Whole grains are nutritionally superior to refined grains.
They are rich in protein, dietary fiber, anti-oxidants, minerals and vitamins. In most grains, the starchy endosperm contains protein, carbohydrates, iron, B-vitamins and fiber.
The germ, a tiny speck located at one end of each kernel, contains oil rich in health-promoting omega-3 fatty acids.
The bran is one of the best sources of fiber available in the plant kingdom.
