Nutrition significantly affects the healing process by providing essential nutrients that support tissue repair and immune function. Adequate intake of macronutrients, especially proteins and carbohydrates, is crucial for muscle synthesis and energy replenishment. Micronutrients like vitamins A, C, and E, as well as minerals such as zinc, play important roles in immune response and collagen formation, enhancing recovery from injuries. Proper hydration also supports cellular function and nutrient transport. A well-balanced diet can accelerate healing, reduce complications, and improve overall recovery outcomes.
