Am in stage 3 CKD and living with an atrophied left kidney and a 37 % functioning right kidney and am on a renal vegetarian "sorta" diabetic diet. It's been an adventure creating kidney-friendly, diabetic-friendly meatless meals that are tasty and filling but the adventure has improved my kidney function from 28 % to 37 % within nine months. All the info I have says either to avoid whole grains or limit them, which I can't do 100% and stay on a reasonably low carb diabetic diet. What a challenge, eh?
