My husband has just been diagnosed with stage 4 renal failure. His kidney function is at 25% and we want to do all that we can to help keep it from going any lower. I am struggling with how to adjust our diet and am seeing lots of conflicting information online. He is also diabetic. Is there a reliable resource to turn to for the best information on the foods he needs to avoid? We don’t see his doctor for another month and I refuse to wait that long to change what he is putting into his body. Any information would be greatly appreciated.

For Stage 4 chronic kidney disease (CKD), I recommend a low salt diabetic diet.  Further dietary adjustments have to be made by your husband’s physician or a dietitian based on the results of the blood testing that has been done on your husband.  I recommend that sodium in the diet be restricted to less than 2300 milligrams per day.  I cannot make other dietary recommendations without reviewing your husband’s history and and laboratory testing.
