Green Tea
Researchers have found, for instance, that drinking
tea lowers levels of the stress hormone cortisol. And evidence of long-term health
benefits is emerging, too: drinking at least 100 millilitres (about half a cup) of
green tea a day seems to lower the risk of developing
depression and dementia.Studies results suggest that beneficial effects of green tea drinking might be due to alteration of serotonin and/or dopamine metabolism.
