Na is sodium, K stands for potassium, P is for phosphorus. Other abbreviations and other info can be found in my free recipe collections in several kidney disease support threads here. Please know some values have changed since I first shared my recipes. Also, just to clarify, technically I am no longer a vegan since I needed to add free-range eggs to my renal diet for the protein. Since I am currently "under the weather," I can't answer more fully but the moderator in this thread can guide you to other pages with answers to your questions. Peace and blessings!
