Renal Diet


A renal diet is a diet that restricts foods which are high in sodium, potassium and phosphorus. The diet is recommended for people with late stages of chronic kidney disease and end-stage kidney disease. The diet attempts to reduce the build-up of micronutrients in the blood in order to prevent, arrhythmias, bone disorders, fluid overload, vascular calcification and hypertension.

The renal diet is restrictive. Foods such as potatoes, orange juice, tomatoes, bananas, dairy products and processed meats should be avoided. Furthermore foods such as orange/ orange juice and avocados also contains a good dose of potassium therefore it’s recommended to be limited and/or avoided.

Wastes in the blood come from food and liquids that are consumed. People with kidney disease must adhere to a renal diet to cut down on the amount of waste in their blood. Following a renal diet may also bolster kidney function and delay total kidney failure.

A renal diet is one that is low in sodium, phosphorous and protein. A renal diet stresses the importance of consuming high-quality protein and limiting fluids. Some renal diets may also call for limited potassium and calcium. Every person is different, and therefore, a dietician will work with each patient to come up with a renal diet that is tailored to his or her needs.

You need to have a kidney-friendly meal plan when you have chronic kidney disease (CKD). Watching what you eat and drink will help you stay healthier. The information in this section is for people who have kidney disease but are not on dialysis.

This information should be used as a basic guide. Everybody is different and everybody has different nutrition needs. Talk to a renal dietician (someone who is an expert in diet and nutrition for people with kidney disease) to find a meal plan that works for you.

Healthy diet basics

With all meal plans, including the kidney-friendly diet, you need to track how much of certain nutrients you take in, such as:

  • Calories
  • Protein
  • Fat
  • Carbohydrates

To make sure you are getting the right amounts of these nutrients, you need to eat and drink the right portion sizes. All of the information you need to keep track of your intake is on the “Nutrition Facts” label.
