It can happen to everyone to feel old and sad sometimes. Now a research performed in the United States reveals that it’s enough to drink Green Tea to get better.

Green Tea is not good only for the body, but also for the spirit, especially in old age, when it can happen to suffer from depression. According to a Japanese study, older men and women who drink several cups of this drink a day feel sad less likely.

Dr. Kaijun Niu, from Tohoku University Graduate School of Biomedical Engineering in Sendai, and his colleagues found that men and women aged 70 and more who drank four or more cups of Green Tea a day were 44% less likely to suffer from symptoms of depression compared to their peers who consumed less Green Tea.

Several studies in the past have already linked Green Tea consumption to reduced psychological problems. This led Dr.Niu to look for a connection between consumption of Green Tea and symptoms of depression in a group of 1,058 elderly people in relatively good health conditions. The results of this study were published in American Journal of Clinical Nutrition.

About 34% of men and 39% of women had symptoms of depression. These symptoms were serious by about 20% of men and about 24% of women. Overall, 488 participants in the study said they have drank four or more cups of Green Tea a day, 284 participants have drank three cups a day and the remaining 286 one or less.

Considering also other factors – such as gender, general nutrition, physical activity, medical problems, smoking, socioeconomic status and the use of antidepressant medications – the researchers noted, anyway, a protective effect of Green Tea against depression.

There was no evidence, however, of an association between decreased symptoms of depression and consumption of other types of tea or coffee. According to the researchers, the positive effect of Green Tea is due to the presence of the amino acid L-theanine, which seems to perform the action of a tranquilizer on the brain. It has a calming effect because it affects mental and physical relaxation, reduces stress levels and reduces the feeling of anxiety. In addition, it stimulates the hormone of happiness dopamine and thus ensures good mood.

Although the depression is a disease that should be treated with an appropriate mix of medication and psychotherapy, Green Tea could anyway contribute to the well-being of those who feel a little bit ‘down.
