Like many other fruits good for the kidneys, cranberries have a low sodium content. However, cranberries directly improve kidney health. They do this by preventing bacteria from sticking to the lining of the urinary tract, therefore lowering the chances of infection. This is done using phytonutrients, which are abundant in cranberries.
Cranberry is used to produce delicious sauces, which you can use to add a burst of flavor to your food. Cranberries are a great addition to salads and help fight against heart disease and cancer. But it is their aid to the digestive system that makes them stand out from the rest of the food in this list.
