Cranberries: scientific studies*

 

Scientific studies show that cranberries anthocyanins have many health benefits, including:

​

  • protecting against bacterial infections in the urinary system and preventing bacterias from seizing into bladder walls (1-6)

  • preventing the formation of alkaline stones in the urinary tract by working against bacterial-infections

  • preventing the development of cavities in teeth in a way similar to the action in preventing urinary tract infections

  • fighting oxydative stress (7)

  • displaying anti-proliferative activity against several types of cancer in vitro and in vivo, including gastric cancer (8) and esophageal adenocarcinoma. (9) 

  • fending off ulcers by preventing helicobacter pylori, the bacterium which causes peptic ulcers, from adhering to the stomach lining. (10,11)

  • lowering bad cholesterol levels and increasing good cholesterol levels in the blood.
