You've probably heard that nuts are good for you.
But now a new major study has the science to back that up.
The study, one of the largest of its kind, followed more than 118,000 people for about 30 years.
It found that those who ate seven or more servings of nuts a week were 20-percent less likely to die from cancer, heart disease or any other cause than those who didn't over that 30-year period.
Researchers also say participants who ate nuts more often were leaner, less likely to smoke and more likely to exercise.
The study out of Harvard and two affiliated medical centers looked at both peanuts and tree nuts, such as pistachios.
