Introduction to nutritional elements of black corn

The content of trace elements is high. The daily sodium intake of the human body should be 2-2.5%, and the daily potassium intake should be 1.9-5.6%. Humans are generally deficient in potassium, especially women. The content of several trace elements in black sweet corn is much higher than other cereal crops, especially the potassium content is as high as 6310-9050mg/kg, which is 3-8 times that of other cereals. It can regulate body fluid balance and resist fatigue, prevent and treat hypertension, cerebral thrombosis, maintain heart function, help regulate emotions, relax emotions, and stabilize psychology. Black sweet corn is a rare alkaline grain and has the function of weight loss.

Black sweet corn is high in iron and is a blood tonic. Iron is one of the most important elements in the human body. It is involved in the synthesis of hemoglobin, cytochrome and certain enzymes, and is also related to energy metabolism. Insufficient intake will cause disorders in physiological functions and metabolic processes, causing iron deficiency anemia. In addition, its zinc content is three times that of other grains, making it a very good zinc supplement. Zinc participates in the synthesis of nucleic acids and proteins and the metabolism of carbohydrates and vitamin A in the human body, and can maintain the normal physiological functions of the pancreas, gonads, pituitary gland, digestive system and skin. In particular, zinc deficiency in children affects puberty development and a series of changes such as anemia, diarrhea, and low immune function.

Black sweet corn is rich in calcium and phosphorus, which is 8-10 times that of other grains. The main physiological function of calcium and phosphorus is to form human bones and teeth. Calcium can maintain the normal excitability of nerves and muscles, and is the basis for promoting blood coagulation, muscle contraction and relaxation, and normal nerve conduction. If it is lacking in the human body, it can lead to rickets, osteomalacia, osteoporosis and other diseases. Black sweet corn has a high content of melanin. Most other black crops have a black skin and white inside, while black sweet corn has a transparent skin and a black and shiny inside. Melanin can stimulate the activity of human cells, reduce serum cholesterol, and has a positive effect on preventing and treating cardiovascular diseases such as arteriosclerosis and hypertension. It can improve human immunity, nourish the kidneys and nourish the skin, and has a good health care effect.

Black sweet corn has a high content of vitamin C. Most cereal crops do not contain vitamin C, but 100 grams of black sweet corn contains 4,831 mg of vitamin C. Vitamin C plays an important role in the metabolism of sugar and protein in the human body. It can promote the formation of intercellular matrix and collagen fibers. If vitamin C intake is insufficient, many tissues will atrophy, and in severe cases, scurvy will occur. In addition, vitamin C helps iron absorption, improves the function of the hematopoietic system, and is effective for iron deficiency anemia.
