Your Diet and Chronic Kidney Disease

Limit Phosphorous and Calcium

You need these minerals to keep your bones healthy and strong. When your kidneys are healthy, they remove the phosphorus you don’t need. But if you have CKD, your phosphorous levels can get too high. This puts you at risk for heart disease. What’s more, your calcium levels begin to drop. To make up for it, your body pulls it from your bones. This can make them weak and easier to break.

If you have late-stage CKD, your doctor may advise you take in no more than 1,000 milligrams (mg) of phosphorus mineral each day. You can do this by:

  • Choosing foods with low levels of phosphorous (look for “PHOS” on the label)
  • Eating more fresh fruits and veggies
  • Choosing corn and rice cereals
  • Drinking light-colored sodas
  • Cutting back on meat, poultry, and fish
  • Limiting dairy foods

Foods that are high in calcium also tend to be high in phosphorous. So, your doctor might recommend you cut back on calcium-rich foods. He might tell you to stop taking over-the-counter calcium supplements, too.
