A grain product is any food manufactured from wheat, rice, oats, cornmeal, barley, or any cereal grain. Whole grains and refined grains are the two subgroups of grains. Whole grains include the bran, germ, and endosperm of the grain kernel.
People who consume whole grains on a daily basis are less likely to become obese and have lower cholesterol levels. People who eat whole grains as part of a healthy eating style have a lower risk of heart disease, stroke, type II diabetes, and certain types of cancer due to the combination of nutrients (B-vitamins, trace minerals, antioxidants, phytochemicals, and fiber) contained in whole grains.
