This is a very interesting thread. A lot of patients talk about the counterintuitive aspect of the renal diet - white bread instead of wheat bread, white rice instead of brown rice, and a restriction on fruits and veggies. Even though these foods are considered “healthy” for the regualr population, they are not so healthy for people with kidney problems. The level of restriction, of course, depends on each patient’s individual lab results. Rye bread is can be an acceptable substitute for wheat bread and is a nice alternative to white bread.
Legumes and beans can be kind of tricky because they contain both potassium AND phosphorus. Some studies have shown that vegetarian protein sources such as beans and tofu are safer for the kidneys than animal protein. I think choosing a variety of foods that are reasonable in terms of potassium and phosphorus is a good principle to follow. Go for both meat and vegetarian meals. Follow-up with your renal dietitian to make sure you are staying on track.
I know it is not an easy diet to follow. Your commitment and interest in learning are really important. Keep up the good work!
