Cranberry Juice Creates Energy Barrier That Keeps Bacteria Away From Cells, Study Shows
July 21, 2008
People have long consumed cranberry juice to ward off urinary tract infections, though the exact nature of its action has not been clear. A new study by researchers at Worcester Polytechnic Institute reveals a key mechanism that may help account for its disease-preventing abilities. The juice, the study shows, changes the thermodynamic properties of bacteria, creating an energy barrier that prevents the microorganisms from latching onto cells in the urinary tract.
