Why is white bread suggested for the renal diet?

White bread is lower in potassium and phosphate than whole meal bread…

and therefore is recommended for those with reduced kidney function, particularly if your blood levels of potassium and phosphate are high.

so does the kidney’s ability to filter potassium and phosphate.

choose lower potassium and phosphate products like white bread (sliced or rolls), granary bread, ciabatta or white pitta bread.
