Research has shown that the ingredients of cranberry fruits destroy Helicobacter pylori bacteria, the most common cause of stomach ulcers. The most important role of cranberry is in preventing recurrent infections of the urinary tract, since the ingredients of cranberry prevent bacteria from attaching to the walls of the canal and bladder, so they are expelled from the body by urination. It is a hard, red berry that, thanks to the higher amount of vitamin C in its composition, has a sour taste. Cranberry fruits, in addition, contain Vitamin A, potassium, calcium, plant fibers and biflavonoids with a strong antioxidant effect, which increase the general resistance of the body and reduce the risk of cancer.
