You are here: Micronutrients The benefits and harms of Zinc
Zinc is an important element of the human body and takes it on the content of the second place after the iron. Even in ancient Egypt used a zinc-based ointment, which contributed to the rapid healing of wounds. But as with any element of the periodic table, zinc calls for a precisely balanced approach. By just one milligram can determine the vector of action of metal. The benefits and harm of zinc have a fine line between that know better in theory than in practice.
Most researchers believe that today most people suffer from zinc deficiency in the body. However, some scientists are inclined to believe that the oversupply of zinc in the body leads to an imbalance of the immune system, as well as the deficit. Use of zinc is shown at a daily dose of 5 to 20 mg in combination with other micronutrients and vitamins. Particularly useful zinc, vitamin A, activating its operation and carrying out the movement of the vitamin in the blood to all the body's cells.
Zinc is found in the membranes of cells and protects them from damage, increases resistance to microbes. It can be used both externally in the form of antiseptic ointments, powders, and included in a diet enriched products.
Benefits for the body of zinc can occur both externally (zinc treats dermatitis, acne and slows the aging process), and internally - metal helps with inflammation of the gastrointestinal tract and kidneys. It is noticed that zinc affects the intellectual abilities (the level of the body member talented students is much higher than that of the lagging). It is also obvious benefits of zinc for men's health - member participates actively in spermatogenesis, but also prevents the development of prostate tumors.
Damage begins with a large metal overdose in the body - 150 mg-600 has a poison to humans, and 6 g of guaranteed death. When metal toxicity observed weakness, nausea and other symptoms of poisoning. Of course, at these doses, we rarely meet with the metal, but zinc harm can occur unbeknownst to us through indirect contact with the element. For example, drinking water from stoyaluyu galvanized vessels are not recommended - soluble zinc compounds will act negatively on the gastro-intestinal tract. The metal dust may cause pulmonary abnormalities. Zinc phosphide used to combat rodents is extremely dangerous to humans. Harm zinc is mainly manifested in contact with the element modifications in complex compounds. Although zinc metal itself is neutral for man.
To summarize - zinc is good for a person to the extent and only in the "edible form." Zinc rich germinated grain cereal, strawberries, lean beef, especially beef liver, green leafy vegetables, many varieties of nuts. But zinc utensils for cooking is not necessary.
