Low-Phosphorous Diet

What Is Phosphorous?

Phosphorous is a mineral found in food and our bones. Phosphorous has many functions in the body, including helping to build strong and healthy bones.

Why Should I Follow a Low-Phosphorous Diet?

A low-phosphorous diet may be necessary if you have kidney disease. The kidneys help to filter phosphorous out of the blood. If the kidneys are not functioning properly, phosphorous levels can build up in your blood. Your body’s response is to lower these levels by drawing calcium from your bones. In turn, your bones are weakened. This puts you at greater risk for fractures .

Food Choices on a Low-Phosphorous Diet

Phosphorous is found in protein-rich foods. Examples include dairy products, meat, legumes, nuts, and seeds, as well as whole grains, chocolate, and cola.

Suggestions on Eating a Low-Phosphorous Diet

  • Use nondairy creamers in place of milk in your coffee, tea, sauces, and cereal.
  • In addition to choosing foods low in phosphorous, you may need to take medicine called a phosphate-binder. Phosphate-binders soak up extra phosphorous so that it passes out in your stool.
  • Read food labels to track your phosphorous intake. Look for products with 5% or less of the Daily Value (DV) for phosphorous.
  • Work with a dietitian to develop an individualized eating plan.
