Yaroslavl residents were told why they need to eat one orange a day


As scientists from Harvard have established, just one orange a day is enough to reduce the risk of depression by 20 percent.
This happens because this fruit, although by all biological standards it is a berry, increases the level of bacteria that stimulates the production of serotonin and dopamine - hormones of happiness.
By the way, the research lasted for decades, and one hundred thousand people took part in it.
