What is the primary function of zinc in the body?

Zinc plays a crucial role in supporting immune function and wound healing, making it essential for maintaining overall health. It is a vital trace mineral that acts as a cofactor for numerous enzymes involved in various biochemical processes. One of its key functions is in the immune system, where it contributes to the development and function of immune cells, enhancing the body’s response to infections and inflammation. Additionally, zinc is important for proper wound healing; it helps maintain skin integrity and cellular repair, facilitating the healing process of cuts and abrasions.

While the other options mention important bodily functions, they do not accurately encompass the primary role of zinc. Energy production, fat digestion, and blood sugar regulation involve other vitamins and minerals that have more direct responsibilities in those areas. Zinc’s specific involvement in immune support and healing makes it a critical nutrient for these processes.
