New Phosphorus Pyramid: Today’s Focus on Phosphorus for Kidney Patients

The Phosphorus Pyramid, a new tool for learning about phosphorus control, was created by researchers Claudia D’Alessandro, Giorgina B Piccoli, and Adamasco Cupisti from Italy. This pyramid does not focus on phosphorus content of foods alone. It incorporates the newer focus on phosphorus load–how much phosphorus is retained due to digestion, absorption and removal (by the kidneys, dialysis and/or phosphate binders).

Foods are organized on different levels based on phosphorus content, protein to phosphorus ratio, and the amount of phosphorus actually absorbed when the food is eaten (bio-availability). The colors from green to yellow to red are a visual guide on which foods are unrestricted, limited and those to be avoided as much as possible.

The pyramid incorporates phosphorus control measures including avoidance of phosphate additives, attention to the amount and source of protein and phosphorus in foods, and preparation method.
