Studies have shown that whole grains can nourish the five internal organs. As early as ancient times, there was a saying that "one grain supplements one dirty". Cereals include millet, rice, wheat, soybeans and sorghum. Among them, millet can tonify spleen, soybean can tonify kidney and so on. Chinese medicine believes that whole grains can not only fill the stomach, but also be good food for the five internal organs.

Soybean tonifies kidney: Black beans in soybean are called "kidney valley". Traditional Chinese medicine believes that it has the effects of tonifying kidney and strengthening body, detoxifying and moistening skin, and has a good dietotherapy effect on kidney deficiency and edema.

Millet nourishes the spleen: Xiaomi is the first of the five grains, and it can replenish the spleen and stomach if eaten often. Millet is the top tonic for people with spleen deficiency and infirmity, which can tonify the middle energizer and prolong life.

Wheat nourishes the heart: Wheat is called "the price of five grains". Chinese medicine believes that it can nourish the heart and soothe the nerves, except for irritability. It has dietotherapy effect on eliminating female climacteric syndrome, spontaneous sweating, night sweats and dysphoria.

Sorghum nourishes liver: Sorghum and soybean belong to miscellaneous grains, but they are indispensable supporting roles in the whole grain. Sorghum has the effects of nourishing the liver and benefiting the stomach, astringing and stopping diarrhea, especially for people with chronic diarrhea. Eating it for a period of time will have a good effect.

Different colors of corn have different effects: the health care effects of different colors of corn are slightly different, mainly because they contain different varieties of pigments. Compared with white corn, purple corn contains more anthocyanins, so it has antioxidant and anti-aging effects. Yellow corn contains carotene and zeaxanthin, which is good for maintaining vision health.

The content of protein, fat and vitamins in sweet corn is 1-2 times higher than that in common corn, while the content of selenium is 8- 10 times higher. Among 17 amino acids, 13 is higher than that of common corn. However, sweet corn has a high sugar content, mostly sucrose and glucose, which easily leads to an increase in blood sugar. Waxy corn is rich in protein, vitamin A and vitamin B 1, and amylopectin, which is not suitable for diabetics. But old corn has high crude fiber content and low soluble sugar content, which is a very good choice for people who lose weight and have diabetes.
