Nutritional Benefits of Grains

Grain foods are one of the major food groups

as part of an overall healthy eating plan. MyPlate, which is the tool developed by the U.S. Department of Agriculture (USDA) to help Americans make healthful choices, allots about one-quarter of a standard plate for grain foods, approximately the same amount as proteins, fruits, and vegetables.1  When you think about a meal for breakfast, lunch, or dinner, you should aim to have about one-quarter of that meal coming from grain food sources. That can be as simple as a plate of chicken with rice and vegetables, or a mixed-dish meal such as chicken-noodle soup with vegetables, or a Hawaiian pizza with ham, cheese, and pineapple with tomato sauce (the pizza crust provides grains).

And while MyPlate encourages Americans to make half their grains come from whole grain sources, there’s a role for enriched grains, too. Enriched grains – which are devoid of the grain’s bran and germ – tend to be fortified with essential nutrients. In fact, in 1998 the Food and Drug Administration (FDA) required that all enriched wheat products be fortified with folic acid as a way to prevent neural tube defects during early pregnancy.2  The mandatory folic acid fortification is one of the most successful fortification programs to date, and is responsible for a 35% reduction in neural tube defects since its inception.3 Food intake data shows that people are getting more folic acid from their grain food sources than they are from vegetables.4 Fortification of grains has also contributed to helping children meet their nutrient needs.5

Removing enriched grains from the diet entirely would also have unintended, negative consequences. A modeling study found that if only whole grains were required in the diet, with enriched grains or other substitutions not allowed, people would be at risk for nutritional deficiency. That’s because whole grains alone would be unable to fill the nutrient deficits left by fortified, enriched grains.6

Grains That Reign Supreme

Breads, cereal, pasta and rice are among the foods most associated with better diet quality and intake of essential nutrients, according to analyses done on food intake of both adults7 and children.8,9 Breads, including rolls, tortillas, as well as ready-to-eat cereals are meaningful contributors of folate, iron, thiamin, niacin and dietary fiber in children’s diet.9 Pasta, cooked cereals and rice were also associated with lower total fat and saturated fat intake of U.S. adults.7
