The Portion Distortion Guide

A List of Serving Sizes

Selecting the right foods also means choosing portions that are proper serving sizes. The terms "portion" and "serving" are often used interchangeably, but they don't mean the same thing.

A "portion" is the amount of food you choose to eat for meals or snacks (like a plateful of pasta or a handful of raisins). In comparison a "serving" is the amount of food that experts recommend you eat (like 1 cup of milk or 1 ounce of bread). Servings are listed on a food's nutrition facts label too.

When choosing your portion, try to make it as close as possible to these recommended serving sizes.

Grains: Aim for 6-11 servings each day. Choose whole grains whenever possible.

Examples One serving equals That's about the size of
Bread 1 ounce (1 small slice, 1/2 bagel, 1/2 bun) Index card
Cooked Grains 1/2 cup cooked oats, rice, pasta Billiard ball
Dry cereal 1/2 cup flakes, puffed rice, shredded wheat Billiard ball

Fruits and Vegetables: Aim 5-9 total servings each day. Choose fresh fruits and veggies whenever possible.

Examples One serving equals That's about the size of
Raw fruit 1/2 cup raw, canned, frozen fruit Billiard ball
Dried fruit 1/4 cup raisins, prunes, apricots An egg
Juice 6 oz 100% fruit or vegetable juice Hockey puck
Raw vegetables 1 cup leafy greens, baby carrots Baseball
Cooked vegetables 1/2 cup cooked broccoli, potatoes Billiard ball

    How many grams of rice, potato and other whole grains is recommended to eat on a meal? So how many grams is one serving size? I don't know how many one cup is and I mean the dry version of rice and other foods - 11/22/2015 3:16:11 AM
  • Thank you for the info! - 11/21/2015 10:44:06 PM
  • In my case, it's more wishful thinking than portion distortion; however, I did not know that 1/2 C cooked oatmeal is the correct portion--that seems way to little. 8-) - 10/3/2015 9:16:31 PM
  • i think the reason that there is variation in the sizes and weights of cheese may be in part due to the moisture content the cheese. - 8/9/2015 11:04:30 PM
  • What a helpful article. I have seen lots of ways to measure food and ways to look at a portion. This article gave me images that I can actually imagine and will use. And guess what? I have been thinking portions are ALL bigger than these, for years! Gee, no wonder I am struggling. My tracking is very careful but my estimations have been far too optimistic. Time to get the WW scale out of the drawer and start being vigilant.

    At least I am consistently tracking and that is a huge victory. Now to DO IT RIGHT.

    (I would put a lol here but it is just not funny to make this kind of mistake for a long time, sigh...)

  • Cheese is my Achilles heel! Need help: Does anyone know what the dimensions are for a "slice" of cheese? And, can you weigh the ounce of cheese? because I've found one ounce of brie to be bigger than a pair of dice when weighed on a postage scale. I also have some mozzarella balls in a single serve says its an ounce and they are the size of a die but there are 3 of them. Ah cheese, why must you be delicious and confusing! :) - 8/8/2015 10:52:20 AM
    Thanks for sharing this, Nicole. Getting the right proportion gives one a right balance of food intake. This is great. I want to share this one. Ciao.

  • is there a printer-friendly version of this? maybe if i put it on the fridge, the chef will follow it! lol. - 6/12/2015 11:34:41 AM
  • It seems like eating 8-11 serving of grains, all that fruit, etc would have me eating a LOT more calories than I need to lose weight or even maintain. How do you eat all that and stay at 1300 cals? I track what I eat and weighing with a scale is really important. My brain always tries to fool me into what 1 oz looks like. - 1/30/2015 10:19:47 AM
    Yikes. This is helpful as I tend to go by what's on the box or can. The good news is that somehow, thanks to this site, after years of having NO success, I've lost five pounds just by counting calories and using the tracker. - 1/26/2015 9:50:31 AM
  • love the comment about a baseball sized glass of milk! - 1/23/2015 4:11:25 PM
  • Getting a food scale was a real eye opener for me. My "portions" were often almost double what was stated on the label. I also started using the "juice glasses" from my childhood. They hold only 4 ounces. - 1/23/2015 6:09:28 AM
    Portion control, portion control, everything in moderation, I have been using smaller plates too, - 1/23/2015 5:58:22 AM
  • I went and bought several sets of measuring cups, spoons and plastic measuring sets at the local Dollar Tree. It's so much easier to measure my food now with plenty of clean stuff. And I leave the correct cup in the cereal box and don't have to hunt one down. - 1/22/2015 2:20:52 PM
  • Would like to see better comparisons than spherical objects. They don't sit well on a plate or in a cup. Deck of cards and dice work, but trying to measure Pi is rather difficult. 6oz is the standard size of a small juice glass or those small yogurt, cottage cheese containers in the 6 pack. I've measured my serving spoons. My ladle is 1/3 cup so if it is flat it is a 1/3 if heaping 1/2. 8oz is 1 cup.
    Cereal is tricky. Watch the box for serving size. Many cans are multiple servings as well. I think the "about 2" servings should be banned. Anything less than 4 servings should document the whole container. - 1/22/2015 8:50:15 AM
