What nutrient deficiency can lead to skin integrity issues in at-risk populations?
Vitamin D
Protein
Folate
Iron
The correct answer is: Protein
Protein is essential for maintaining skin integrity due to its critical role in the synthesis of collagen and elastin, which are structural proteins that provide strength and elasticity to the skin. A deficiency in protein can lead to delayed wound healing, increased risk of pressure ulcers, and overall compromised skin integrity, especially in at-risk populations such as the elderly, malnourished individuals, or those with chronic illnesses. In at-risk populations, adequate protein intake supports immune function and aids in the repair and regeneration of tissues, which is crucial for skin health. When protein levels are insufficient, the body's ability to respond to injury diminishes, making it more susceptible to skin breakdown and complications. This highlights the importance of monitoring protein intake and ensuring that individuals, particularly those vulnerable to skin issues, receive adequate dietary protein for optimal skin health and wound healing.
