If you are trying to watch your portion sizes but just don’t feel like carrying measuring cups around, you can use a little trick to help remember the portion sizes of some foods. Associate the portion size with a familiar object. For instance, 1/2 cup of mashed potatoes or ice cream would be equal to the size of a racquetball — but not a softball! Using size associations is quick and easy and a fun way to get your kids to watch their portion sizes also! Here are more size associations: one serving of fruit = one tennis ball; three ounces of meat = one standard deck of cards; one teaspoon margarine = tip of your thumb; one ounce cheese = about four stacked dice; one cup mashed potato or broccoli = size of your fist; small handful of nuts or small crackers = one ounce.
