Whole wheat food, which is made of flour made from wheat that has not been removed, is darker and more crude than the fine flour that we usually eat, but is more nutritionally valuable because of the large amounts of vitamins, minerals and cellulose that are kept in the skin. Previously, whole wheat grains were referred to as "coarse grains" and considered food for the poor. Precision of the five cereals is an inner layer that provides carbohydrates and a small amount of protein, but fibres and other nutrients are not as good as whole wheat grains. The toast, the whole wheat, the milk powder, the bean sand, has greatly improved the rough taste, and the milk smells are rich。
