The U.S. Food and Drug Administration (FDA) Nutrition Facts label appears on most packaged foods (see Figure 1). It tells you how many calories and servings are in a box or can. The serving size varies from product to product.
A portion is how much food you choose to eat at one time, whether in a restaurant, from a package, or at home. Sometimes the serving size and portion size match; sometimes they do not.
You can use the Nutrition Facts label:
- to track your calorie intake and number of servings; and
- to make healthy food choices by serving smaller portions and selecting items lower in fats, salt, and sugar and higher in fiber and vitamins.
