Eating nuts like almonds, pecans, walnuts, peanuts will help to lower blood cholesterol levels. Almonds are a rich source of the antioxidant vitamin E. Antioxidants are important in maintaining health and supporting the immune system. A diet that includes a regular helping of nuts but otherwise contains too much fat, salt, sugar and red meat, and not much fruit and vegetables, will still be unhealthy. So it is your overall diet which will determine your health.
