Indication: Kidney stones
Source: Eur J Clin Nutr, 2002;56:1020-1023
Research: Twelve healthy male subjects, ages 18-38, received a standardized diet formulated according to the dietary recommendations of the German Society of Nutrition. The subjects provided 24 hourly urine samples and were divided into a control and three loading phases. In each loading phase a neutral mineral water was substituted for 330 ml of the particular juice.
Results: Cranberry juice decreased the urinary pH, whereas the excretion of oxalic acid and the relative super-saturation for uric acid were increased. In contrast, black currant juice increased the urinary pH, the excretion of citric acid and the excretion of oxalic acid. According to the scientists, all changes were statistically significant. The plum juice had no significant effect on the urinary composition. Researchers concluded that black currant juice could support the treatment and metaphylaxis of uric acid stone disease because of its alkalizing effect. Since cranberry juice acidified urine it could be useful in the treatment of brushite and struvite stones as well as urinary tract infection.
