Feeling blue? Green tea may help, study shows

TOKYO: Elderly people who drink several cups of green tea a day are less likely to suffer from depression, probably due to a "feel good" chemical found in this type of tea, Japanese researchers said.

Several studies have linked drinking green tea to lessening psychological problems and Kaijun Niu, of Tohoku University Graduate School, and colleagues found people aged 70 and older who drank four or more cups of green tea daily were 44 percent less likely to experience depression.

Green tea is widely consumed in many Asian countries, including China and Japan.
