Why Do I Need to Follow a Renal Disease Diet?

If you have kidney disease, your kidneys are not filtering your blood as well as they should. This may cause certain nutrients to build up to unhealthy levels. You can ease the load on your kidneys by reducing your intake of these nutrients. This will reduce your risk of kidney-related complications. It may also delay the progression of your disease.

Food Choices on a Renal Disease Diet

On this diet, you will limit or avoid a range of foods. You will need to work with a dietician who specializes in kidney disease. The dietician can create a meal plan that is right for you.


Sodium is found in table salt and many other foods. Most canned and processed foods contain high amounts. When the kidneys are not fully functioning, extra sodium can result in: To decrease your sodium intake:
  • Avoid high-sodium foods and condiments.
  • Do not add salt to foods while cooking or eating.
To add flavor to your food, use herbs and spices. Salt substitutes often contain potassium. You may also need to limit this mineral.


Potassium is found in many fruits and vegetables. It is essential for proper muscle functioning and heart rhythm. When you have kidney failure , potassium can build up in the blood. This causes problems with heart functioning. You will need to limit the amount of potassium you consume each day. Avoid high potassium foods. Examples include potatoes, tomatoes, citrus fruits, avocados, bananas, and dried fruit. You may still be able to eat your favorite high-potassium food if you limit yourself to a very small portion size. Your dietitian can help with this.


Phosphorous is another mineral that needs to be limited on this diet. If phosphorous builds up in the blood, it can draw calcium out of the bones. This causes your bones to weaken. Phosphorous is found in protein-rich foods. Examples include: dairy products, meat, legumes, nuts, and seeds. Whole grains and cola also contain phosphorous. You may still be able to consume these foods, but you will have to limit the amounts.Also, your doctor may have you take a medicine called a phosphate-binder. This soaks up extra phosphorous and then passes it out in your stool.

Milk 1 cup
