The nutritional value of corn
The vitamin content is very high
The vitamin content of maize is very high, 5~10 times that of rice and wheat, and the nutritional value of special maize is higher than that of ordinary corn.
2. Abundant plant cellulose content
The abundant plant cellulose contained in maize can stimulate gastrointestinal motility and accelerate excretion of feces, and can prevent constipation, enteritis and bowel cancer. It can bind and block the absorption of excessive glucose, and play the role of inhibiting the increase of blood glucose after meal. Fiber can also inhibit fat absorption, reduce blood lipid level, prevent and improve the occurrence of coronary heart disease, obesity, gallstone disease.
Rich in selenium and magnesium
The selenium and magnesium contained in corn have anti-cancer and anti-cancer effects. Selenium can accelerate the decomposition of peroxides in the body and inhibit malignant tumors without the supply of molecular oxygen. Magnesium, on the one hand, inhibits the development of cancer cells, on the other hand, promotes the excretion of wastes from the body, which is also of great significance to cancer prevention.
Maize also contains a longevity factor, glutathione, which, with the participation of selenium, produces glutamate oxidase, with the function of restoring youth and delaying senescence.
Maize contained in the yellow quality of corn can prevent the occurrence of senile macular disease. According to a 1994 study by harvard medical school and a number of research centers in the United States, higher intake of maize yellow can reduce the risk of age-related macular degeneration.
Rich in carotene and niacin
The carotene in maize, absorbed by the body, can be converted into vitamin A. Corn also contains niacin, which is much higher than rice. Niacin plays an important role in the metabolism of protein, fat and sugar, and can help us maintain normal functions of the nervous system, digestive system and skin. A lack of niacin in the body can lead to mental hallucinations, hearing voices, mental disorders, digestive keratitis, glossitis, diarrhea, and toadiness on the skin.
Rich in linoleic acid
Corn is rich in unsaturated fatty acids, especially linoleic acid content of more than 60%, linoleic acid can lower cholesterol and prevent its deposition on the lining of blood vessels, thereby reducing the occurrence of atherosclerosis, to prevent hypertension, cardio-cerebral vascular disease have a positive effect.
When choosing corn, the best choice 78 mature, too tender, too much water; Too old, with more starch and less protein. Choose maize, can be pinched with the hand, have pulp and color more white, can steam or cook to eat, taste and nutrition are best. Too much starch is too tender; If you don't pulp, the corn is old.
To preserve the corn, remove the husks and whiskers, clean and dry them, wrap them in plastic wrap and refrigerate them in the fridge.
Maize susceptible to moisture and mildew, produce flavotoxin good substances, preservation should be placed in a cool dry place.
