1. Anti-aging: There is a kind of superoxide dismutase in human body, which is the most important protective enzyme in determining human life. Superoxide dismutase can only play its role under the catalysis of manganese ions. The important reason of human aging is that the antioxidant effect decreases with age. Superoxide dismutase can inhibit and eliminate the survival of free radicals and reduce the harm of free radicals to human body. Prevent lipid from over-oxidation, and play the role of anti-oxidation and anti-aging. If manganese is lacking, the antioxidant capacity of human body will be reduced, which will accelerate aging, leading to poor eyesight, tooth loss and white hair of the elderly. In addition, only manganese can play a normal role in the catalytic process of thyroxine. In order to promote the proliferation of cells and the decomposition and synthesis of protein, nucleic acid polymerase also needs the participation of manganese. Manganese deficiency will slow down cell metabolism and accelerate human aging.
2. Prevention of osteoporosis and fracture: Manganese also plays a certain role in reducing bone loss and preventing osteoporosis and fracture. This is because manganese participates in activating the enzyme system of chondroitin sulfate synthesis and promoting bone synthesis. Manganese deficiency in human body will inhibit bone synthesis. Over time, it will lead to cartilage dysplasia, joint deformity, enlarged bone pores, decreased bone hardness, decreased toughness, osteoporosis and easy fracture.
3. Manganese plays a certain role in human metabolism. Manganese participates in the metabolism of protein and is closely related to the synthesis of protein. Can improve the absorption and utilization rate of protein by human body. Manganese can also promote the synthesis of cholesterol in human body. Manganese can activate polysaccharide polymerase and galactosyltransferase in vivo, which is beneficial to the health of the elderly.
4. Manganese can prevent anemia. Manganese has certain influence on the function of human hematopoietic system. Some people's anemia is not iron deficiency but manganese deficiency, so iron supplementation doesn't work, and only manganese supplementation can cure it. In addition, manganese is also very important for the work of human brain and central nervous system. Once manganese deficiency occurs, especially in the elderly, symptoms such as slow response and memory loss often occur.
Manganese exists in all kinds of foods that people eat, but the content of manganese is different. Therefore, as long as adults, teenagers and children are not picky eaters and partial eclipse, and maintain the diversity of food varieties and the balance of nutrition, manganese will generally not be lacking. Foods containing more manganese are green leafy vegetables, tea, nuts and wheat, but seafood, fish, meat, root vegetables and carrots contain little manganese. Animal foods, such as milk, goat's milk and dairy products, have low manganese content, but high absorption and utilization rate in human body, which is one of the sources of manganese in human body. Some plant foods contain a lot of manganese, but the absorption and utilization rate in human body is very poor.
