According to a study done by the Tohoku University Graduate School of Biomedical Engineering in Japan, nearly 40% of our seniors (over the age 70) show some signs of depression.
However, this statistic changes pretty drastically when just one variable is added: tea.
The study seems to elucidate that the regular consumption of tea (green tea especially, it seems), at least four cups a day, directly results in a 44% lower likelihood for seniors to struggle with depression than those who drank less than four cups.
The scientists believe that the reason for this tranquilizing effect is due to an amino acid found in tea, which we’ve discussed many times before, known as L-Theanine. L-Theanine is one of very few compounds that is able to cross the blood-brain barrier, which they believe is the key to tea’s salutary anti-depression benefits.
So be sure to give our seniors your time, respect – and tea!
