Low in calories (44 per cup), high in fiber, and low in sugar. Studies show that the ruby red berries have some of the most potent antioxidants of any common fruits studied. They possess anticancer properties, inhibit the growth of common foodborne pathogens, and contain antibacterial properties to aid in the prevention of urinary tract infections (UTIs). This is accomplished by preventing bacteria from sticking to the lining of the urinary tract. More recently it has been discovered that the same properties help reduce bacterial adhesions to teeth, thus reducing the formation of dental plaque. Recent studies have also revealed that compounds in cranberries stop certain disease-causing bacteria from sticking to the stomach lining, thus helping to prevent ulcers.
