Which nutrient deficiencies can lead to issues in wound healing?

Nutrient deficiencies play a crucial role in the body's ability to heal wounds effectively. Protein, vitamin C, and zinc are particularly important for this process.

Protein is essential for tissue repair and regeneration, as it provides the necessary building blocks (amino acids) for new cell formation. Without adequate protein intake, the body may struggle to synthesize new tissues, which is vital for healing wounds.

Vitamin C is vital for collagen synthesis, a key component of connective tissue that helps to provide structure and support to wounds as they heal. Additionally, vitamin C has antioxidant properties that help reduce oxidative stress, which can impede healing.

Zinc supports various aspects of the immune response, and it is involved in cell division and proliferation. A deficiency in zinc can lead to delayed wound healing due to impaired immune function and reduced collagen synthesis.

In contrast, while iron and folic acid are important for overall health, their deficiencies are more commonly associated with anemia rather than direct impacts on wound healing. Calcium and magnesium deficiencies affect bone health and metabolic processes but are not as directly linked to wound healing as the nutrients mentioned in the correct choice. Fiber and carbohydrate deficiencies, while important for overall nutrition, do not have a direct correlation with the body's wound healing capabilities.
