Which mineral is essential for wound healing, immune health, reproductive maturity, and taste, and is found in foods like nuts and seeds?

• A. Selenium
• B. Zinc
• C. Copper
• D. Iodine

Answer: (B)

Zinc is the mineral that fits all four roles. It acts as a crucial helper for many enzymes, which enables wound healing and the synthesis of proteins needed for tissue repair. It supports the immune system by helping immune cells develop and function properly, contributing to a robust defense against infections. Zinc also plays a part in growth and sexual maturation, particularly through its involvement in hormone activity needed for normal development. Additionally, it is essential for taste perception, with zinc needed for the cells and signals that enable the sense of taste to function correctly. Nuts and seeds are good plant sources of zinc, though plant-based absorption can be challenged by compounds like phytates; soaking or fermenting can improve absorption, and pairing plant sources with other foods can help. This combination of roles is why zinc best matches all four traits.
