Lean meat, pork liver, fish and egg yolk have higher zinc content, among which oysters have the highest zinc content. According to laboratory tests, the zinc content in animal foods is generally high, and the zinc content in each100g of animal foods is about 3-5mg, and amino acids produced after animal protein decomposition can also promote the absorption of zinc. Zinc content in plant food is less.
Every100g of plant food contains about 65438 0 mg of zinc. There are beans, peanuts, millet, radish and Chinese cabbage with high zinc content in various plant foods.
In addition, in addition to some common zinc supplements in daily life, if zinc deficiency is serious or you want to supplement zinc faster, you can take some protein zinc preparations appropriately, and the effect of zinc supplementation will be better and more comprehensive.
Through the study of sea cucumber, it is found that sea cucumber is rich in trace elements, and zinc is one of them. At the same time, sea cucumber is also rich in arginine, which has a certain therapeutic effect on male sexual dysfunction.
Physiological function of zinc
Promote the growth and development of human body
The absence of children and adolescents during their growth and development will lead to stunting. When the lack is serious, it will lead to dwarfism and mental retardation. Zinc is the key to the growth of brain cells. Zinc deficiency will affect the function of the brain and reduce brain cells.
Maintain the normal appetite of human body.
Zinc deficiency can lead to decreased taste, anorexia, partial eclipse and even pica.
Enhance human immunity
Zinc is a nutrient for thymus development of immune organs. Only sufficient zinc can effectively ensure the development of thymus, differentiate T lymphocytes normally and promote cellular immune function.
Promote the healing of wounds and wounds
Zinc supplements were first used in clinical treatment of skin diseases.
Affect vitamin A metabolism and normal vision.
Zinc is good for eyes in clinic, because it can promote the absorption of vitamin A, and the absorption of vitamin A cannot be separated from zinc. Vitamin A is usually stored in the liver. When the human body needs it, it will be transported into the blood. This process relies on zinc to complete the "mobilization" work.
Maintain the normal spermatogenic function of men
Zinc is abundant in male testis and participates in the whole process of sperm formation, maturation and capacitation. Once men are short of zinc, it will lead to the decrease of sperm quantity and vitality, poor liquefaction of semen, and eventually lead to male infertility. Zinc deficiency can also cause adolescents to have no secondary sexual characteristics and abnormal reproductive development.
It regulates various enzymes and receptors that affect the physiological functions of the brain.
Zinc plays a very important role in the physiological regulation of various mammalian brains, is indispensable in the regulation of various enzymes and receptors, and also affects the structure and function of the nervous system, which is related to the occurrence and development of mental disorders such as obsessive-compulsive disorder.
In addition, zinc is closely related to the biosynthesis of DNA, RNA and protein. When the human body is short of zinc, it may lead to various adverse effects, leading to emotional instability, paranoia, depression, decreased emotional stability, cognitive impairment and so on.
