Which nutrient is essential for wound healing?

Zinc is a crucial nutrient for wound healing due to its significant role in the body's immune function, cell proliferation, and protein synthesis, all of which are important processes in the healing of wounds. It plays a vital role in the formation of collagen, a key protein that helps in tissue repair. Additionally, zinc is involved in the inflammatory response and the overall cellular repair process, making it essential for efficient healing.

Vitamin A, while important for maintaining epithelial tissues and enhancing immune function, does not play as direct a role in wound healing as zinc does. Iron is critical for oxygen transport in the body and is important for overall energy and metabolism, but it is not specifically recognized for its direct impact on the healing process. Folate, on the other hand, is necessary for DNA synthesis and cell division, which are important for new tissue formation, but it does not have the same specific role in wound healing as zinc. Hence, zinc stands out as the essential nutrient for wound healing.
