— Explanation · 中文詳解 —
組織修復需要足夠的蛋白質來合成膠原蛋白；維生素 C 是膠原蛋白合成的輔因子，也是強效抗氧化劑，能促進傷口癒合與微血管生成。碳水化合物提供能量，但非修復核心；脂肪與礦物質雖需均衡，但蛋白質與維生素 C 的缺乏對傷口癒合的影響最為直接且顯著。
Tissue repair requires sufficient protein for collagen synthesis; vitamin C is a cofactor for collagen synthesis and a potent antioxidant, promoting wound healing and capillary formation. Carbohydrates provide energy but are not the core of repair; fats and minerals are needed in balanced amounts, but deficiencies of protein and vitamin C have the most direct and significant effect on wound healing.
