[0002] The protein content of cereal grains is between 8-12%. Because the outer layer of the grain contains more protein than the inner layer, refined rice and flour, due to excessive removal of the outer husk, contain lower levels of lysine, phenylalanine, and methionine in cereal protein. It's important to mix a variety of grains or combine cereals with animal foods to increase the physiological value of cereal protein. Grinding grains makes them easier for the body to absorb.
