Fruits and vegetables are one key to happiness, a new study has shown.
Researchers at Warwick University and Dartmouth found that those who consumed the most fruits and vegetables were happier than those who consumed very little.
The study looked at the diet of about 80,000 people in Britain, said WebMD.
Those who were found to consume eight or more servings of fruits and vegetables daily were significantly happier than those who did not, surveys showed.
Yet, after seven servings, further consumption did not increase happiness, reported the Washington Post.
“Our response was ‘Holy moly, it’s there in the data,’” study co-author Daniel Blanchflower of Dartmouth, told the paper.
The researcher said that even when other factors were controlled for the data still stood up.
“It might be that we just have all these vegetarians that are richer or happier."
“There are definitely issues of causality. At the same time, I think what we’ve done here is establish correlation," he added.
Despite the importance of fruits and vegetables, only about one in 10 Britons and Americans eat enough vegetables, reported WebMD.
The research will be published in Social Indicators Research.
