What is Zinc? Zinc is an important mineral that is found in many foods. It is an essential mineral that becomes more important depending on certain factors. For example, people who do not eat enough zinc-containing foods or who sweat a lot may have higher zinc requirements or be at risk for lower levels since zinc can be lost through sweat. Insulin resistance can also suppress the body’s zinc levels.
Zinc is also important for healthy fetal growth and development during pregnancy, but also in infancy and childhood. Low levels can compromise immune system function. While high doses are not recommended, a higher intake for one or two weeks during the course of illness may be recommended by your healthcare provider and has not been shown to have serious side effects.
Zinc may be a useful nutrient for treating health problems like macular degeneration and HIV/AIDS.
Zinc must be consumed every day because the body has no way of storing this essential nutrient. The absorption of zinc can be decreased when too many phytates or antinutrients are consumed. These are typically found in grains, nuts, and seeds.
