Eating healthy and exercising doesn't give you an all access pass to eat anything you want. Everyone needs the same nutrients whether they exercise or not, as well as fruits and vegetables. When cooking your food, you should also limit solid fats such as butter, margarine, shortening, and lard. These foods may add flavor to your dishes, although they can also help raise your cholesterol as well. Therefore, you should try to add these foods and any foods that happen to contain them. To help keep your saturated fat, trans fat, and sodium low, you can check the nutrition facts label. Getting the right amount of fiber in your diet doesn't have to be hard.
