Renal diet for vegetarians: Choosing the right proteins

Because I have end-stage kidney failure, I must follow a special renal diet. However, I am a vegetarian. What are the best sources of protein for someone like me who also needs to limit phosphorus and potassium?

Answer

The answer depends on what type of vegetarian you are. Following a proper renal diet is extremely important in treating chronic kidney failure. Research shows that a carefully planned vegetarian diet — or even part-time vegetarian eating — is not only safe but beneficial in managing chronic kidney failure.

Although a renal diet restricts protein, you still need to eat some protein every day — while also limiting sodium, phosphorus and potassium. The chart below lists the best protein sources according to which type of vegetarian diet you follow. If you're a lacto-ovo vegetarian, you can also consider the vegan protein sources. If you're a pesco-vegetarian, you can consider vegan and lacto-ovo vegetarian protein sources, and so on.

Diets for kidney failure are tailored to the individual. Figuring out what to eat and what not to eat can be tricky. Ask your doctor to refer you to a dietitian who specializes in nutrition for people with chronic kidney disease. A dietitian can help you plan meals that fit your habits and preferences but also provide the nutrition you need and avoid or limit foods that can cause problems.
