Wound repair depends on nutrition to provide the building blocks and energy needed for immune defense and tissue synthesis. Adequate nutrition supplies amino acids for collagen and extracellular matrix, fuels immune cells to prevent infection, and provides the energy required for cell proliferation and remodeling. When nutrition is sufficient, these processes proceed more efficiently, leading to faster and stronger healing. Malnutrition strips the body of essential substrates and energy, impairing collagen production, slowing tissue repair, and increasing infection risk, which delays healing. Hydration supports cellular function but cannot cure wounds on its own, and vitamins are important cofactors, yet they cannot replace the need for adequate protein and calories. So the statement emphasizing that adequate nutrition supports immune function, collagen synthesis, and energy for repair—and that malnutrition impairs healing—best reflects how nutrition influences wound healing.
