protein-calorie malnutrition and deficiency of vitamins A and C and zinc impair normal
wound-healing mechanisms. lf a patient who has a chronic wound also has untreated malnutrition,
the healilg process may be even more difficult. Protein is needed for tissue regeneration and repair.
A protein deficiency can delay wound healing by exacerbating the inflammatory phase of the wound.
There is also a connection between zinc and the body's ability to synthesize protein and collagen,
which is necessary for wound healing. Zinc is essential for cell division and protein synthesis.
Vitamins also play a part in wound healing. One study suggests that vitamin A can benefit
Wound healing by enhancing the early inflammatory phase and increasing the number of
Macrophages at the wound site. it also could improve the stimulation of the immune response.
Vitamin C enhances neutrophil production. increase angiogenesis, acts as antioxidant, and helps in
the production of collagen.
