Portion Size 101: How to Determine How Big Your Food Portions Are


Portion Size 101 How to Determine How Big Your Food Portions AreIn a world where 21-ounce cans of soda containing 210 calories and 58 grams of sugar is considered medium size, figuring out what a “normal” portion looks like can be tricky.


Even healthy foods can be taken out of proportion. How many servings of salad did you really put on your plate? And what do health experts mean when they recommend eating two servings of fish a week? Understanding what constituents a “normal” portion size will help you cut back and take control.






How to Eyeball It

A good way to measure out normal portions is to size your food against commonly used objects. Here what one serving of the following looks like:


Breads, Cereals, and Grains:

  • 1 slice of bread-size of an index card
  • 1 small roll-size of a yo-yo
  • 1 bagel, a [5 oz.] can of tuna, 1/2 cup of rice or pasta-enough to fill a cupcake liner
  • Fruits and Vegetables:
  • 1 medium orange or apple-size of a tennis ball
  • ¼ cup dried fruit-size of a large egg
  • 1 cup of green salad-size of an adult fist
  • 1 small potato-size of a computer mouse


Proteins (Meats and Nuts):

  • 1 oz. of nuts – size of a ping pong ball
  • 3 oz. of meat (beef, chicken, fish, pork) -size of a deck of cards
  • 2 tbs. of peanut butter – size of two tea bags



  • 1 cup of milk 8 oz carton,1 scoop of fat free frozen yogurt[1/2 a baseball]
  • 1 oz. of cheese – size of a pair of dice
