New findings on green and black tea leaves suggest that they lower the risk of dementia.
Regularly drinking a cup of green or black tea may cut the risk of dementia among older adults by 50 percent. The National University of Singapore conducted the research.
Findings published in the Journal of Nutrition, Health & Aging, also show that for those who are genetically at risk for developing Alzheimer’s disease, regular tea consumption may cut their risk by 86 percent.
Earlier research has linked drinking tea with better cognitive performance and a lower risk of cognitive decline by 86 percent. The research team studied the tea-drinking habits of 957 healthy Chinese adults age 55 and older from 2003 to 2005 and then tested their cognitive function every two years until 2010.
What they found is that regular tea drinkers (those who drank at least a cup, and up to three or more cups, a day) had the most benefits in terms of brain health..
Both green and black tea were protective, but they need to be brewed from tea leaves, either loose or in tea bags, lead author Feng Lei, assistant professor at the university’s Yong Loo Lin School of Medicine, said in an email. The results don’t apply to fruit or herbal teas.
Tea leaves contain flavonoids that have anti-inflammatory and antioxidant potentials that may protect the brain from vascular damage. Ready-to-drink teas made from powder, on the other hand, have only a small percentage of the amount of the flavonoids of brewed tea, according to the U.S. Agriculture Department.
Even though the study was conducted on older adults, the results could apply to all groups, as well, Feng said. He called it “a simple and inexpensive lifestyle measure” that might pay off big in later life. So, buy green or black tea leaves and steep up a pot of healthy tea. Drink tea every day and you will feel healthy and relaxed! Move over coffee, tea is taking the lead!
