Phosphorus restriction

Why is it important to control phosphorus in my child's diet?

The kidneys help to remove excess phosphorus from your child's body. If his kidneys are not working well, excess phosphorus builds up in his bloodstream and can cause calcium to leave his bones. This can make your child's bones weak and easy to break.

Most children with renal failure need to limit the amount of phosphorus in foods they eat. Your child's physician or dietitian will tell you how much phosphorous your child should have each day.

What foods are high in phosphorus?

The following foods are high in phosphorous and should be restricted if your child has renal failure:

• dairy products, including:
  • milk (all kinds: whole, low-fat, skim, chocolate and buttermilk)
  • cheeses (all except cream cheese)
  • puddings and custards
  • yogurt
  • ice cream
• meats, chicken, turkey, and fish (especially organ meats)
• dried beans and peas, including:
• black-eyes
• field peas
• kidney
• navy
• northern
• pinto
• lima
• nuts (all kinds, including peanut butter)
• seeds, bran and whole grain cereals and breads

How else can my child's phosphorous level be controlled?

Your child's physician may recommend that your child take a "phosphorous binder," such as calcium carbonate. When a phosphorous binder 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 his bones healthy and strong.
