Being a patient of 1st stage Kidney disease I must admit that the book "Art of Living with Kidney Disease" which I acquired from Nephrocare India has indeed been helpful for me
The dietician team claimed it had 75 varieties of recipes for renal patients. Since then the book- "Art of Cooking" has become my everyday mate. It has also reduced my wife's tension about what is to be cooked for me regularly.
My potassium level was crossing the borderline. I was worried as high potassium can be fatal, and that's when I was suggested the "Low Potassium Book". By God's grace, my potassium count is normal since then.
