Drinking two glasses of cranberry juice a day can ward off flu, stops teeth from rotting and keep away bladder infections and stomach ulcers - but only in women. Researchers have proved that the red berry has anti-viral properties but the healing powers of the fruit only applies to women.
Cranberries contain a molecule called non-dialyzable material, or NDM, which coats some bodily surfaces with a Teflon-like substance and prevents infection-causing agents from taking root. The substance has no effect on the good bacteria.
Back in 1991 researchers found that the berries could protect against bacterial invasion in the bladder - they then decided to see where else the healing properties would work. They discovered that the same substance that prevented urinary infections also stopped oral bacteria forming on the surface of teeth and reduced the cavities formed in the mouth. After the clinical trial the scientists at the Tel Aviv University's medical school patented a mouthwash based on cranberries. They also found that the molecule inhibits the flu virus from attaching to cells and inhibits two-thirds of the 'unhealthy' bacteria that cling to gastric cells, which lead to ulcers.
Professor Itzhak Ofek said: "The results were very interesting. Cranberry helped reduce the load of this bacteria, Helicobacter pylori, in the gut. In combination with antibiotics, it reduced repeat ulcers from approximately 15 per cent to about five per cent."
But Professor Ofek added: "The whole thing with cranberries seems to be female-oriented."
