The other group was instructed to eat snacks high in carbohydrates.

These packs included unsalted pretzels, graham crackers, animal crackers and Nutri-Grain/granola-key in bars.

Participants also wore accelerometers, which are devices that record activity levels.

Just note that a serving size of nuts is about 1 ounce.

Thats about14 walnut halves, 18 whole cashews or 49 pistachios.

But diet isnt the only thing that can influence disease risk.
