Hi Sanjay. Welcome.
Unfortunately, Mark can't possibly read all the posts here. You can write to him through the Contact button on the home page. But he makes it clear that he won't answer medical questions. However, there are many of us with diabetes and kidney problems. (Neither is serious in my case, thankfully.) Search for "diabetes kidney." You will get a zillion posts to read.
Primal does help diabetes. That in turn should help the kidneys.
