Are nuts part of your daily diet? If you answered no, you may want to add them to your grocery list. Research shows that eating nuts can boost your health and help you live longer.
For example, one 2019 study in the journal Antioxidants suggested that consuming nuts in moderation as part of a healthy diet may help lower your risk of many illnesses, such as cancer and heart disease. They may even add a few years to your life.
Nuts are loaded with important nutrients, including fatty acids, protein, vitamins, and minerals. But they also tend to be calorie-dense, so remember to stick to modest portions when you snack.
