In a blog on nutrition published by the Mayo Clinic we are told that portion control is an important factor in both weight loss and a healthy diet. Many people, however, have a poor sense of what constitutes a proper portion (or serving) of many foods. To correct the problem, the blog suggests that people use either food scales or measuring cups. However, when those are not available it helps to have visual clues to help judge proper portions. For instance, three ounces of fish is about the size of a deck of cards; one-half cup of pasta is the size of a hockey puck; one serving of fruit is the approximate size of a tennis ball.
The article pointed out that our appreciation of correct portion sizes has been vastly distorted by the the amount of food served in restaurant meals. The article also suggests that you test yourself by placing what you perceive to be proper portions on a plate or in a bowl. Then transfer your portions to a food scale or measuring cup to see how you did. With a little practice, you can soon learn to serve proper portions for optimum health and weight.
