What nutrients are crucial for wound healing in adults?

• A. Fatty acids and sugars
• B. Vitamin D and calcium
• C. Adequate protein, vitamins A and C
• D. Excessive carbohydrates and low water intake

Answer: (C)

The nutrients that are crucial for wound healing in adults include adequate protein, vitamins A and C.

Protein is essential for tissue repair and regeneration because it provides the amino acids necessary for the synthesis of new cells and the formation of collagen, which is a key component of the skin and connective tissue. Adequate protein intake also supports the immune system, which plays a critical role in the healing process by helping to prevent infection.

Vitamins A and C are also vital in wound healing. Vitamin A contributes to the formation of new epithelial cells, which are essential for closing wounds and maintaining skin integrity. It also plays an important role in immune function. Vitamin C is critical for collagen synthesis, which is fundamental for healing, as it helps to stabilize the structure of the protein. Additionally, it has antioxidant properties that protect cells from damage and support the immune response.

In contrast, nutrients like excessive carbohydrates and low water intake can hinder wound healing, as dehydration can impair circulation and nutrient delivery to tissues, and a high carbohydrate intake without protein may not provide the necessary building blocks for repair. Vitamin D and calcium are important for bone health but are not the primary nutrients involved in the wound healing process, and while fatty acids can play a role in inflammation and cell
