Question: 1 / 400

Which nutrient is particularly important for immune function?

Sodium

Zinc

Zinc is a vital nutrient for immune function due to its crucial roles in various biological processes. It is essential for the development and activation of immune cells, including T-cells and B-cells, which are integral to the adaptive immune response. Zinc plays a role in maintaining the integrity of the skin and mucosal membranes, which serve as the body's first line of defense against pathogens. Additionally, it acts as a cofactor for numerous enzymes involved in DNA synthesis, cell division, and protein synthesis, all of which are necessary for a robust immune response.

Adequate zinc levels have been linked to a reduction in the duration and severity of infections, illustrating its importance in enhancing the body's ability to fight off illness. This nutrient is often emphasized in discussions about immune health, particularly during cold and flu seasons, as well as in populations at risk for zinc deficiency, such as the elderly or those with certain dietary restrictions.
