Sodium, Potassium and Protein are usually listed on food nutrition labels, but seldom is Phosphorous. I avoid most prepared foods (like Progresso soups, Lean Cuisine frozen dinners, etc.). No colas, just diet lemon. I miss Fiber One and most Kashi cereals. I assume that processing fiber is hard on those, like myself, who are CKD 4. Strange for me that I need to watch protein intake, whereas those on dialysis need to be sure they get lots of protein. Oh, well.
