Eat Less Protein: If your urea, your "bun" --blood urea nitrogen, is high, it means your kidneys are damaged or failing. The urea is a waste product of the breakdown of dietary protein or the protein in your own muscles and tissues, so you can lower it by eating exactly the amount of protein they need each day. This may be as low as 0.3 grams of dietary protein per kilogram ideal body weight per day.
