestyle and metformin are both useful for delaying or preventing diabetes, scientists concluded that dieting is more effective than medication.

Diet sodas cause kidney problems: Study

While diet sodas are gaining more popularity among individuals worried about their calorie intake, a new study finds these drinks are linked to kidney problems.

According to the study presented at the annual meeting of the American Society of Nephrology in San Diego, drinking two or more diet sodas per day doubles the risk of developing impaired kidney function.

A 30 percent drop was reported in the glomerular filtration rate (GFR), an index determining the function of the kidneys, of women who drank two or more artificially sweetened sodas per day.

"Thirty percent is considered significant,'' said lead researcher Julie Lin, adding that natural aging is associated with only 1 mL per minute per year decline in GFR. Drinking less than two sodas a day, however, does not affect kidney function in these women.

Scientists added that high salt intake is also associated with a faster decline in kidney function.

Low cholesterol levels predict cancer

While many believe low levels of total cholesterol protects against heart attack and stroke, a new study finds it to be a warning sign for certain types of cancer.

According to the study published in Cancer Epidemiology, Biomarkers & Prevention, certain types of cancer may cause low total cholesterol levels, a combination of both the bad low-density lipoprotein (LDL) and the good high-density lipoprotein (HDL), in many individuals.

"Our study affirms that lower total cholesterol may be caused by undiagnosed cancer," said lead researcher Demetrius Albanes, stressing that high levels of good cholesterol have a protective role against all cancers, particularly among women.

Men with total cholesterol levels lower than 230 milligrams/deciliter were reported to be at an overall 18 percent higher risk of developing cancer - mainly invasive forms of prostate cancer. Scientists concluded that low total cholesterol is a sign of cancer rather than a cause.

Dieting on processed food ups risk of depression

While eating a diet high in processed foods increases the risk of depression, following a diet rich in fruit and fish can keep the condition at bay.

Previous studies had found that adopting a Mediterranean diet helps lower the risk of developing depression. In today's world, however, individuals consume less nutritious and fresh products than saturated fats and sugars.

According to a study published in the British Journal of Psychiatry, eating processed foods filled with chemicals, refined grains and sugars, processed meats, and high-fat dairy products places an individual at a 58 percent higher risk of depression.

On the other hand, eating whole foods including fruits, vegetables and fish lowers the risk of depression by 26 percent. It also improves memory, mood, and overall health.

They added that the fact that depressed individuals are less likely to adopt a healthy diet strengthens the credibility of the findings of their study.

Muscle strength influences Alzheimer's risk

Compared to their weaker counterparts, seniors with strong muscles are less likely to be diagnosed with Alzheimer's disease, a new study finds.

Previous studies had considered weight, educational level and the amount of physical activity as important factors influencing an individual's mental function.

According to the study published in the Annals of Neurology, greater muscular strength is associated with slower decline in mental abilities over time, indicating that a single mechanism in the body is responsible for both muscle weakness and memory loss.

Compared to arm and leg strength, the power of grip and breathing-muscles was found to have greater impact on mental ability. "These findings support the link between physical health and cognition in aging and the importance of maintaining good physical function and strength," said lead researcher Patricia Boyle.

Scientists therefore urged individuals to be physically active and to keep their muscle strong in order to tackle the debilitating Alzheimer's disease. PKH/HGH

Study finds fruit-rich diet prevents asthma

A study suggests that eating a fruit-rich diet could help protect children from respiratory allergies and asthma. UK, Greek and Spanish researchers assessed the diet and health of almost 700 children living in rural areas of Crete, where such conditions are rare.

The research found 80% of the children ate fresh fruit, and over two-thirds of them fresh vegetables, at least twice a day.

Eating oranges, apples, tomatoes and grapes each day, which around 300 children did, was shown to have a protective effect against wheezing and allergic rhinitis. Children who ate nuts - a rich source of vitamin E - at least three times a week, again just over 300, were less likely to wheeze.

However, high consumption of margarine more than once a week (331 children) doubled the chances of asthma and allergic rhinitis, compared with those who ate it less frequently, the findings showed. Some 5 to 10 percent of children suffer from asthma in different parts of the world.

Mediterranean diet increases life span

Scientists at the University of Cambridge claim that following the Mediterranean dietary pattern increases the life span of Americans.

According to the study published in the Archives of Internal Medicine, individuals with diets closer to the Mediterranean are 21 percent less likely to have a five year mortality rate.

Findings show that the beneficial effects of the diet include reduced mortality risk secondary to cardiovascular disease and cancer.

The study shows by closely following the Mediterranean diet smokers who are not overweight halve their risk of death. In addition, smokers strongly benefit from the antioxidant and blood fat-lowering effects of the Mediterranean-style eating.

The Mediterranean diet which consists of large amounts of fruit and vegetables, seafood, grain and olive, is low in dairy food and red meat.

Mediterranean diet lowers diabetes risk

Spanish scientists suggest a traditional Mediterranean diet can help protect individuals against type 2 diabetes and its complications.

According to a study published in the British Medical Journal, following the Mediterranean diet reduces the risk of developing diabetes by 83 percent.

Findings revealed a high intake of fiber and vegetable fat along with a low intake of trans-fatty acids not only reduced the risk of cardiovascular disease but also had a protective role against diabetes.

University of Navarra researchers claimed that using virgin oil for cooking, frying, spreading on bread and as salad dressing had an important role in the diets beneficial effects.

Olive oil has positive impacts on blood glucose control and inflammation reduction. The Mediterranean diet is rich in olive oil, grains, fruits, nuts, vegetables, and fish, but low in meat, dairy products and alcohol.

Low-salt diet can tackle hypertension

A new study shows that including too much salt in the daily regimen may contribute to high blood pressure resistant to treatment.

According to the study presented at the American Heart Association's Fall Conference, adopting a high-salt diet leads to high blood pressure which remains above goal levels despite taking three anti-hypertension medications.

The study showed that adopting a low-salt diet is associated with a considerable drop in both systolic and diastolic blood pressures.

Findings revealed that salt restriction effectively lowers blood pressure by reducing intravascular fluid retention and improving vascular function.

Scientists concluded that patients who despite taking multiple blood pressure-lowering drugs continue to suffer from an uncontrolled high blood pressure can lower their BP by adopting a low-salt diet.

Western diet ups heart attack risk

A recent US study has revealed that the typical western diet is responsible for a considerable number of heart attacks in the world.

According to the study published in Circulation: Journal of the American Heart Association, following a western diet rich in fat, salt and meat accounts for about 35 percent of heart attacks.

The study reported that a salt-rich diet places individuals at a greater risk of developing cardiovascular events by increasing blood pressure and harmful lipid levels.

Findings revealed that an Oriental diet which is high in tofu and salty soy sauce does not influence the risk of developing heart problems.

Scientists concluded that regardless of which region one resides in, the higher the regular intake of fried and salty foods is, the greater the risk of heart attack.

They urged individuals to adopt a healthy diet high in fruit and vegetables to reduce the global heart attack risk.

Mediterranean diet improves diabetes management

While the Mediterranean diet had long been linked to greater weight loss, a new study finds this diet more efficient in controlling blood sugar.

According to the study published in the Annals of Internal Medicine, a low-carbohydrate, Mediterranean-style diet is more effective in diabetes management compared to typical low-fat, calorie-restricted diets.

Following a Mediterranean diet with at least 30% of daily calories from fat (mostly olive oil) delays the need for taking diabetes medication and improves certain heart disease risk factors.

The Mediterranean diet -- rich in fruits, vegetables and whole grains, and low in red meat and processed foods -- also resulted in trimmer waistlines and increased the "good" HDL-cholesterol levels, all of which are considered to be heart-healthy changes in the body.

Scientists concluded that reducing the need for diabetes treatment should also be added to the Mediterranean diet's long list of health benefits including greater longevity.

Night-time eating ups obesity risk

Excessive late-night eating and midnight raids on the refrigerator are linked to increased weight gain and worse health consequences, a new study finds.

Recent studies have reported that circadian rhythms -- the body's internal clock -- have a critical role in how the body spends energy.

According to the study published in the International Journal of Obesity, late-night snackers are more likely to gain weight, adding that mice eating at unusual hours put on twice as much weight, despite exercising and eating as much as others.

Night-fed mice are reported to weight 7.8 percent more than those fed during the day. "Better timing of meals could be a critical element in slowing the ever-increasing incidence of obesity," scientists concluded, claiming that simply changing the timing of meals and snacks can considerably help reduce weight.

Scientists concluded that night-time eating is one factor among many others contributing to weight gain.

Larger thighs may add to longevity: Study

Individuals with narrow thighs are believed to die sooner than their counterparts who have larger thigh circumference, a new study finds.

Previous studies had reported that obesity is the strongest risk factor affecting one's health, adding that waist size (abdominal obesity) is a good predictor of heart disease, diabetes and early death. According to the study published in the British Medical Journal, thigh size is an accurate marker of longevity and narrower thighs increase the risk of premature death.

Individuals whose thighs are less than 60 centimeters in circumference are at a greater risk of premature death. The risk is reported to be doubled in those with the thighs less than 55 centimeters. "Additionally we found that the risk was more highly related to thigh circumference than to waist circumference," said lead researcher Professor Berit Heitmann, adding that the results are similar for both sexes.

Those with narrower thighs lack the muscle mass necessary to ensure proper glucose and lipid metabolism, a condition leading to type 2 diabetes and, in the long-run, heart disease. Scientists believe thigh size could soon be used as a marker for identifying patients at-risk of early death or other serious health problems.

Genes link gum disease to heart attacks

Researchers have discovered a genetic link between a certain type of dental disease and the increased risk of strokes and heart attacks.

Previous studies had revealed the high frequency of heart events, pancreatic cancer and the reactivation of latent HIV-1 among individuals suffering from periodontitis --a gum disease that results in loss of connective tissue and the bone supporting the teeth.

The main reason linking coronary heart disease (CHD) to the gum disease, however, remains unclear. According to a study presented at the annual conference of the European Society of Human Genetics, a genetic locus on chromosome 9 is responsible for the higher risk of CHD among patients with periodontitis. CHD and periodontitis are both characterized by an imbalanced immune reaction and chronic inflammation.

Both diseases, furthermore, have similar risk factors including smoking, diabetes and obesity. The bacteria found in the oral cavity are akin to those in coronary plaques, indicating that the bacteria involved in gum disease is a possible trigger for low grade inflammatory responses and changes in the arteries leading to cardiovascular events.

Scientists urged individuals with periodontitis to reduce their risk factors and take preventive measures at early stage to prevent possible heart events. They also recommended the dentists to take gum disease seriously and diagnose and treat it as early as possible with the aim of preventing further heart-related complications.

Gum disease increases cancer 'risk'

A new study warns that chronic gum disease, which had long been linked to heart attack and stroke, is a risk factor for cancers of the head and neck.

According to the study published in Cancer Epidemiology, Biomarkers, and Prevention, chronic periodontitis, an advanced gum disease determined by progressive loss of bone and soft tissue that surround the teeth, is associated with increased risk of head and neck tumors.

Periodontitis significantly increases the risk of head and neck cancer even in subjects who had never used tobacco and alcohol. With each millimeter of alveolar bone loss, the risk of developing head and neck cancer is reported to increase by more than 4-fold.

Scientists believe that their findings explain the reason for which the rate of head and neck cancer continues to climb despite the considerable decline in smoking rates in the past 40 years.

Drinking tea strengthens bones

Drinking tea not only refreshes your mind but also this ancient drink has beneficial effects on bones, a new study has disclosed.

The Australian study published in the American Journal of Clinical Nutrition, revealed tea may help preserve the hip structure in elderly women.

The findings showed that bone mineral density is 2.8% higher in tea drinkers. In addition, during a 4-year period the tea drinkers lost an average of 1.6% of total hip density compared to 4.0% in non-tea drinkers.

Previous studies had also shown that drinking tea was associated with a higher bone mineral density and a reduced risk of hip fracture. Bone mineral density is the second most important risk factor for hip fractures apart from aging.

Lifestyle factors, including dietary intake of calcium, protein, and sodium, affect bone density and the risk for hip fractures.

Green tea tackles colorectal cancer

A recent animal study suggests that polyphenon E, a compound found in green tea extract limits the growth of colorectal tumors in rats.

According to results presented at the Sixth International Conference on Frontiers in Cancer Prevention, rats on a diet containing polyphenon E are less likely to develop colon cancer. The study shows polyphenon E decreases the number of malignant tumors per rat and the tumor size.

Findings reveal 67 percent of the rats on a normal diet developed malignant tumors while in the treated group the risk was about 27 percent.

In addition, tea polyphenols decreased the tumors per rat by 80 percent compared to the control group.

It should be noted that at the same conference, black raspberry gel and 'Blueberry Punch' (an antioxidant-boosted beverage) were reported to be effective in treating oral cancer lesions and prostate cancer.

Green tea lowers prostate cancer risk

Japanese scientists suggest drinking daily five or more cups of green tea could halve the risk of developing advanced prostate cancer.

According to the article published in the American Journal of Epidemiology, there was a 50 percent lower risk of having advanced prostate cancer in men who drank five or more cups of green tea daily compared with those who had less than a cup.

Findings show while drinking green tea lowers the risk of advanced prostate cancer; it is not associated with localized prostate cancer.

Researchers claim that a substance called catechin in green tea is responsible for reducing cancer risk by curbing testosterone levels which cause prostate cancer.

The study suggests that the lower incidence of prostate cancer in Asians may be linked to the higher consumption of green tea.

Previous studies had reported various health benefits for the green tea catechin including reduced cancer and heart attack risks.

Scientists say exercise strengthens brain

Scientists say exercise boosts brainpower by building new brain cells in a brain region linked with memory and memory loss.

Researchers have conducted tests on mice and found out exercise affects a part of the brain called dentate gyrus, which is responsible for age-related memory loss.

Later they used magnetic resonance images to figure out the effect of exercise on human. They found similar patterns in human. "Once these findings were established in mice, we were interested in determining how exercise affects the hippocampal cerebral blood volume maps of humans," they wrote.

They, however, could not dissect the brains of people to see if new neurons grew, but they could use MRI to have a peek.

Exercise hastens prostate cancer growth

American researchers suggest that exercising is associated with an accelerated tumor growth rate compared to a sedentary lifestyle.

According to a study presented at the annual meeting of the American Association for Cancer Research in San Diego, cancerous cells in active mice multiply twice as quickly as in their peers who do not exercise.

Findings showed that exercise speeds up the tumor growth by increasing the blood flow of the prostate gland. Duke University Medical Center scientists recommend prostate cancer patients to continue exercising despite the findings of the present study.

They maintain although exercise may promote tumor growth, it reduces the risk of developing heart disease, diabetes and obesity which are the leading causes of several life-threatening complications.

Exercise ups anemia risk in young men

While exercise is believed to be good for health, a new study finds that strenuous physical activity places young men at an increased risk of iron deficiency.

According to the study published in the Journal of Adolescent Health, intense physical activity increases the risk of developing anemia (low blood count) as well as iron deficiency in young men.

An intense six-month training program is reported to not only triple the risk of anemia to over 50 percent but also to double the risk of iron deficiency from about 15 to 27 percent.

"Iron deficiency and anemia are generally uncommon findings in healthy male adolescents. However, athletes who engage in strenuous physical activity are known to be at increased risk for so-called 'sports anemia," reported scientists.

Researchers believe drinking sufficient amounts of water is the main reason, which may contribute to the condition through temporarily diluting the blood and subsequently damaging blood cells.

High margarine intake ups bowel disease

While many believe adopting a diet rich in polyunsaturated fat is heart tonic, a new study finds it may lead to inflammatory bowel disease.

Ulcerative colitis, an inflammatory bowel disease, causes inflammation and ulcers in the lining of the rectum and colon. The condition is characterized by abdominal pain and diarrhea.

According to the study published in Gut (International Journal of Gastroenterology and Hepatology), the high intake of linoleic acid -- a common dietary polyunsaturated fatty acid found in many dietary sources such as red meat, various cooking oils (sunflower, safflower, soya, corn seeds and walnut oils) and some types of margarine -- accounts for one-third of ulcerative colitis cases.

The high content of the omega 3 fatty acid known as docosahexanoic acid found in oily fish such as salmon and herring, on the other hand, lowers the risk of the condition by 77 percent. Linoleic acid converts to arachidonic acid and various other inflammatory chemicals, high levels of which are found in the bowel tissue of patients with ulcerative colitis.

"There are no dietary modifications of benefit in patients with ulcerative colitis, although, based on this study's findings, a diet low in linoleic acid may merit investigation," concluded lead researcher Andrew Hart.

Physically-abused moms spank their infants

Mothers who have suffered from physical abuse or other forms of violence during childhood are more likely to spank their infants, a new study finds.

Previous studies had reported that spanking is associated with an increased risk of behavioral problems, low self-esteem, depression, drug abuse and physical abuse.

A new study, however, reported that many mothers still continue to spank their children. According to the study published in Pediatrics, mothers who had suffered childhood abuse spanked their children more than those without such experiences.

The study showed that some 19 percent of mothers consider physical punishment as a disciplinary means and 14 percent actually spank their infants.

One in every ten mother who had no experience of childhood violence also reported infant spanking. Scientists concluded that a mother's childhood experiences influence her behavior toward her children.

They, therefore, urge healthcare professionals to ask pregnant moms about family structure and childhood experiences to prevent such events.

Heavy drinking increases prostate cancer risk

Regular, heavy consumption of alcohol increases the risk of high-grade prostate cancer and reduces the effect of drugs used to tackle the condition.

Previous studies had reported older age, African-American race, family history of prostate malignancies, obesity, smoking and a high intake of animal fat to be the major risk factors contributing to prostate cancer.

A new study, however, reported that heavy drinking is also linked to prostate cancer. According to a study published in Cancer, men who drink four or more drinks per day at least five days a week are twice as likely to developing aggressive prostate tumors.

Finasteride, a medication which lowers the risk of prostate tumors by 43 percent, is believed to increase the risk of the condition by 12% among heavy drinkers.

Scientists therefore urge physicians to assess their patients' alcohol consumption before prescribing the drug finasteride.

They also recommended that individuals not drink more than two or three alcoholic beverages per day while taking finastride.

High-fructose diets impair memory

Adopting a diet rich in fructose, a form of sugar commonly found in processed foods and beverages, may result in impaired spatial memory.

Previous studies had reported various health problems such as insulin insensitivity, type 2 diabetes, obesity and cardiovascular disease following the use fructose, the sweetener commonly found in table sugar, fruit juice concentrates and high fructose corn syrup.

According to a study conducted in Georgia State University, high fructose intake can also impair memory in consumers.

It, however, does not influence an individual's ability to learn. Unlike glucose, high levels of triglycerides are produced during the digestion process of fructose within the liver.

This fat can subsequently interfere with the insulin signaling mechanism of the brain, affecting not only the survival of brain cells but also their ability to change based on new experiences.

Scientists concluded that the high content of fructose can impair memory.

Men at higher risk for cancer

A new study has found that men are more vulnerable to developing cancer and subsequently dying from it. Excluding breast, lung and other cancers that are gender specific, the differences between the genders are reported to be considerable.

According to a study published in Men's Health Forum, men are significantly more prone to being diagnosed with and dying from any type of cancer apart from melanoma.

Men are reported to be 60% more likely to develop cancer and 70% more likely to die from it. Scientists were unable to find any known biological reason for the higher risk of cancer among men; they, however, claimed that men are less health conscious compared to women.

"What we see from this report could be a reflection of this attitude, meaning men are less likely to make lifestyle changes that could reduce their risk of the disease and less likely to go to their doctor with cancer symptoms," said Alan White, the lead researcher of the study.

Men do not seek medical advice in the early stages of the disease; many of them also follow unhealthy lifestyles. Men are believed to be less aware of the adverse effects of smoking, having extra weight around the waist, having a high alcohol intake, a poor diet and having a positive family history for malignancies contributing to the increased risk of cancer.

Scientists therefore urge men to adopt a healthy lifestyle, adding that the majority of cancers can be prevented through lifestyle changes.

Whole carrots fight cancer better

The anti-cancer properties of carrots are reported to be more enhanced when they are cooked whole and not chopped up beforehand. Carrot has long been used in alternative medicine due to its positive effects particularly in boosting night vision.

The anti-cancer properties of carrot resulting from its high falcarinol content were discovered some four years ago. A new study, however, reported that this compound remains intact if the carrot is cooked whole.

According to the study presented at NutrEvent, a conference on nutrition and health, the "boiled-before-cut" carrots had 25 percent more falcarinol than sliced and cooked ones.

"Chopping up your carrots increases the surface area so more of the nutrients leach out into the water while they are cooked," said lead researcher Kirsten Brandt. Carrots cooked whole are also reported to be tastier as they retain their sugar in this manner.

Men suffer from mineral deficiency

The majority of men in the modern world struggle with severe deficiencies in key minerals and vitamins due to following unhealthy diets.

According to a study published in Men's Health, 77 percent of men do not take enough magnesium, the element involved in more than 300 bodily processes particularly those responsible for generating energy, in their daily diet.

The daily intake of magnesium in men is reported to be about 80 percent of the recommended 400 milligrams. Low levels of magnesium are linked to increased blood levels of C-reactive protein, a key marker for heart disease.

Scientists therefore urge men to include more magnesium-rich foods such as halibut and navy beans along with magnesium supplements in their daily diet. As for vitamin D, men are reported to suffer from vitamin D deficiency, making them more vulnerable to developing cardiovascular events such as heart attack and stroke.

Many researchers recommend the male population to take 1,400 IU of vitamin D supplements a day, indicating that this amount is seven times higher than the recommended daily dosage but is necessary to boost blood levels of vitamin D.

While men are reported to consume the daily quota of 2.4 micrograms of vitamin B12, the increased consumption of certain medications such as acid-blocking drugs and diabetes medication among this population contributes to large-scale vitamin B12 deficiency.

Vitamin B12 is necessary to protect the gray matter of the brain. Seniors with the lowest levels of B12 are reported to lose their brain volume at a faster pace over a span of 5 years compared to those with the highest levels.

While the daily diet is load up on sodium, men only use 60 to 70 percent of the recommended 4,700 mg a day of potassium, another essential dietary mineral critical for nerve impulse transmission, muscle contraction, and heart function.

Scientists urge men to take avocado (half an avocado contains nearly 500 mg of potassium) and banana (containing some 400 mg of potassium) each day, adding that potatoes (1,600 mg) are a good source of the mineral for those who do not like fruits.

Finally, iodine -- the mineral necessary for the accurate function of the thyroid gland which controls metabolism as well as weight and the feeling of exhaustion -- is not efficiently used by men.

The majority of salt tables are reported to contain lower than the FDA-recommended amounts of iodine. Scientists urge individuals to make up for the lack of the mineral with milk, eggs or yogurt.

Sunshine vitamin fights 'mental decline'

Vitamin D is reported to play a critical role in keeping the brain in a good condition and prevent mental decline in old age.

While previous studies have indicated that vitamin D can protect individuals against cancer, artery disease and tuberculosis, a new study reveals that high levels of the sunshine vitamin can ward off mental decline.

According to a study published in the Journal of Neurology Neurosurgery and Psychiatry, high levels of vitamin D slow down the ageing process in the brain, preventing dementia and memory loss commonly experienced in old age.

Elderly folk who achieve vitamin D levels higher than 35 nanomoles per liter are reported to perform better on visual scanning, memory and information processing tests.

Produced by the body when skin is exposed to sunlight, vitamin D protects cells and key signaling pathways in the brain, perking up its performance.

Scientists conclude that inadequate amounts of vitamin D in a person's regular diet can alter the mental performance in old age; they therefore urge individuals to add vitamin D supplements with the aim of tackling or preventing dementia.

Alternative medicine: Garlic

Garlic has long been considered as herbal 'wonder drug' due to the marvelous therapeutic effects and healing powers ascribed to it.
Botanical: Allium sativum (LINN.)
Family: N.O. Liliaceae
Synonym: Poor Man's Treacle.

Habitant: The Common Garlic, a member of the same group of plants as the Onion, is of such antiquity that it is difficult to tracethe country of its origin with certainty.

Description: Garlic leaves are long, narrow and flat like grass. The bulb is of a compound nature, consisting of numerous bulblets, known as 'cloves,' grouped together between the membraneous scales and enclosed within a whitish skin sac.

The flowers placed at the end of the stalk are whitish and grouped together in a globular head, or umbel, with an enclosing kind of leaf or spathae.

Part Used: Bulb. Constituents: Garlic bulb contains Alliin, enzymes (allinse, peroxidase, myrosinase), protein, minerals, vitamine B and C, lipids, aminoacids, and volatile oil (allicin, diallyl disulfide, linalool and allicin).

The active properties of Garlic depend on a pungent, volatile, essential oil, which may readily be obtained by distillation with water.

It is a sulphide of the radical Allyl, present in all the onion family. This oil is rich in sulphur, but contains no oxygen. The pecular penetrating odor of Garlic is due to this intense smelling sulphuret of allyl.

Medicinal Uses: In ancient times, Garlic was employed in treating leprosy, and was also believed to have beneficial results in smallpox cases. Its use as an antiseptic has long been recognized. Ointments and lotions containing garlic are often used to disperse hard swellings.

It is also employed as a poultice for scrofulous sores. Garlic syrup is an invaluable medicine for common colds, asthma, hoarseness, coughs, difficulty in breathing, and many other lung disorders, especially in chronic bronchitis, on account of its expectoration powers.

Rubbing its crushed-mix with lard on the chest and between the shoulder-blades has proven to relieve whooping-coughs. An infusion of the crushed bulbs, taken before and after every meal, is said to have a good effect on epilepsy.

A clove or two of Garlic, pounded with honey and taken two or three nights successively, is good in treating rheumatism and artheriosclerosi. The diuretic effects of garlic treat edema and prevents its future accumulation. When sniffed it revives patients suffering from hysteria.

Garlic juice made by boiling the crushed bulbs in milk is used as a vermifuge. Raw garlic is used to treat acne. There is evidence that it can help lower cholesterol levels. Allicin may prevent the production of artery clogging cholesterol.

Garlic can cut the risk of pre-eclampsia (raised blood pressure and protein retained in the urine) during pregnancy. It can also help improve the birth-weight of babies destined to be too small. Modern science has shown that garlic is a powerful broad-spectrum antibiotic.

As the body does not build up resistance to garlic, its positive health benefits continue over time. It is the only antibiotic that can actually kill bacteria and at the same time protect the body from the poisons causing infection.

Allicin, the garlic's main biologically active component, has an antimicrobial and cardioprotective effects and is used to alleviate cardiac pain.

Garlic also has antifungal effects. Allicin disables dysentery-causing amoebas and can even be a natural mosquito repellent.

Studies have shown that garlic has a powerful antioxidant effect. It helps digestion, keeps the coats of the stomach healthy. Garlic has always been known as an aphrodisiac and from a medical point of view it can significantly improve blood circulation.

Much information has been published regarding the role of garlic in cancer especially stomach and breast cancer. It is well known that garlic can strengthen the immune system which is vitally important for fighting cancer.

Recent findings support a growing body of evidence that garlic works as an anti-carcinogen in both cancer prevention and treatment.

Preparations: Raw garlic juice diluted with water, put on sterilized Sphagnum moss swabs, and then applied to the wound has antiseptic effects. It is used on infected wounds, acne, warts and varices. 2 grams of dried garlic powder used daily is shown to be effective in treating high levels of blood sugar and cholesterol.

Garlic syrup, made by boiling the bulbs till soft, adding an equal quantity of vinegar, and then sugaring and boiling down to syrup, was a popular remedy for asthma and non-inflammatory coughs for many years.

Caution: Raw garlic is very strong, so eating too much could cause irritation or digestive tract damage. Some people are allergic to garlic. Symptoms of garlic allergy include skin rash, fever and headaches. Garlic can also disrupt anti-coagulants, so it is best avoided before surgery.

A harmful interaction between garlic supplements and anti HIV/AIDS drugs has been reported in many studies. Garlic makes the retina more sensitive to strong light.

Pregnant women and those breast feeding should not use garlic, as it may result in cardiac discomfort in the fetus or infant. Garlic odor can be countered by consuming a tea spoon of honey, raw parsley or an apple.

Diet reduces heart attacks, strokes

A new study in the US offers strongest evidence a diet recommended for lowering blood pressure can save people from heart attack and stroke.

Researchers say they pursued more than 88,000 healthy women for almost 25 years, examining their food choices and seeing how many suffered from heart attacks and strokes.

Those who fared best had eating habits similar to those recommended by the government to stop high blood pressure.

The women followed the recommended plan, called the DASH diet, of fruits, vegetables, whole grains, low-fat milk and plant-based protein over meat.

Women with those eating habits were 24 percent less likely to have a heart attack and 18 percent less likely to have a stroke than women with more typical American diets, Associated Press reported.

Women in the study were in their mid-30s to late 50s when the research began in 1980. Previous research has shown this kind of diet can help prevent high blood pressure and cholesterol, which both can lead to heart attacks.

People might think, "I don't have high blood pressure, so I don't have to follow it," said Simmons College researcher Teresa Fung, the study's lead author. However, the results suggest, she said, that "even healthy people should get on it."

About 15,000 women in the study had diets that closely resembled the low blood pressure diet. They ate about twice as many fruits, vegetables and grains as the estimated 18,000 women whose diets more closely resembled typical American eating habits.

Sleep pattern predicts stroke risk

Scientists have suggested that habitual sleep patterns can predict the risk of suffering ischemic stroke in postmenopausal women.

According to a study published in the Stroke, getting nine hours or more of sleep every night is associated with a 60 percent increased ischemic stroke risk.

Findings also revealed that women suffering from sleep deprivation (less than six hours of sleep), are at a 14 percent higher risk of suffering stroke.

Albert Einstein College of Medicine researchers believe sleep apnea or restless sleep can be the underlying cause of the increased risk; however, the main reason is still unclear.

The study also showed that being retired or unemployed, smoking, being physically inactive or having cardiovascular disease, diabetes, hypertension, high cholesterol or depression are other factors associated with long hours of sleep.

Poor quality sleep linked to high mortality

People suffering from inability to sleep well -- irrespective of insomnia, sleep fragmentation or nightmares being the problem -- are at a higher risk of death.

According to several studies presented at SLEEP 2009, the 23rd Annual Meeting of the Associated Professional Sleep Societies, poor sleep increases the risk of several adverse health outcomes as well as death.

The findings of one of these studies found that sleeping for less than 5 hours per night increases the risk of death among elderly women but not elderly men.

Another study similarly showed that insomnia and sleep durations of at least 6 hours are as troublesome as obstructive sleep apnea (OSA), indicating that insomnia increases mortality rate five-fold.

Based on the Sleep Heart Health study, sleep fragmentation, transition from being awake to non-REM sleep and from non-REM sleep to being awake, is another risk factor tied to significantly higher mortality.

A US study reported that sleep habits have a significant impact on weight and BMI, indicating that twins who slept between 7 and 8.9 hours each night had a lower mean BMI (25.0 kg/m2) compared to those who regularly slept either more (25.2 kg/m2) or less (26.4 kg/m2) per night.

Other studies also reported that individuals with insomnia and objective short sleep duration are at an increased risk of high blood pressure, diabetes and mood disorders -- particularly depression.

Cornflakes linked to heart disease

Adopting a diet rich in carbohydrates interferes with the function of blood vessels, placing the individual at an increased risk of cardiovascular disease.

Previous studies had considered high blood sugar levels after meals as a risk factor for cardiovascular disease, not only in patients with diabetes but also in the general population.

High-glycemic meals, such as white bread, cornflakes and instant potatoes, are reported to increase blood sugar levels more than foods with low-glycemic index -- oatmeal, most fruits and vegetables, legumes and nuts.

According to a study published in the Journal of the American College of Cardiology, a diet rich in high-glycemic food is linked to higher risk of heart disease. High-glycemic foods not only increase postprandial blood sugar levels but also interfere with the function of blood vessels, a key variable in the development of hardening of the arteries and heart disease increasing the cardiac events.

"The main take-home message is that high-glycemic index carbs are dangerous since they reduce or inhibit endothelial function, which is the 'risk of the risk factors,' leading to atherosclerosis and potentially leading to heart disease," said Michael Shechter, the leader of the research team. Scientists therefore urged individuals to substitute high-glycemic carbohydrates with low-glycemic ones with the aim of lowering possible health concerns.

Laughter, heart medicine for diabetics

Hearty laughter is an effective medicine in diabetes sufferers as it can help reduce their risk of developing possible heart attacks.

Compared to their non-diabetic counterparts, diabetics are two- to fourfold more vulnerable to developing cardiovascular diseases. A new study however considers laughter as a cost-free medication for preventing heart disease in this group.

According to a study presented at the annual meeting of the American Physiological Society, laughter improves cholesterol levels in diabetics and subsequently lowers their heart attack risk. Laughing is associated with a 26 percent increase in the HDL (good cholesterol) levels; it also helps reduce C-reactive proteins -- a marker of the inflammatory diseases -- by 66 percent.

Some physicians believe laughter and humor can also help lower the increase in blood glucose that occurs after each meal. Scientists urge diabetics to adopt a healthy diet, exercise, watch their blood sugar, and add a little humor to their life.

Quietly, Worried Villagers Debate Dam Impact

VIENTIANE, April 2009 (IPS) - On the banks of a remote section of the Mekong River in southern Laos, an area known as Siphandone, villagers quietly debate the question, which is more important to Laos: fisheries or building dams?

The debate has been going on ever since a proposal by the Lao government to construct a hydropower dam on this section of the Mekong mainstream, which could have serious impacts on fish stocks that have fed local families for centuries.

It is part of a larger debate underway in the countries through which the Mekong River flows by, about the wisdom of building dams in the mainstream stretches of the river, which flows for 4,880 kilometres from its headwaters in Tibet, then through Myanmar, Laos, Thailand, Cambodia and Vietnam.

The location of the proposed dam is known as Khone Falls, Siphandone in Champasak province where the Mekong River forms a complex network of narrow channels, or ‘hoo' in Lao, at the point at which it flows into Cambodia.

The proposed dam will block Hoo Sahong, the deepest channel on that section of the river and where only few migratory fish can easily pass through at the peak of the dry season, April to May, when the water level of the Mekong is at its lowest.In truth, local people did not intend to offend the government or be misunderstood as being against the construction of the dam, said a fisherman from the Done Sadam village near the proposed dam site, who asked to be called Khampao.

But they fear the impacts it might have on the fisheries sector.The villagers living in the area where the dam will be constructed wonder how it will change their fortunes, particularly if the project blocks traditional fish migration routes.

According to the local authorities in southern Laos, nearly 2,500 people from four villages earn their living directly from fishing in the Hoo Sahong channel.”Our people are not aggressive and we have a tradition of not being against the government's development policies,” said Khamphao. ”We are not against the construction of the dam, but we want the government to study its impacts on our fish stocks. Otherwise the project will only make our lives poorer.”

Another fisherman from the area said fish were very important for the survival of his family and that without fish he would find it difficult to support his household.Khamphao said the money he used to build his house came from selling fish. ”Last year, I earned about 30,000 million kip by selling two tones of fish caught in the Hoo Sahong channel,” he said.Local people say the number of fish in local waters had been declining over the past decade due to the growing population and an increase in commercial fishing.

The Lao government signed an agreement in March 2006 granting the Malaysian engineering firm Mega First Corp. Berhad the exclusive mandate to carry out a feasibility study of the Don Sahong project.In February 2008, the company signed a project development agreement with Vientiane to push ahead with the scheme on a build-own-operate basis.

In a statement to the Malaysian stock exchange, the company said the dam, located in Champasak two kilometers from the Lao border with Cambodia, would be a ”run-of-river” facility with the capacity to generate between 240 and 360 megawatts of electricity to be used within Laos as well as being sold to neighbouring countries.

Villagers believe the problems relating to the dam have occurred as a result of a flawed decision-making process on the part of the government in which public consultation standards were not met.Public opinion has had no place in the decision-making process to this point and most decisions about the dam have been made by a small group of senior leaders in Champasak province and Vientiane.

Community consultation has been rushed, leaving the people of Siphandone feeling ignored by the dam construction company.Despite reports earlier this year that the Lao government had put the project on hold, the Don Sahong dam project appears to be going forward.

This is despite protests from technical officials who have said the project would severely impact the fishery sector, not only in Siphadone, but also upstream in the Lao provinces of Champasak and Savannakhet.

The project, potentially be the first dam on the mainstream of the Mekong River, has generated major concern internationally as well as in Laos' neighbour, Cambodia.Non-government organisations in Cambodia have requested the Lao government abandon the project due to fears of its adverse impact on fishery sector, including on the dwindling numbers of freshwater Irrawaddy dolphins, for which the Siphandone area is a major feeding ground.

The World Fish Centre, an international non-government organisation based in Phnom Penh that carries out fisheries related research, has reported the dam could effectively block dry-season fish movement between the lower Mekong plains and the upstream Mekong Basin.

The head of the environmental and social impact assessment division of the Lao Water Resource and Environment Authority, Bounkham Vorachit, said they had received the results of the feasibility study of the dam conducted by the company, but had yet to issue a final approval of the study.

She said the Don Sahong dam would not cause large-scale flooding, as it would be a run-of-river project.According to the Lao government, about 14 families, 80 people in total, will need to be relocated if the dam is built.Vorachit said she found many parts of the feasibility study to be quite clear, and that only the information related to the potential impact on fisheries was unclear. ”We have told the developers to study in more detail the migration of fish and what types of fish migrate to this area.”She said dam building had both negative and positive impacts.

But the important thing was to mitigate these impacts, so the construction of the dam will affect poor people's livelihoods as little as possible, she explained. ”These people rely on fish to feed their families,” Vorachit said.”If we believe the dam has more negative impacts than positive ones, our division will not approve it,” she assured.

In a recent interview with the Lao media, the deputy director of the energy department of the Lao Ministry of Mines and Energy, Khamchan Phalayok said progress on the Don Sahong project had been slow in recent months due to the global financial downturn.

Khamchan said that Thailand, as the main export market of the electricity produced in Lao dams, had yet to make any decision to buy electricity generated by the Don Sahong project. He added that banks were reluctant to offer loans for the project as well.

Laos has long desired to become the ‘battery' of South-east Asia by exporting electricity to the region, but its goal may be an unreachable dream as its neighbours are also rapidly developing their electricity production capacity.Since early 2006, the Lao government has granted permission to Thai, Malaysian and Chinese companies to conduct feasibility studies for several hydropower dams on the mainstream of the lower Mekong, including the Don Sahong project.

Drinking tea can reduce strokes

A new study in the United States has found out that drinking three or more cups of tea per day can reduce the risk of stroke. "By drinking three cups of tea a day, the risk of a stroke was reduced 21%," said Lenore Arab, professor of medicine at the David Geffen School of Medicine.

The professor also said that the more you drink, the better your odds of staving off a stroke. Drinking three more cups can drop another 21%.

The effect was found in tea made from the plant Camellia sinensis, not herbs, Arab said.

Researchers speculate that the anti-oxidant epigallocatechin gallate or the amino acid Theanine in tea may be what helps.

Some studies show anti-oxidants help prevent coronary artery disease, daily news reported Friday. "If we can find a way to prevent the stroke, or prevent the damage, that is simple and not toxic, that would be a great advance," Arab said.

Vegetarian diet cuts cancer risk

Compared to meat-eaters, individuals following a vegetarian diet are reported to be less likely to suffer from various cancers.

According to a study published in the American Journal of Clinical Nutrition, vegetarians and fish-eaters are less likely to develop cancer. The study shows eating less meat lowers the overall risk of suffering from cancer.

While previous studies had linked red meat to higher colorectal cancer risk, the new study reported this type of cancer to be more frequent among the vegans.

Scientists concluded that diet and different lifestyle factors play a critical role in determining an individual's risk of suffering from cancer.

They therefore urged individuals to eat five portions of fruit and vegetables a day, adding that adopting a vegetarian diet with the aim of lowering the risk of cancer needs more research.

Bitter English apple extends life span

Scientists say certain compounds found in the bitter English apple can help improve one's general health and extend the life span.

According to a recent study, the high epicatechin polyphenol content of bitter apple boosts heart health and circulation, leading to longer life.

This compound can tackle arterial stiffness (atherosclerosis) and high blood pressure, and therefore lowers the risk of suffering cardiovascular events.

The study showed that epicatechin helps maintain blood circulation by relaxing the arteries and increasing the blood flow.

Findings revealed that adding epicatechin to the regular diet is associated with a 17-year reduction in an individual's vascular age.

Based on the findings of the present study, scientists have developed a red-fleshed apple called Evesse which is believed to be rich in epicatechin.

Intelligent people live longer?

Having a lower IQ is reported to be strongly associated with a higher risk of death from accidents, coronary heart disease and suicide.

According to a Wellcome Trust study conducted in the MRC Social and Public Health Sciences Unit in Glasgow, cognitive ability determines an individual's risk of death.

Individuals who score higher on IQ tests are believed to exhibit healthier behaviors, smoke or drink less, adopt a healthier diet and exercise more; they therefore are less likely to die.

Preschool education programs and better nourishment were linked to higher IQ scores.

Education was considered as the sole factor influencing the relationship between IQ and death.

Scientists concluded that any attempts to improve educational opportunities may also have health benefits, leading to an increased lifespan.

Mental decline begins in late 20s: Study

Contrary to common belief that memory loss begins in old age, a new study finds that brainpower and mental ability decline in the late 20s.

According to the study published in Neurobiology of Aging, the peak mental agility and top mental performance occurs at the age of 22. In the late 20s, reasoning, spatial visualization and speed of thought begin to decline; memory however has been reported to remain intact until the age of 37.

The individual's performance on vocabulary or general information tests are reported to increase until the age of 60, indicating that only certain aspects of age-related cognitive decline begin in healthy adults in their 20s and 30s.

Scientists concluded that strategies adopted to keep mental decline at bay and inhibit Alzheimer's disease should be pursued much earlier.

Energy drinks could be troublesome

Energy drinks are reported to be associated with potential health risks in individuals with heart diseases and high blood pressure.

According to a study published in the Annals of Pharmacotherapy, drinking two cans of popular energy drink increases the blood pressure as well as the heart rate.

Healthy individuals can tolerate the extra pressure imposed to their heart; the condition, however, may be life-threatening in those suffering from underlying heart-related problems.

Caffeine and taurine have direct impact on cardiac function; the high levels of these two non-essential amino acids are believed to be responsible for the increases in blood pressure and heart rate following the consumption of energy drinks.

Scientists therefore urge individuals with hypertension or heart disease to avoid drinking energy drinks

Night owls more prone to heart disease

A new study finds that the risk of developing cardiovascular diseases significantly increases in men who go to bed after midnight.

Previous studies had linked chronic sleep loss to heart disease, diabetes, obesity and several health concerns. Some studies laid great emphasis on the role of a good night's sleep in maintaining an individual's heart health.

The fewer hours an individual sleeps each night, the higher the body mass index (BMI), blood pressure and triglyceride levels become.

A new study however has reported that going to bed late affects heart health regardless of sleep duration. According to the study presented at the 58th annual meeting of the American College of Cardiology, men who go to bed after midnight are more vulnerable to arterial stiffening -- an early stage of atherosclerosis and heart disease --, even if they sleep for at least seven hours.

Unhealthy late-night habits such as drinking more coffee to stay awake are believed to be responsible for the increased risk of cardiovascular problems in these individuals.

Feeling tired and exhausted increases the stress level - a significant risk factor for heart disease - and adversely effects cardiovascular health.

G20 summit members decide to dance to US tune and agree to waste 5 trillion dollars

A compromise, the American style, became the main result of the G20 summit in London. The world’s leading countries decided to boost the world economy with the help of grand investments, which goes along the US model of the anti-crisis struggle. Such an approach may result in the loss of control over the situation, economists say. The United States and Great Britain solve their own problems first and foremost.

The leading countries of the world achieved “almost a historic compromise” as a result of the G20 summit, as German Chancellor Angela Merkel put it. The twenty countries, which make up to 80 percent of the global GDP, gathered in the British capital to solve the future of the world financial system.

Many analysts said that they were not expecting any landmark decisions to be made because of the considerable differences between the participants of the summit. US President Barack Obama and British Prime Minister Gordon Brown insisted that only considerable investments in the international economy could save it from decline.

France and Germany did not support the idea. The two countries believe that the solution of the problem lies in the reforms and tough regulations of the whole international financial market. Yet, the USA and Britain were not willing to give more market-regulating powers to financial structures.

In addition, France stood up for sanctions against offshore zones, where taxation can be avoidable. French President Nicolas Sarkozy even threatened to leave the summit if it was not going to bring any certain results.

China and Russia suggested the creation of new reserve currencies to avoid the US dollar peg, although the countries were not persistent in their proposals.
As a result, the summit members agreed to spend $5 trillion on the solution of current economic problems before 2010. British Prime Minister Gordon Brown said that the funds should help the economy grow by four percent.

"Today's decisions, of course, will not immediately solve the crisis. But we have begun the process by which it will be solved," Brown said.

It was originally reported that the amount of financial assistance would make up only $1 trillion, though. The world has thus made a choice in favor of the US strategy.
“America is the world’s leading country, which makes it impossible not to listen to what they say,” Aleksei Belyanin, an expert with the International Institute for Economy and Finance told Bigness.ru.

No one knows which decisions would be absolutely correct under the conditions of the current crisis. The world does not have an experience, which it could use in overcoming the crisis conditions. The world has no other way out.

The G20 also decided to make the list of ‘tax haven’ countries to struggle against offshore zones in which billions of dollars are kept out of reach. The members also agreed not to make bonus payments to top managers who resorted to governmental assistance over their critical financial condition of their companis.

As for the idea to create new reserve currencies, there were no decisions made on the matter. The issue, which Russia proposed, was not even listed on the agenda of the summit. The G20 only promised to give it another consideration some time later.

Drinking hot tea increases cancer risk

Iranian scientists have found that drinking hot tea increases the risk of esophageal cancer, the British Medical Journal reported.

The study published on Friday said that drinking black tea at temperatures of 70C or higher increased the risk of the cancer, as it damaged the tissues of the throat.

A team led by the Tehran University of Medical Sciences conducted research to study the drinking habits among 300 people diagnosed with the disease in the northern province of Golestan.

The research showed that those drinking hot tea increased the risk as twice while drinking very hot drink could raise the risk to eightfold. The study backed previous findings that hot liquids may cause damage to the throat's epithelial lining and lead to cancer.

The study concluded there was no link between the amount of tea consumed and the risk of cancer but that the speed of drinking was an important factor. Esophageal cancers kill more than 500,000 people worldwide each year.

Tobacco and alcohol are the main factors linked to the development of esophageal cancers in Europe and the American nations.

Health benefits of fruit juice

Scientists believe drinking fresh fruit and vegetable juice is an easy way to obtain more vitamins and minerals in the daily diet.

Fresh juice is a rich source of bio-available vitamins and minerals; vitamins are important compounds for activating the enzymes, the catalysts in hundreds of body chemical reactions including digestion and energy production.

In addition, the body absorbs more vitamin and minerals by consuming fresh juice compared with whole fruits and vegetables.

Vitamins and minerals reduce the risk of strokes or heart attacks, improve the hair and nail condition, and provide essential compounds necessary for growth, health, normal metabolism and physical well-being.

The following is a list of juices and their effects on the general health.

- Carrot + Ginger + Apple - Boosts and cleanses the system.

- Apple + Cucumber + Celery - Prevents cancer, reduces cholesterol, and allays upset stomachs and alleviates headaches.

- Tomato + Carrot + Apple - Improves the skin complexion and bad breath.

- Bitter gourd + Apple + Milk - Prevents bad breath and reduces internal body heat.

- Orange + Ginger + Cucumber - Improves Skin texture and moisture and reduces body heat.

- Pineapple + Apple + Watermelon - Dispels excess salt, nourishes the bladder and kidney.
- Apple + Cucumber + Kiwi - Improves skin complexion.

- Pear and Banana - Regulates sugar content.

- Carrot + Apple + Pear + Mango - Clears body heat, counteracts toxicity, decreases blood pressure and fights oxidization.

- Honeydew + Grape + Watermelon + Milk - Due to its rich vitamin C and B2 content, increases cell activity and strengthens body immunity.

- Papaya + Pineapple + Milk - Due to its rich vitamin C, E and Iron content, improves skin complexion and metabolism.

- Banana + Pineapple + Milk - Prevents constipation.

Bananas cut risk of renal cancer

Recent studies suggest the regular consumption of bananas is effective in promoting kidney health and cutting the risk of renal cancer.

According to the results published in the International Journal of Cancer, due to the high amounts of potassium, individuals who eat bananas four to six times a week halve the risk of developing kidney cancer compared to those who do not eat the fruit.

About 190,000 cases of kidney cancer are diagnosed each year. Risk factors include smoking, high blood pressure, obesity, exposure to toxic chemicals such as asbestos and cadmium, and a high intake of fruit juices.

Bananas also lower blood pressure, regulate heart function, promote bone health, and protect eyesight.

Alternative medicine: Tomato

Tomatoes are not only heart healthy but can also fight several types of cancer and help develop healthy teeth, bones, skin and hair.

Botanical: Lycopersicon lycopersicum Family: N.O. Solanaceae Synonyms: Lycopersicon, pomme d'amour, pomodoro Habitat: The tomato which originated from the highlands of the west coast of South America is now available all over the world.

Description: Tomatoes are perennial vines, typically reaching 1-3m in height. The fruit botanically classified as a berry has fleshy internal segments filled with seeds and a watery matrix.

The tomato's predominant colors are red, yellow and green; however, purple and brown ones are also produced. They range in size from small cherry tomatoes to medium plum/roma tomatoes to large slicing/beefsteak tomatoes.

Part Used Medicinally: Fruit Constituents: Tomatoes are an excellent source of vitamin C and other vitamins like A, B1, B2, B6, E, K and niacin. They are rich in molybdenum, potassium, magnesium, iron, folate, copper, phosphorous, manganese, dietary fiber and chromium. In addition, tomatoes contain small amounts of nicotine (coumaric and chlorogenic acid).

Containing only 20 calories, they are a good source of phytochemical lycopene, beta-carotene and several other carotenoids. Medicinal Uses: Tomatoes are rich in antioxidants which play a key role in maintaining a healthy immune system and fighting against infection. Due to their high content of lycopene (a powerful anti-oxidant) and phytonutrients, tomatoes lower the risk of prostate, colorectal, pancreatic and stomach cancers.

The consumption of tomatoes with fat-rich avocado, nuts and olive oil increases the fruits anti-cancer properties. Eating tomatoes and broccoli together has shown better results against prostate cancer. Two powerful compounds found in tomatoes, coumaric acid and chlorogenic acid, are thought to block the effects of nitrosamines, thus reducing the risk of lung cancer.

The tomato's high antioxidant content prevents from inflammation and the progression or severity of atherosclerosis, diabetic complications and asthma.

The tomato's high potassium content makes it an effective stroke preventer and lowers blood pressure. The vitamin K found in tomatoes helps maintain healthy bones by activating osteocalcin, a protein which anchors calcium inside the bones.

It also helps prevent hemorrhages. Tomatoes are acidic, so they may upset the stomach in individuals with gastrointestinal discomfort. Individuals with high cholesterol levels, those whose work involves traveling long distances, those who have recently undergone a surgical procedure and smokers benefit from this fruit. The blood thinning effects of tomato juice are noteworthy for individuals at higher risk of blood clot formation.

A tomato-rich diet helps improve skin texture and color. Tomatoes help in liver congestion (cirrhosis) and gallstones. The nicotinic acid in tomato can help reduce blood cholesterol and prevent heart diseases.

A high dietary intake of tomato products helps lower LDL and cholesterol levels. Its high chromium content helps control blood sugar in diabetics and reduces the risk of developing cardiovascular disease in type 2 diabetics.

Tomatoes are heart-healthy because their vitamin B6 and folates are needed to help the body convert homocysteine, a potentially dangerous chemical, into other benign molecules. High levels of homocysteine can damage blood vessel walls and increase the risk of heart attack and stroke.

Tomatoes can also fight chronic degenerative ailments such as atherosclerosis, osteoporosis and Alzheimer's disease. Tomatoes are a good source of riboflavin, which helps reduce the frequency of migraine attacks.

Preparation: Using a whole tomato is more recommended as it contains more lycopene. Bright red tomatoes have the highest amounts of beta-carotene and lycopene. Cooking tomatoes in oil especially olive oil helps the body absorb more lycopene.

It is important not to cook tomatoes in aluminum cookware since their high acid content will interact with the metal causing deleterious health effects.

It should be noted that cooking and canning do not reduce the nutritional value of tomatoes. Concentrated tomato products such as tomato paste are recommended over whole fresh tomatoes as they deliver more carotenoids and protect the skin against the damaging effects of the sun. Caution:

The tomato plant's leaves contain toxic alkaloids. Tomatoes are one of the foods most commonly associated with allergic reactions including eczema, hives, skin rash, headache, runny nose, itchy eyes, wheezing, gastrointestinal disturbances, depression, hyperactivity and insomnia. I

Individuals who suspect food allergy to be an underlying factor in their health problems should not use this fruit.

Vitamin C lowers gout risk in men

Men who take high amounts of vitamin C supplements are placed at a lower risk of developing gout, a common inflammatory joint disease.

According to a study published in the Archives of Internal Medicine, the regular intake of supplements rich in vitamin C such as sprouts, peppers and oranges lowers the risk of gout in men. Those who take 1,000 - 1,499 mg vitamin C per day are reported to be at a 34 percent lower risk of developing gout.

Vitamin C alleviates the pain associated with gout by tackling the inflammatory processes and lowers uric acid levels - high levels of which form crystal deposits in and around joints, causing the pain and swelling associated with the condition.

Scientists urge individuals at risk of developing gout - overweight individuals and those taking certain medications as well as individuals who drink too much alcohol, and following an unhealthy diet high in meat -- to adopt a healthy diet that is rich in vitamin C.

Optimistic women live longer, healthier

Optimistic women who tend to see the glass half full rather than half empty live longer and much healthier, a new study has found.

According to the study presented at the annual meeting of the American Psychosomatic Society, women who expect good rather than bad things to happen are 14 percent less likely to die from any cause.

Compared to their pessimistic peers, optimists are more likely to be slim and physically active and are less likely to smoke. They are also less prone to high blood pressure and diabetes. Their strong social relationships helps them cope with chronic stress, lowering the risk of cardiovascular diseases.

The risk of death secondary to heart problems is reduced by 30 percent in these women. "Cynically hostile" women considered as highly mistrustful individuals are 16 percent more likely to die from any cause and 23 percent more vulnerable to death from cancer. Scientists concluded that optimism is directly linked to longevity.
