What role does zinc play in renal nutrition?

Zinc plays a significant role in renal nutrition, particularly for individuals with chronic kidney disease (CKD). One of the essential functions of zinc is its involvement in the immune system. Adequate zinc levels are critical for maintaining a robust immune response, which can be particularly important for CKD patients, as they may be at a higher risk of infections and complications. In this population, zinc deficiency is not uncommon due to dietary restrictions, altered metabolism, and increased losses during dialysis.

Supplementation of zinc in CKD patients can help support immune function and overall health. Additionally, maintaining appropriate zinc levels can contribute to the body's healing processes and cellular functions. Thus, the answer highlighting the importance of zinc for immune function and the potential need for supplementation in CKD patients accurately reflects the role of this essential mineral in renal nutrition.
