Got "good" fats? Monounsaturated fats in particular can help reduce "bad" LDL cholesterol levels when you eat them in place of unhealthy saturated or trans fats. You'll find these heart-healthy fats in foods such as avocados, peanut butter and nuts like hazelnuts, almonds and pecans. Vegetable oils such as olive, canola and peanut are also rich in monounsaturates. Don't go overboard, though;all fats, even healthy ones, are high in calories. A handful of nuts or 2 tablespoons of olive oil, for instance, is all you need to help your heart.
