Bread for Dialysis Patients
Does anyone have experience baking bread for a dialysis patient? My grandmother is about to begin dialysis and is on a hemodialysis diet. One of the (many!) restrictions of this diet is to limit whole grains, apparently because of their potassium and phosphorus content. My grandmother is a big fan of whole grain breads, particularly rye bread. For some reason, while the doctor told her to avoid whole grains, he did say she could eat "rye, white, or sourdough" bread.
Clearly we need more bread-baking doctors to give more precise advice, but in the meantime, I was wondering if anyone had any ideas for what might be most appropriate. My grandmother is a beginning bread-baking but has expressed interest in sourdough, so I was planning to bring her some starter and teach her how to make a few sourdough rye recipes. However, I'm not real clear on why whole grains are bad but rye is OK, so I'm not sure what would be most appropriate.
