What is the recommended serving size of whole grains?

Toby Smithson
Nutrition & Dietetics

A serving is considered 16 grams of whole grain (ingredient) in a whole grain product. Some exact serving sizes of whole grain foods are: 1/2 cup cooked brown rice, 100% whole grain pasta, oatmeal, or other cooked grain; 1 slice 100% whole grain bread; or 1 ounce of 100% whole grain cereal. Check the label for the whole grain symbol to help you decipher if a product is a whole grain.

Choose at least seven to eight servings a day, such as:
  • 1 slice bread;
  • 3/4 to 1 cup breakfast cereal;
  • 1/2 cup cooked cereal, grains, or pasta.
