Study: Eating fruit and veggies may lead to more happiness

The key to a happy life may come down to what you eat.

A new study finds eating more fruit and veggies each day and exercising regularly can lead to more happiness.

Researchers found that our ability to delay gratification and apply self-control plays a huge part in influencing our lifestyle decisions. In turn, this has a positive impact on our well-being.

Scientists found that men appear to exercise more, while women are more likely to eat more fruit and vegetables.

Since lifestyle-related illnesses are the main cause of poor health around the world, the findings could have significant implications for public health policy.

The study is published in the journal of "Happiness Studies."
