A renal diet restricts which nutrients?

• A. Carbohydrates, minerals
• B. Fats and sugars
• C. Vitamin C and calcium
• D. Protein, sodium, potassium, and fluids

Answer: (D)

In a renal diet, the focus is on substances the kidneys struggle to manage and on controlling fluid balance. The main nutrients to limit are protein, sodium, potassium, and fluids. Protein restriction reduces nitrogenous waste like urea that builds up when kidney function is impaired. Sodium restriction helps prevent fluid retention and high blood pressure. Potassium restriction lowers the risk of dangerous heart rhythm changes that can occur when potassium accumulates with reduced renal excretion. Fluid restriction is used to prevent edema and volume overload, especially when urine output is low or variable. Carbohydrates and fats aren’t specifically restricted for kidney function, and vitamin C and calcium aren’t inherently limited on a renal plan ( phosphorus is a common consideration but not part of this option). So the best choice targets protein, sodium, potassium, and fluids.
