Is zinc harmful to humans? The harm of zinc to the human body

Zinc participates in the metabolic process of nucleic acid proteins, can promote the normal development of **, bones and sexual organs, and maintain digestive and metabolic activities. The specific effects include promoting the growth and development of the human body, maintaining the normal appetite of the human body, enhancing the human immunity, promoting the healing of wounds and wounds, affecting the metabolism of vitamin A and normal vision, and maintaining the normal spermatogenic function of men.

Zinc deficiency in developing children can cause anorexia, dwarfism, etc., so people call zinc "the element of life".

The adult body contains about zinc, and the concentration of zinc in the blood plasma is 10 20umol l. Excessive zinc intake can cause poisoning, such as excessive zinc intake can cause acute zinc poisoning, gastrointestinal symptoms such as vomiting and diarrhea; Inhalation of zinc mist in factories may have low-grade fever and cold-like symptoms; Chronic zinc poisoning may have symptoms such as anemia; Animal experiments can cause liver and kidney function and immunity to be impaired. The paint of some children's toys contains zinc, and children like to put the toys in their mouths, and often eat too much zinc can cause poisoning.

Zinc has very low toxicity. The various pathological reactions caused by excessive intake of zinc are mainly due to the mutual antagonism of zinc with elements such as calcium, selenium, copper and iron.

In general, if you eat a well-balanced diet, your body will not be deficient in zinc.

Everything should have a degree, and more or less is not good.

Zinc is a necessary trace element for the human body, if you don't supplement, it is easy to cause children's hair to be yellow, mental retardation, a large amount of supplementation is harmless to the human body, but it is more wasteful, more is waste.

trace elements, some people are also deficient in zinc.

After an excess of zinc in the human body, gastrointestinal symptoms such as nausea, vomiting, abdominal pain, and diarrhea can occur. It can also cause fever, anemia, stunted growth, joint bleeding, bone breakdown, and other diseases. Excess zinc is difficult to be excreted from the body, and the high zinc content in the body will also inhibit the body's absorption of iron, copper, calcium and other elements, vitamin C, and cause iron deficiency anemia; The result of affecting calcium absorption is a decrease in immunity and poor disease resistance.

Zinc supplementation must be examined by the hospital and diagnosed as a baby with obvious zinc deficiency before giving preparations such as zinc sulfate syrup or zinc gluconate under the guidance of a doctor.

Whether zinc alloys are toxic or not is related to the type and quality of the alloy.

Zinc alloy is an alloy composed of zinc based on other elements, common alloying elements are aluminum, copper, magnesium, cadmium, lead, titanium, etc. There are many types of zinc alloys and their effects on the human body vary.

Zinc alloy jewelry: good quality zinc alloy jewelry has little impact on people who are not sensitive; **Sensitive people may have allergic symptoms such as rash and itching after wearing it;

The damage caused to the body by excessive zinc in the human body includes:

1. Inhibit the activity and bactericidal power of phagocytic cells, thereby reducing the immune function of the human body and weakening the ability to resist disease;

2. Disorder cholesterol metabolism in the body and produce hypercholesterolemia;

3. Excessive zinc will inhibit the utilization of iron, and the mechanism of iron participation in hematopoiesis will be disordered, so that the human body will develop intractable iron deficiency anemia;

4. Long-term high-dose zinc intake can induce copper deficiency in the human body, thereby causing a series of physiological dysfunctions such as cardiomyocyte oxidative metabolism disorders, simple osteoporosis, and brain tissue atrophy.
