Stage 3 is often when people start searching for a rigid list of foods to eat and avoid. That list can be misleading because nutrition needs depend on labs and the rest of your health picture.
What commonly deserves attention
Sodium is often important for blood pressure and fluid management. Protein should be adequate rather than automatically maximized. Potassium and phosphorus decisions should be guided by labs and professional advice rather than blanket restriction.
Build a useful plan
Bring recent lab results and a typical food diary to a dietitian or healthcare appointment. Read our guides to sodium, potassium, phosphorus and protein.
