On the basis of several clinical and preclinical studies, green tea, if consumed regularly, could have also antidepressant properties.
A recent double-blind study on healthy subjects showed why .
The regular consumption of green tea for five weeks has been proven to be helpful in preventing depressive symptoms.
How? Increasing the so-called "Reward learning", an important mechanism for survival and adaptation : its function is to let us learn through experience to make predictions and create expectations about consequences of events and behaviors.
Reward learning is a form of almost automatic learning of "approximate" predictive associations between certain events or behaviors and some of their possible rewarding consequences, that are therefore satisfying for the individual.
A deficiency in reward learning contributes to the development of anhedonia, an inability to experience pleasure and to perceive satisfaction, which is a key symptom of depression.
Therefore green tea , for its effect on reward learning, is very promising for the future development of natural remedies for prevention and treatment of depression.
And now, let’s have green tea!
