Cranberries are super foods for the urinary tract, and now there's another good reason to eat them: They help fight cancer!
I never drink the Ocean Spray kind, or anything labeled "Cranberry Juice Cocktail" since it's full of GMO corn syrup. Instead, I buy natural 100% pure cranberry juice in bottles from Trader Joe's.
Plain cranberry juice is way too tart and concentrated to drink straight, so I fill a pitcher about 1/5 full of cranberry juice and fill it the rest of the way with water. It turns the water a pleasant pink color, and it's super refreshing.
If you're a wimp when it comes to sour flavors, you can add a little stevia or other healthy sweetener to make it more palatable. But before you give into that sweet tooth, try making it super diluted by using half as much cranberry, and work your way up to liking it stronger, unsweetened.
