The U.S. Dietary Guidelines of 2010 recommend that females between the ages of 14 and 50 consume 3 to 6 servings of whole grains each day, while males between the ages of 14 and 30 should consume 4 to 8 servings of whole grains each day. Males and females aged 13 and under need lower amounts of whole grains, depending on their age, as well as adults aged 51 and over. The amount of a single serving depends on the type of bread or grain.
