Serving Size Versus Portion Size

Confusion between 'servings' and 'portions' makes eating the right amount of food difficult.

by Carole Carson, Updated May 2011

Confusion between "servings" and "portions" makes eating the right amount of food difficult, particularly given the super-sizing trend. Potato chips bags, for example, contain 60 percent on average more than 20 years ago, while soft drinks are generally 50 percent larger.

Go From Fat to Fit

Serving sizes are standardized amounts of food with specific calorie and nutrient contents. Portions, on the other hand, are how much we choose to eat. To make sure you aren't overeating, you must know the size of a serving. The following everyday approximations should help.

Approximate Single-Serving Sizes

Grilled fish	Personal checkbook
Potato	Computer mouse
Meat serving	Deck of cards
Hard cheese	Four dice
Peanut butter	Tip of your thumb
Cup of fruit	Baseball
Apple/Orange	Tennis ball

Once we see how small servings are, most of us realize our portions are way too big. A typical serving of steak at a restaurant, for example, is the size of four decks of cards, the equivalent of four servings. Obviously, choosing to eat wisely means giving importance both to what and to how much we eat.
