Serving Size and Servings per Container

We are used to saying “portion” or “helping” when we talk about how much we eat. “Serving size” is a more official or standard amount used for food labels. The nutrition facts given on a food label are based on the serving size. Remember: all of the nutrition information on the label is based upon one serving of the food.

Be sure to look at the number of servings in the package. Small packages may appear to be one serving. Often, they contain more. Snack food items are a good example. If you eat the whole package, then you must multiply the nutrition values by the number of servings in the package.
