Tree nuts linked to lower body weight, decreased type 2 diabetes risk: study

A large U.S. study has linked eating tree nuts with a lower body mass index and lower risk of type 2 diabetes. (Credit: Thinkstock)Go nuts — it's good for your health! A handful of nuts a day could keep you slim and lower your risk of type 2 diabetes, according to a study published in the Journal of the American College of Nutrition.

By "a few," researchers mean more than a quarter ounce of tree nuts — so a small handful of almonds, Brazil nuts, cashews, hazelnuts, macadamias, pecans, pine nuts, pistachios or walnuts. Sorry, your peanut butter and jelly sandwiches weren't included in this study.
