Preserve kidney function through limiting protein to how many g/kg/day?

0.6-0.8 g/kg/day 0.8-1.0 g/kg/day 1.2-1.5 g/kg/day 1.5-2.0 g/kg/day

Correct Answer:

0.8-1.0 g/kg/day

Explanation:

In kidney disease, limiting protein helps reduce the kidneys’ workload and the production of nitrogenous waste, which can slow progression and preserve function. The best-supported target is about 0.8 to 1.0 g of protein per kilogram of body weight each day, a level that lowers renal stress while still meeting most essential nutritional needs. Lowering to 0.6–0.8 g/kg/day can risk protein malnutrition if energy intake isn’t carefully managed, while higher intakes like 1.2–1.5 or 1.5–2.0 g/kg/day increase the kidneys’ workload and are not typically used for preservation of function.
