4.Cranberry

Cranberries are an awesome fruit to add to most any diet, even a low-potassium kidney diet. They are recommended for people with bladder infections because cranberries contain a type of phytonutrient called A-type proanthocyanidin, which stops bacteria from sticking to the lining of your urinary tract and kidneys. It can be used either in preserved or fluid form to limit kidney difficulties. A study at the University of Maryland Medical Center recommends the use of cranberry to advance kidney function.
