Green tea may help the elderly feel better mentally, reports the American Journal of Clinical Nutrition in a December 2009 article.
The Journal reported on a study from Tohoku University Graduate School of Biomedical Engineering in Sendai, Japan. The study found that elderly men and women consuming 4 or more cups of green tea had 44% less chance of having depression symptoms.
The study covered over 1,000 elderly Japanese citizens. Reseachers think that theanine, a substance found in green tea, may be the reason for the study’s results.
Researchers caution that more study is necessary.
