Eating seven servings of fruits and vegetables each day is the key to happiness, according to a new study.

The study looked at a sample of 80,000 men and women in England, Scotland, and Wales and found the more veggies and fruit they ate, the happier they were.

This is the first study of such a large group that found eating better went beyond just your physical health. The subjects in the study reported on their exercise level, whether or not they smoked, and other common metrics.

The question now becomes whether there was a link that if people who are happy stopped eating fruit and veggies, would they become unhappy? And what's the connection to exercise?

We don't know yet if it's a coincidence that people who tend to be happier also eat healthier, or if eating healthier tends to lead to happiness.
