If you have chronic kidney disease (CKD), you should avoid the high-phosphorus foods listed below: Black beans, black-eyed peas, chickpeas, garbanzo beans, kidney beans, lentils, lima beans, navy beans, pinto beans, red beans, refried beans, soybeans, and white beans are all dried beans. They contain large amounts of phosphorus which can lead to calcium loss from your body through your urine. This is especially important if you are already at risk for developing kidney stones. Phosphorus is a major component of bone tissue and helps maintain strong bones. However, too much phosphorus in your body can cause problems with your urinary system and kidneys. Phosphorus comes from food sources such as meat, whole milk products, egg yolks, oil, potatoes, fruit, vegetables, nuts, and supplements. Food sources of phosphorus include meat, whole milk products, egg yolks, oil, potatoes, fruit, vegetables, nuts, and supplements. In people with normal kidney function, the amount of phosphorus in their blood is tightly regulated by their kidneys. If you have CKD, however, your kidneys may not be able to remove this waste product from your body as well as they should. This means that you may put more phosphorus into your bloodstream than it would normally enter. Too much phosphorus in your blood can cause kidney damage or nephrocalcinosis.
