Modifying the diet to avoid foods that irritate the kidneys is crucial to help you function at your best after a diagnosis of kidney disease. Talk to your doctor or nutritionist to get information about what foods will be best to prevent further irritation of your kidneys, then shop for foods carefully to implement the new diet plan proposed by your doctor.
High-Salt Foods
High-salt foods cause problems with kidney function and should be avoided, notes the National Kidney Disease Education Program. Foods that contain high levels of salt include commercial soups, deli cold cuts, and frozen TV dinners. Check the label to check the level of salt or sodium. Ask your doctor for information about how much salt you are allowed each day based on your health issues.
High-Potassium Foods
Foods with high levels of potassium also irritate the kidneys, notes the National Kidney Disease Education Program. Check the labels of commercial foods to ensure they do not contain potassium. You should avoid fruits with high levels of potassium including oranges, prunes, nectarines, raisins and bananas, notes the U.S. Library of Medicine. Also, avoid vegetables that are rich in potassium such as tomatoes, potatoes, spinach, asparagus and pumpkin.
Dairy Foods
Milk, yogurt and cheese should be eaten only in small amounts when kidneys are problematic, notes the U.S. National Library of Medicine. Dairy foods can cause your kidneys to become more irritated. Weaning yourself gradually from dairy products will help maintain kidney health.
High-Protein Foods
Limiting meats in the diet to lower the amount of protein you consume is recommended for patients with chronic kidney disease, notes the U.S. National Library of Medicine. Limiting the intake of beef, chicken, pork and turkey is important when kidneys are irritated. If you begin dialysis, you will then be able to modify the diet to begin eating more high-protein foods.
Kidney Stones
If kidney stones are a problem and your kidneys are irritated, it is best to avoid foods that contain high levels of oxalate. These foods include rhubarb, spinach, wheat germ, beets, Swiss chard, peanuts, chocolate and sweet potatoes, notes the National Institute of Diabetes and Digestive and Kidney Disease.
