Young Girl with Oversized Burger - Kids and Portion Control


When kids follow the MyPlate recommendations for daily servings, they are well on their way to healthy eating and a healthy weight. Unfortunately, many kids today seem to be suffering from "portion distortion." When talking about what kids eat or drink, keep these definitions in mind.

  • Serving Size
    A serving is a specific amount of food or drink that is defined by common measurements, such as cups, ounces or tablespoons. Examples include recommended servings from MyPlate (the amount kids should eat) and the serving size on a Nutrition Facts label, which is the basis for all the other nutrition information on the label. In many cases, the serving size listed on the Nutrition Facts label is different from the MyPlate recommended serving size. In fact, many of the MyPlate serving sizes are smaller than those listed on the Nutrition Facts label.
  • Portion Size
    A portion is basically the amount of food that happens to end up on the plate. Think of portion size as the actual amount of food kids choose to eat at breakfast, lunch, dinner or as a snack. Portions can be bigger or smaller than the recommended serving size.

Visualizing Appropriate Portion Sizes

One reason kids may not be eating appropriately sized portions based on the recommended MyPlate serving sizes is that they may not recognize what a reasonable portion looks like. What does one-half cup of pasta look like? What about three ounces of chicken or two tablespoons of peanut butter?

The good news is that kids don't need a measuring cup or scale to measure the portions they should eat — instead, they can visualize them by using familiar objects, such as a tennis ball or CD, that are similar in size to recommended serving sizes. Before they eat or drink, they can think of the relevant object and choose a portion that matches its size.

Here are some tips to help you and your kids visualize portion sizes:
