Calorie labels

Even though the food package says "reduced-calorie", do note the portion size: If you are eating 10 servings at one go, it's not exacty low-calorie in the end. Also look at other nutritional factors such as artificial flavoring and sodium content. Because low-caloric food often lack in taste, manufacturers usually add in more artificial sweeteners and MSG to enhance the flavor.
