WANT A healthy heart? Then eat a lot of walnuts. Just 28 grams of walnuts a day would be perfect, recommends a recent study that found the nuts to be an excellent source of heart-friendly fatty acids. And, to boot, walnuts do not contain any cholesterol (The Lancet, Vol 341, No 8846).

Researchers at California's Loma Linda University put 18 male volunteers on two cholesterol-lowering diets -- one rich in walnuts and the other without walnuts -- without increasing the proportion of calories from total dietary fat. They found the cholestrol levels in the men put on a walnut-rich diet was significantly lower than in those on the other diet.
