Follow Your Renal Diet Restrictions For A PreDialysis Diet

Kidney Diet Helps with Planning MealsControl Kidney Disease with Renal Diet Restrictions

Kidneys are the major filtration organs and they remove electrolytes, excess fluids and wastes from your body effectively.  Kidney disease endangers the smooth functioning of kidneys. Following a renal diet is a nutrition therapy and it is highly beneficial for people with kidney diseases to follow the renal diet restrictions to meet the needs of their body. Renal diet restrictions are helpful for reducing the amount of stress put on kidneys. It is also effective for preventing electrolyte disturbances and fluid through correct meal plans.

Importance of Renal Diet Restrictions

Patients with chronic kidney disease must make some changes in their diet to maintain a balance of fluid, minerals and electrolytes. This is helpful for restricting salt, phosphorous, potassium, and protein as well as and getting enough calories. Diet change is inevitable if you need to be put on dialysis, and by following the renal diet restrictions during the period prior to dialysis. Waste products cannot be expelled completely with dialysis alone. Most of the dialysis patients urinate very little. This leads to the building up of excess fluid in lungs, heart and ankles. Therefore, a pre-dialysis diet is inevitable for removing waste products effectively from your body. At the same time, renal diet restrictions should not affect your health adversely. If you do not consume enough calories daily, it may leads to breakdown of body tissues, because your body needs the correct balance of protein and other components.

Foods In Renal Diet Restrictions Help with Pre-Dialysis Diet Needs


Kidneys are responsible for removing excess fluids from blood and excrete it through urine. Kidneys fail to remove fluids properly if they are damaged. It leads to the accumulation of fluids in your body and causes increased blood pressure and tissue swelling. Renal diet restrictions help to reduce the intake of daily fluid to meet your needs but not too much to cause problems. You should closely follow any fluid restrictions that your doctor or dietitian gives you and make sure that you know what foods are considered fluid.


Though carbohydrates provide energy, the consumption of foods with high carbohydrates is not good for people who are overweight or have diabetes. Your pre-dialysis diet must contain less protein than you probably are used to and you may be tempted to fill up on carbohydrates. So, you should include more unprocessed vegetables, grains, breads and fruits in your diet. It is helpful for providing energy, vitamins, minerals and fiber in your body.  The less these foods are processed, the more they retain the valuable nutrients of vitamins, minerals and fiber that are important in a renal diet with restrictions.


Restriction of protein intake is essential for avoiding the creation of urea, a waste product. If there is urea in your body, kidneys need to work hard to expel it. If you have kidney disease, this extra work can further worsens the functioning of your kidneys. At the same time, protein is essential for building body muscles, repairing tissues and fighting infections. So you should not reduce the consumption of protein too much. It should be dependent on your condition and circumstances. A dietitian can help you to include the right balance of protein in your pre-dialysis diet. Protein content is very high in foods such as eggs, pork, poultry, fish, etc.  Most people following a predialysis diet consume between 45-75 gm per day of protein.


You should also monitor the level of phosphorous in your food very closely if you have kidney disease. If the level of phosphorous in your body is too high, it causes low calcium and itching. Due to the low level of calcium, body begins to pull calcium from your bones and it ultimately leads to weakened and brittle bones. Therefore, the foods such as cheese, yogurt and milk should be limited. Some dairy foods such as cream cheese, butter, tub margarine, sherbet, brie cheese, ricotta cheese, etc contain very low phosphorous. Lots of fruits and vegetables should be included in your pre-dialysis diet as per the directions of a dietitian.


Maintaining the balance of electrolytes, such as potassium, sodium and phosphorous,  is the other important function of kidneys. Improper functioning of kidneys cause disruption in electrolytes. Blood pressure increases tremendously due to the increased level of sodium in the diet. Fruits such as peaches, watermelon, tangerines, plums, pineapple, berries, apples, cherries, pears, grapes, and vegetables such as broccoli, peppers, onions, lettuce, green and wax beans, eggplant, cucumber, celery, cauliflower, carrots, cabbage, etc can be included in your pre-dialysis diet. However, your dietitian can prescribe a renal diet, which restricts the intake of electrolytes effectively.


Intake of enough calories is essential for maintaining body weight and its normal functioning. Protein is restricted in renal diet, so it is difficult to meet the calorie needs of the body. In order to ensure enough calories in your pre-dialysis diet, your dietitian can recommend sources of concentrated calories that don’t have too much protein and meet your renal diet restrictions. It includes unsaturated fats such as vegetable oil, canola oil, hard candy, honey, jelly, etc.

You can control kidney disease effectively if you strictly follow renal diet restrictions, dialysis and medication. Usage of alcohol and cigarettes must be avoided or reduced. Consult a doctor or dietitian for getting to the right pre-dialysis diet plan to meet your renal diet restrictions.
