Protein: Needed for cell growth and repair, protein is crucial throughout wound healing. Amino acids, the building blocks of protein, help make new tissue and repair damaged cells. High-protein foods include lean meats, fish, dairy, legumes, and nuts.

Vitamin C: Vital for collagen formation, a protein that gives skin strength and structure. Vitamin C also has antioxidant properties to protect cells from damage. Sources include citrus fruits, strawberries, bell peppers, and broccoli.

Vitamin A: Important for cell growth and immune function, vitamin A helps form new skin and other tissues. Foods rich in vitamin A include carrots, sweet potatoes, and dark leafy greens.

Zinc: Essential for DNA synthesis, cell division, and protein synthesis, all important for wound healing. Zinc also supports the immune system, reducing infection risk. Good sources of zinc include meat, shellfish, beans, and seeds.

Iron: Necessary for oxygen transport in the blood. Adequate oxygenation is essential for energy production and cell function during wound healing. Iron-rich foods include red meat, poultry, fish, lentils, and spinach.

Vitamin E: Has antioxidant properties that help protect cells from damage during healing. Nuts, seeds, and green leafy vegetables are excellent sources of vitamin E.

Arginine and Glutamine: These amino acids support immune function and collagen synthesis. Arginine promotes blood flow to the wound site, while glutamine supports the immune response. Both are found in meat, dairy, and nuts.
