2. Sweet berries
Sweet berries like blueberries, black currants, raspberries, and more are an excellent way to take some of the strain off your kidneys. Because they are so rich in anthocyanins and other antioxidants, they help fight some of the free radical impurities your kidneys would otherwise be left to clean up.
These tart and delicious berries are packed with antioxidants that fight harmful free radicals and protect your kidneys. Consuming cranberries can actually help your kidneys do their job better by helping your body produce more uric acid. Cranberries also help prevent the buildup of bacteria within the bladder. Cranberry juice is also a good option. However, it is important to make sure that it is 100 percent pure cranberry juice. Just juice and water, nothing else. If it is one of the brands that has sugar, or even worse — high fructose corn syrup — it will negate any benefits you get from drinking it.
