What is a possible side effect of high-protein diets?

• A. Increased energy
• B. Kidney damage
• C. Improved vision
• D. Increased cholesterol

Answer: (B)

High-protein diets increase the amount of nitrogenous waste the body needs to excrete because amino acids from protein are broken down and produce urea. The kidneys have to filter more waste, so they work harder to clear this load. Over time, this extra demand can stress the kidneys and may contribute to kidney damage or reduced function, especially for people with pre-existing kidney issues or when hydration is insufficient. The other options don’t fit as direct side effects: energy levels, vision, or cholesterol aren’t reliably caused by high protein intake in the way that kidney stress is. Keeping well hydrated can help the kidneys manage the load, but the potential for damage remains a primary concern with excessive protein.
