A renal diet chart is a diet that helps people with chronic kidney disease (CKD) manage their condition. The diet limits the amount of fluids, sodium, potassium, and phosphorus in the diet. These substances can build up in the blood if the kidneys are not working properly, and can cause health problems.

The amount of each substance that needs to be restricted will vary depending on the individual's kidney function and other health conditions. A registered dietitian can help create a personalized renal diet plan.

Fluids

People with CKD need to limit their fluid intake to help prevent fluid overload. The amount of fluids that can be tolerated will vary, but a general guideline is to drink no more than 2 liters (8 cups) of fluid per day. This includes water, juice, milk, soup, and other beverages.

Sodium

Sodium is a mineral that helps regulate blood pressure. Too much sodium can raise blood pressure and make it harder for the kidneys to function. The recommended daily sodium intake for people with CKD is 2,000 milligrams (mg) or less. This is much lower than the recommended daily intake for healthy adults, which is 2,300 mg.

Potassium

Potassium is a mineral that helps regulate heart rate and blood pressure. Too much potassium can be harmful to people with CKD, as it can build up in the blood and cause irregular heartbeats. The recommended daily potassium intake for people with CKD is 2,000 mg or less.

Phosphorus

Phosphorus is a mineral that is important for building strong bones and teeth. However, too much phosphorus can build up in the blood and damage the kidneys. The recommended daily phosphorus intake for people with CKD is 800 mg or less.

Protein

Protein is an important nutrient for everyone, but it is especially important for people with CKD. Protein helps the body build and repair tissues. However, too much protein can also be harmful to people with CKD, as it can put extra stress on the kidneys. The recommended daily protein intake for people with CKD is 0.8 grams per kilogram of body weight.

Other dietary considerations

In addition to limiting fluids, sodium, potassium, and phosphorus, people with CKD should also pay attention to other aspects of their diet. These include:

Eating plenty of fruits and vegetables, which are low in sodium and potassium and contain important vitamins and minerals.
Choosing lean protein sources, such as fish, chicken, and beans.
Limiting processed foods, which often contain high levels of sodium and phosphorus.
Talking to their doctor or a registered dietitian about taking vitamin and mineral supplements, as people with CKD may not be getting enough of certain nutrients.
Following a renal diet can be challenging, but it is important for people with CKD to do so to help manage their condition and prevent further damage to their kidneys. With careful planning and support from a healthcare team, it is possible to follow a renal diet and still enjoy a healthy and satisfying diet.

Here is a sample renal diet chart for a calorie diet:
