By Tiffany Tse Published on December 10, 2011 Share Tweet Pin Email Your fridge is stocked with wholesome ingredients. You've printed out an arsenal of good-for-you recipes. But now you're faced with a new problem: How do you determine the perfect portion-controlled sizes for your healthy snacks and meals? Use this simple guide that compares typical foods, including fish, pasta, and cheese, to everyday objects. It makes healthy eating easy! Meat One serving of cooked meat (about 3 ounces) is equivalent to a bar of soap. When you're doling out your portion, envision the foamy bar of Ivory in your shower! Hamburger Patty If you're in the mood for the grill, use a hockey puck to estimate the size of a ground hamburger patty. Pasta A serving of cooked pasta (about 1/2 cup) should match the size of your fist. Bread One serving of grains equals a piece of bread, a waffle, or a pancake. While a standard CD case is an appropriate size for the bread, the CD itself is a good guideline for the waffles and pancakes. Fish The only time your bank balance won't suffer when you take out your checkbook: when you're measuring it against a 3-ounce serving of fish! Oil One teaspoon approximates a single serving of fats and oils. No measuring spoons around? Use the tip of your thumb as a guide. Cheese One serving of dairy is about four small pieces of cheese. When you're slicing up cubes, keep in mind the size and shape of four die. Fruit Whether you're munching on an apple, plum, or peach, in general, a tennis ball equates to one serving size of whole fruit. Veggies Hit a home run with your daily veggie intake. A single serving of veggies (1 cup), such as broccoli or carrots, should be proportional to a baseball. Peanut Butter Indulge in a ping pong ball-sized serving of peanut butter (about two tablespoons) to keep your calories in check! Was this page helpful? Thanks for your feedback! Tell us why!
