You don't have to feel bad about filling up on nuts. In fact, you can go nuts! Some studies show that eating a small handful of nuts can be as beneficial as cholesterol-lowering drugs when it comes to heart disease. And in 2003, the FDA approved a claim that eating nuts in moderation as part of a diet low in saturated fats and cholesterol may reduce the risk of heart disease. That makes the nutritional nut an important part of healthy diets. They're low in saturated fat and high in "good" monounsaturated and polyunsaturated fats. They're also high in fiber and Vitamin E, as well as antioxidants, which can protect against heart disease.
