Most children with kidney (renal) failure need to limit the amount of phosphorus in foods they eat. The kidneys help remove excess phosphorus from your child's body. If the kidneys are not working well, excess phosphorus builds up in the blood and can cause calcium to leave the bones. This can make your child's bones weak and easy to break.
The following foods are high in phosphorous and should be restricted if your child has kidney failure. Your child's healthcare provider or dietitian will tell you how much phosphorous your child can have each day.
Dairy products, including:
Milk (all kinds: whole, low-fat, skim, chocolate, and buttermilk)
Cheeses (all except cream cheese)
Puddings and custards
Meats, chicken, turkey, fish, and organ meats
Dried beans and peas, including:
Nuts (all kinds and peanut butter)
Seeds, bran, and whole-grain cereals and breads
Your child's healthcare provider may advise that your child take a phosphorus binder, such as calcium carbonate. When calcium is taken with meals and snacks it prevents the phosphorus in foods from being absorbed by the body. This will help keep your child's blood level of phosphorus at an acceptable level and help keep their bones healthy and strong. Be sure your child always takes their phosphorus binder as prescribed.
