Oct. 11, 2012 -- Grumpy and out of sorts? Grab an apple. Or a carrot. Or a banana.
Eating plenty of fruits and vegetables seems to boost life satisfaction, mental well-being, and happiness, according to a new study.
Researchers analyzed the diet habits of 80,000 men and women in Britain.
The more fruits and vegetables they ate, the happier they were. Those who ate seven servings daily were happiest.
"I think it's splendid to know that fruits and vegetables are likely to be good for your mental health as well as your physical health," says researcher Sarah Stewart-Brown, MD, professor of public health at Warwick Medical School in the U.K. "It's not surprising, as the two are related to each other."
The research is to be published in Social Indicators Research.
