High-protein diets can have potential effects on kidney health, especially for individuals with preexisting kidney conditions. While protein is essential for muscle repair and overall health, excessive intake may strain the kidneys, as they are responsible for filtering waste products from protein metabolism. For healthy individuals, a high-protein diet is generally safe; however, those with kidney disease may need to monitor their protein consumption carefully to avoid further damage. It is important to consult with healthcare professionals before making significant dietary changes, particularly for those with existing health concerns.
