I need a list of food and drink that will help me maintain my kidney health. Most of my test results remain in fairly normal range, but my GFR is 39. I would like to maintain this level I have no other complicating factors. My blood pressure is low to normal, I am not diabetic, my cholesterol is perfect, I am not over weight and I exercise regularly. The only problem is one of my kidneys is atrophied and scarred even though I have no UTI history. I have had 4 kidney stone attacks, but are under control now. I cannot pay......Medicare is my only insurance.
