Tea halves risk of dementia
Research from the University of Singapore shows that drinking two to three cups of tea a day can halve the risk of early signs of dementia. In a study of lifestyle habits of 2,500 people aged 55 and over, it was found that sipping through a couple of cups of black tea per day can cut the risk of cognitive decline by 55%, and up to 63% for heavy tea drinkers. According to scientists, no protective effects on the brain were noted for caffeine, which indicates that polyphenols found in tea were responsible for increased brain function. It is believed that polyphenols prevent oxidation of brain cells and block build-up of plaques in the brain.
