Wheat is not coarse grain, but one kind of fine grain. The other is rice. Fine grain is different from coarse grain in that its caryopsis is ground into flour to make bread, steamed bread, biscuit and so on. The taste is relatively soft and delicious, delicate and soft, and the quality of coarse grain can not reach this taste. However, because fine grain is refined, the nutrients are correspondingly lost, and the nutrients contained are less than coarse grain, but the normal nutrition supply can be guaranteed.
In addition to the white flour or rice milled from wheat, other crop products belong to coarse grain, including brown rice and rice of other colors that are not rolled completely. Because the processing of coarse grain is relatively simple, not as fine as the processing of fine grain, so the taste is a little rough, but because of this, it retains some nutrients that the fine grain does not have.
