Estimating Serving Sizes

Serving sizes are different for various kinds of foods (meats, fruits and vegetables, etc.), liquid and solid foods, and cooked versus raw foods. It also can be difficult to judge appropriate portion sizes, which often are smaller than people think they are. In the absence of measuring devices, the hand can be used to estimate appropriate portion sizes of different foods. A closed fist is equivalent to a single serving of fruit or raw vegetables (chopped or whole). Two fingers or a domino are approximately the size of a single serving of cheese. A cupped hand holds about one cup of dried cereal or popcorn. An open palm represents a single serving size of meat, poultry or fish. The tip of the thumb is about the same size as a teaspoon of butter.
