Detailed explanation-1: -Whole grains offer a “complete package” of health benefits, unlike refined grains, which are stripped of valuable nutrients in the refining process. All whole grain kernels contain three parts: the bran, germ, and endosperm. Each section houses health-promoting nutrients.
Detailed explanation-2: -Whole grains have the entire kernel (bran, endosperm and germ) intact therefore provide more fiber, selenium, potassium, magnesium and other nutrients. Refined grains on the other hand are milled and missing parts of their kernel thereby reducing their nutritional quality.
Detailed explanation-3: -According to MayoClinic, whole grains are healthier than other types of grains because they contain the whole sum of nutrients and proteins available naturally, while refined grains do not. The former have healthy fats, starchy carbohydrates, proteins, vitamins, minerals, fiber, and antioxidants.
Detailed explanation-4: -While fiber content differs among types of grains, in all cases the whole grain will have more fiber than its counterpart refined grain. For example, 100 grams of whole wheat flour contains 10 to 12 grams of fiber, while an equal amount of refined (white) flour contains 2 to 3 grams of fiber.
