Stay "Cheery" with Fruits and Vegetables

Happiness and mental health appear to rise with the number
of daily servings of fruits and vegetables a person eats, peaking
at seven portions. Researchers came to that conclusion after
studying the eating habits of 80,000 people.
Most Western governments presently recommend at least five
daily servings of fruits and vegetables for cardiovascular health
and as a protection against cancer, but the effects of diet on mental
well-being have been studied less often. "This study has shown
surprising results, and I have decided it is prudent to eat more
fruits and vegetables. I am keen to stay "cheery," said author Andrew
Oswald, PhD, of Britain's University of Warwick.
