Nuts improve cardiovascular health
Researchers from Harvard Medical School and the Harvard School of Public Health have shown that nuts are healthy for the heart, especially for men at risk for heart disease, according to a report in the Harvard Men’s Health Watch.
Doctors theorize that nuts:
-
May help lower cholesterol, partly by replacing less healthy foods in the diet;
-
May contain mono- and polyunsaturated fats known to benefit the heart;
-
May protect against irregular heart rhythms because of the omega-3 fats;
-
Are rich in arginine, a substance that may improve blood vessel function; and
-
may help lower cardiovascular risk because of other nutrients in them.
Nuts are nutritional powerhouses, but high in calories. The article recommends substituting nuts for chips or cookies and avoiding nuts that are fried in oil or loaded with salt. As little as two ounces of nuts a week appears to help lower heart disease risk. Healthful choices include almonds, Brazil nuts, cashews, filberts, peanuts, pistachios and walnuts.
