Tea

A recent study conducted by Tohoku University, Sendai, Japan, reported in the September edition of the American Journal of Clinical Nutrition, has concluded that green tea consumption is linked to a decrease in psychological distress.

The researchers studied data gleaned from 42,093 Japanese citizens aged 40 and above.

The study was intended to discover whether there is in fact an inverse relationship between green tea consumption and psychological distress. It found that indeed the more cups of green tea a person drinks, the less stress is likely to affect them. Drinking five or more cups of green tea per day makes a person 80% less likely to suffer psychological distress than if they drank one cup or less.

The researchers concluded that: "the inverse relationship between green tea consumption and psychological distress persisted when respondents were stratified by social support subgroups or by activities in communities, even after adjustment for possible confounding factors."
