Have Some Nuts
A handful a day (about 1 1/2 ounces) of nuts such as pecans, almonds and pistachios may reduce your risk of heart disease by lowering blood cholesterol. And walnuts, which are high in polyunsaturated fatty acids, also keep blood vessels healthy. Since all nuts are high in calories, stick with a palmful—and resist the temptation to eat them salted or coated with sugar.
