Any food made from rice, wheat, oats, cornmeal or other types of cereal grain is a grain product. Oatmeal, breakfast cereals, Bread, pasta, and tortillas are some of the many examples of grain products. Grains are typically divided into 2 groups, Refined Grains and Whole Grains. Whole grains basically contains an entire grain kernel ― the germ, bran, and endosperm. Whole grains includes oatmeal, whole cornmeal, brown rice, whole-wheat flour and bulgur. Refined grains are milled, it’s a process that removes the germ and bran. This process improve grain’s shelf life and give them a finer texture, but it also eliminates iron, dietary fiber, and numerous B vitamins. Most refined grains are enhanced. This means several B vitamins and iron are included after processing. The right amount of grains you eat depends on your sex, age, and type of physical activity.
