Which statement about zinc deficiency is true?

• A. It is commonly caused by excessive iron intake.
• B. It is associated with autosomal dominant disorders.
• C. It results in impaired immune function.
• D. It rarely affects children.

Answer: (C)

Zinc deficiency is known to impair immune function, making it more difficult for the body to mount effective immune responses. Zinc is a crucial trace element that plays a vital role in the function of various immune cells, including neutrophils, macrophages, and T lymphocytes. A deficiency can lead to an increased susceptibility to infections, delayed wound healing, and alterations in cytokine production. Additionally, zinc is involved in various enzymatic processes and is essential for maintaining the integrity of skin and mucosal membranes, which are important barriers against pathogens. Therefore, individuals with zinc deficiency often experience compromised immunity, which can result in a higher incidence of infections and poor overall immune response. This understanding reinforces the significance of zinc in nutritional assessments, particularly in populations at risk for deficiency, such as those with malabsorption syndromes, chronic illnesses, or poor dietary intake.
