I'm pre dialysis too. This spread sheet just shows mostly foods I myself might eat and has on it the potassium and phosphorous amounts per serving of whatever weight I might have it in like ounces or cup etc.
I've tweaked with it over the years, took off the foods that were what I thought really high in one or the other like Swiss Chard... one cup raw is close to 1,000 mg of potassium. I also took off all the cheeses because the ones I listed are about 1/3 the phosphorus of the other cheeses except Cottage cheese but that's loaded with sodium and I don't care that much for it. Also you will not see nuts, beans and foods that are high in Phosphorous.
I've been saying for years that if it's good for you it's probably not good for me.... I really miss nuts, beans and whole grains
