Most nuts are good sources of antioxidants, including vitamin E and phytochemicals. Peanuts are a good source of folic acid, a B-vitamin that may protect the heart by lowering homocysteine levels in the blood. High levels of this substance may damage arteries and lead to heart disease. Nuts supply varying amounts of minerals like copper, magnesium, calcium and potassium. Research is starting to show that diets rich in these minerals may help lower blood pressure or even prevent high blood pressure.
Nuts are also higher in fiber and a good source of plant proteins.
Most health experts would agree that nuts can be included as part of a healthy diet. Keep in mind that the serving size for nuts is small one ounce. A small amount of nuts goes a long way in adding taste and protecting your heart. Remember, though, adding nuts to your diet will not offset the effects of an unhealthy lifestyle. Being physically active, maintaining a healthy weight, eating a variety of fruits and vegetables, eating a diet low in saturated fat and cholesterol, and not smoking are among the most important steps you can take to reduce your risk of heart disease.
