Phosphorus is an essential mineral that makes up around 1% of a person's body weight, most of which is in bones and teeth.

People with chronic kidney disease (CKD) typically have to restrict and monitor their intake of phosphorus. Most refined oils, fruits, vegetables, and refined grains are low in phosphorus. People should avoid eating meat, which typically contain more easily absorbed phosphorus than found in plants. Since meats are restricted in a CKD diet, egg whites can be a good low-phosphorus source of protein. Soymilk may also work.

The National Kidney Foundation cautions people with CKD to avoid preservatives and additives which use phosphorus. Phosphorus is added to a lot of foods, check ingredient labels for anything with the letters PHOS that includes:

• Dicalcium phosphate
• Disodium phosphate
• Monosodium phosphate
• Phosphoric acid
• Sodium hexameta-phosphate
• Trisodium phosphate
• Sodium tripolyphosphate
• Tetrasodium pyrophosphate

The list below is a sample of foods low in phosphorus that are also low in other minerals (sodium, potassium, etc...) typically restricted on a CKD diet.
