Kristina--I went vegetarian six or seven weeks ago. It was easier than I thought, although I'm probably not as strict as you. I allow myself a free meal once per week, which usually includes a second helping. I also use protein bars and shakes as long as they're low in the three other restricted ingredients. I haven't had any lab tests yet, but I did lose about ten pounds without even trying. Not that I needed to lose them, but it means that I can eat quantity as well as quality. I'm hoping that a meatless diet arrests or reverses the recent decline in my GFR.
When I was studying the database for protein and phosphorus, I noticed that Garbanzo Beans (or Chickpeas) have more protein-to-phosphorus and less potassium that other beans or peas. When I ran the ratio numbers and then factored in 'absorbability' guidelines, garbanzo beans (canned, washed in water and drained) when combined with something like wheat flatbread is about the same as chicken - a really good source of protein without too much phosphorus or potassium. That makes hummus on crackers a great renal-safe snack, and a sprinkle of garbanzos on salad is a better choice than shredded cheese. .
