Researchers from The University of Cape Town investigated the effect of cranberry juice on kidney stone formation. The first 10 participants drank 500 ml (1/2 liter) cranberry juice diluted with 1500 ml (1.5 liter) water for 2 weeks while the other 10 participants drank only 2 liters of water. At the end of the study scientists concluded that daily drinking of cranberry juice significantly decreases the formation of kidney stones (especially calcium oxalate).
