A renal diet is tailored for individuals with kidney disease to help manage their kidney function and reduce the buildup of waste in the blood. It focuses on limiting intake of certain nutrients like sodium, potassium, phosphorus, and protein, as these can strain the kidneys. Foods such as fruits, vegetables, lean proteins, and low-sodium products are encouraged, while processed foods, high-sodium snacks, and high-potassium foods like bananas and potatoes are often restricted. The goal of a renal diet is to maintain a balance of nutrients that supports overall health while minimizing the workload on the kidneys.
