There is a big difference between WHOLE grains and REFINED grains. Whole grains contain the entire grain kernel- the bran, germ, and endosperm. Refined grains have been processed, thus removing the bran and germ. Manufacturers do this to give grain foods a finer texture and improve their shelf life. The processing and refining of grains strips them of their fiber, iron and many vitamins and nutrients. Eating too many foods containing refined grains can lead to heart disease, diabetes and high levels of blood fats called triglycerides. That's why whole grains are great for kids, and refined grains should be avoided.
