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.
People with kidney disease have a higher incidence of urinary tract infections, and cranberries are a useful addition to their daily diet because they are also low in sodium, phosphorus, and of course, potassium.
Eating cranberries regularly, whether or not you have kidney disease, can prevent urinary and bladder infections all together. Enjoy them whole, dried, or juiced.
