Grains are a staple source of calories, carbohydrates, b-vitamins, and protein. Whole unrefined grains provide more protein for each carb because the bran and germ of grains contain the most protein per carb.
The current daily value (%DV) for protein is 50 grams per day, and is a target meant for most people. Grains high in protein include cornmeal, kamut (wheat berries), teff, quinoa, whole wheat pasta, wild rice, millet, couscous, oatmeal, and buckwheat. One cup of cooked whole grains provides between 6-20% of the DV for protein.
