@ruki the first and most helpful nutritionist I had was part of my local healthcare system (Park Nicollet/Health Partners in Twin Cities, MN). She was diabetic herself and was well versed in renal nutrition. My nephrologist told me that I should “eat for the labs”. By this he means things like potassium, calcium, sodium, phosphorus etc. He monitors my labs, blood pressure and medications. My endocrinologist monitors blood sugar and insulin. I have gastroparesis (a complication of diabetes) and was recently diagnosed with diverticulitis. There are opposite dietary recommendations for gastroparesis and diverticulitis. It is a bit of a slippery slope. Basically I avoid sodium; count carbs to calculate insulin bolus & go low carb; avoid saturated & trans fats that lead to high LDL, cholesterol & triglycerides; try to focus on “good” fats (those that raise HDL) and limit protein to the quantity needed for my size. I used to consume too much protein because it was low in carbohydrates. So far so good. When I was at Mayo (Rochester, MN) for pre-transplant (kidney) evaluation the nutritionist concurred that I was on the right track.
