You already know you should eat fruits and vegetables for the nutrients they provide the body. But a new British study has again shown that the health benefits of produce don’t end there. Researchers at the University of Leeds have shown that eating fruits and vegetables can also improve your mood and mental well-being.

Researchers found that people whose diets included more fruits and vegetables reported being happier. Those who ate even just one extra portion of produce a day reported better life satisfaction than those who ate less. Researchers estimated that the extra portion could have the same effect on your mood as walking an additional 10 continuous minutes or more eight days a month.

Previous research conducted in Australia and New Zealand, and published in the British Journal of Health Psychology, showed a diet rich in fruits and vegetables makes people feel happier.

The latest study, entitled Lettuce Be Happy was published in Social Science and Medicine. It is based on a larger group of people who were followed for a longer period of time.
