A study led by researchers from the National University of Singapore (NUS) and published in the journal Aging (June 14, 2019) has found that regular tea drinkers have better organized brain regions—which is associated with healthy cognitive function—when compared to non-tea drinkers. After examining neuroimaging data of 36 older adults, the researchers found that individuals who consumed either green, oolong or black tea at least four times a week for about 25 years had brain regions that were interconnected in a more efficient way.
Past studies have demonstrated that tea intake is beneficial to human health, with positive effects including mood improvement and reduced risk of cognitive decline. “Our current results relating to brain network indirectly support our previous findings by showing that the positive effects of regular tea drinking are the result of improved brain organization brought about by preventing disruption to interregional connections,” says Feng Lei, PhD, assistant professor of psychological medicine at NUS Yong Loo Lin School of Medicine.
