ABSTRACT
Strong associations exist between consumption of whole-grain foods and other indicators of good health. Individuals who eat a lot of whole-grain foods are likely to be leaner; eat less fat, especially saturated and trans fats; be more physically active; and tend to smoke less. Worldwide, whole grains, also referred to as cereal grains, are consumed in greater amounts than any other food group. The role played by whole-grain foods in preventing the development of type 2 diabetes may relate in large part to their effects on body mass index. Consuming fiber-rich whole-grain food products often provides benefits of both types of fiber and contributes to heart health as well as to overall health. Studies indicate that people who eat whole grains have a lower risk of heart attack and high blood pressure compared to those consuming refined grains. Gluten is a protein found in certain grains and grain products, including wheat, barley, and rye.
