When you have kidney disease, your kidneys are no longer working as well as they need to. Changing your diet can help protect your kidneys. It can also help you control other diseases, such as diabetes and high blood pressure, that can makekidney disease worse.
This topic can give you some general ideas about how to follow the diet your doctor or dietitian recommends.
Monitor your calorie intake to make sure you are getting enough calories.
Include vegetarian sources of protein and calorie supplements when needed.
Increase your phosphate binders that may be needed for meals and snacks.
Suggest a lower potassium dialysate for those on dialysis to control potassium levels.
Make sure your dialysis prescription is adjusted as needed for acceptable urea clearances.
Provide resources, recipes and renal education materials specific to your needs.
Vegetarian diets can meet the higher protein needs of a dialysis patient. Protein is made up of chains of amino acids, which are sometimes referred to as “the building blocks of life.” Plant foods contain most of the essential amino acids. Some plant foods, such as soy, are considered as complete protein foods because it provides all the essential amino acids. Some plant protein may lack one or more essential amino acids, but a variety of vegetarian foods combined throughout the day to provide adequate amounts of essential amino acids without consuming meat, eggs or milk. Plant protein can provide adequate protein into your kidney diet.
Protein enriched foods for vegetarians on a kidney diet may include:
Meat analogs (meat substitutes such as soy burgers, tofu, hot dogs and deli slices)
Soy products (tofu, tempeh)
Beans and lentils
Nuts and nut butters
Eggs and egg substitutes
Phosphorus consumption for normal people as well as for people with CKD non-dialysis is 2.7 to 4.6 mg/dL. For CKD dialysis patients the target range is 3.5 to 5.5 mg/dL. Anything more than that must be reduced. Poor maintenance of phosphorus can lead to not only total kidney failure but also to bone diseases and heart troubles. Dairy products, nuts and beans (the main sources of phosphorus) and drinks and beverages like cocoa, cold drinks and beer must be avoided.
