Whole-grain foods are made from all edible parts of the grain, as opposed to products that use only the inside of the grain. Examples of whole-grain foods include whole-wheat bread, bulgur wheat, brown rice and quinoa. Other type of whole-grain foods are whole rye, millet, sorghum and whole oats.
Whole-grain products are healthy because they contain lots of vitamins, minerals, antioxidants and fiber. Eating more whole-grain foods may lessen the risk of heart disease, diabetes and obesity. The high-fiber content of whole-grain foods also creates a feeling of fullness, making it easier to eat less and thus maintain a healthy weight. Fiber helps to prevent constipation and to maintain a low blood sugar level.
