You can lose weight, which means nothing. The whole grains in modern Chinese refer to rice, wheat, soybeans, corn and potatoes. At the same time, grains other than rice and flour are customarily called miscellaneous grains. Whole grains can regulate the stomach, which is good for diabetes. Replacing some flour and rice with coarse grains is helpful for diabetic patients to control their blood sugar. The rich nutrition contained in whole grains can prevent diseases and maintain health. Some whole grains contain pantothenic acid, which can release food energy and is an important component of fat metabolism; B vitamins help to burn calories.
