The zinc or zinc is he chemical element of atomic number 30, whose symbol is Zn. It’s about a metal abundant in the earth’s crust, white and shiny, which can appear in the form of silicate, sulfur or carbonate.
The use of zinc dates back approximately one year 1,500 BC, according to objects found by archaeologists. However, it is believed that the reactivity chemistry of this metal and its capabilities were not noticed in ancient times.
Worldwide, the main zinc producers are China, Australia, Peru, USA and Canada, in that order. These five countries contribute almost 70% of the metal used throughout the world. planet.
Zinc is used to form alloys (such as brass), galvanize the steel and the iron to protect them from corrosion, and to make electric batteries, for example. It should be noted that zinc is an essential chemical element for humans, as it is used by various enzymes for the metabolism of proteins and nucleic acids.
The human body has about 40 milligrams of zinc per kilo that help the correct operation of the system immunological, wound healing and DNA synthesis, among other functions.
To maintain a good level of zinc, adults should ingest about 20 milligrams of zinc per day, through foods such as brewer’s yeast, beans, seaweed, pecans, soybeans, and whole grains. In case of zinc deficiency, the subject may experience delays in the increase, impotence, hair loss and abnormal smell.
Benefits and properties
At the beginning of the 1970s, the possibility of a deficiency of zinc in our body, since it is found in sufficient proportions in much of our diet. But it was soon discovered, through various studies with malnourished patients, that this phenomenon can occur as a direct consequence of inappropriate intake or poor absorption, whether the body eliminates more zinc than normal or requires it in greater amounts .
Some disorders related to the low level of zinc in the human body are anemia, hypogonadism, geophagia, diabetes, kidney failure and liver cirrhosis. With regard to its causes, a common example is chronic diarrhea, which contributes to the loss of zinc; on the other hand there is a hereditary childhood disease called acrodermatitis enteropathica, which prevents the normal absorption of zinc contained in food.
Likewise, people who sweat a lot and those who consume more Water of the advisable they lose zinc. This shows that the causes of deficiency can be both genetic and external.
These are some of the functions of this mineral element in our body:
* improves the developing of the reproductive organs and the functioning of the prostate gland;
* helps prevent acne, as it regulates the activity of the sebaceous glands;
* collaborates with the synthesis of proteins and collagen;
* helps fight stress;
* stimulates wound healing;
* improves the response of our immune system;
* protects the liver;
* plays an indispensable role in the formation of bones;
* it is a component of insulin;
* acts as a very powerful natural antioxidant;
* helps the body absorb vitamin A;
* It is a decisive factor in the development of the human being, from its gestation to its youth;
* collaborates with the health of the olfactory and gustatory systems;
* intervenes in the preservation of ocular functions.
Finally, it is important to note that in some cases it is necessary to reinforce zinc intake, as occurs during pregnancy or when experiencing diseases such as malnutrition or anorexia.
