Phosphorus is found in many foods. Healthy kidneys remove the extra, but dialysis only removes part of it. Over time, high phosphorus can weaken bones and harden blood vessels.
Phosphorus content of common foods mg per 100 g
Main sources of phosphorus
- Dairy products: milk, cheese, yoghurt
- Processed meats, ready meals and fast food
- Cola drinks and some soft drinks
- Nuts, seeds and chocolate
- Processed cheese and baked goods with phosphate additives
Hidden phosphates
Phosphate additives in processed food are absorbed much more than natural phosphorus. On ingredient lists, look for words containing "phos" (for example E338 to E341 and E450 to E452).
Taking your binders
Phosphate binders work only when taken with food. Take them at the start of each meal or snack, as prescribed, including on holiday when meals are bigger and later than usual.
