Studies done by Prof. Allan Rodgers at the University of Cape Town scientifically prove that cranberry juice is an effective cure - not only a tasty folk remedy. The reason? The juice alters three key urinary risk factors: it lowers the concentration of oxalate and phosphate, it increases the citrate concentration and it dilutes the concentration of calcium oxalate in the urine. These results were published in the British Journal of Urology.
Previous studies had shown high concentrations of oxalate and calcium oxalate in the urine to contribute to crystal formation. It was also shown that citrate inhibits the formation of crystals - therefore the higher the citrate concentration in the urine, the better.
