Black tea to tackle Alzheimer's

Singaporean scientists have claimed that drinking two cups of tea a day halves the risk of developing cognitive decline and memory loss.

According to a study published in the American Journal of Clinical Nutrition, drinking two to three cups of tea every day cuts the dementia risk by 55%. The risk is reduced by 63% in heavy tea drinkers.

Findings showed that coffee does not have similar effects on reducing the risk of dementia, suggesting that antioxidant compounds in black tea are responsible for its anti-dementia effects.

The study revealed that tea's polyphenol content is effective in fighting the cerebral plaques that characterize Alzheimer's disease (AD).

Previous studies had reported that the high flavonoid content of tea helps fight several cancers and cardiovascular diseases, relieves headaches, and provides a calm mental state.
