Health: Healthy Peanuts

It's yummy and sticks to the roof of your mouth. Now there's another reason to love peanut butter: eating nuts may lower your risk of developing type II diabetes.

In a new study in The Journal of the American Medical Association, Harvard researchers examined the medical histories and eating habits of 83,818 women and found that women who ate an ounce of nuts (any kind) five or more times a week were 27 percent less likely to develop the disease than those who rarely ate nuts. Researchers say there is no reason to believe the results don't apply to men. The "good" fats in nuts improve the body's use of insulin. That doesn't mean you can load up on high-calorie PB&J sandwiches. Instead, sub nuts for less healthful items in your diet. As long as kids aren't allergic, peanut butter is great for them. Adds Dr. Frank Hu, the author of the study: "For my kids I pack a peanut-butter sandwich almost every day."
