Effect of blackcurrant-, cranberry- and plum juice consumption on risk factors associated with kidney stone formation.
Eur J Clin Nutr. 2002 Oct; 56(10):1020-3.EJ

Abstract

OBJECTIVE

To evaluate the influence of plum-, cranberry- and blackcurrant juice on urinary stone risk factors.

DESIGN

Investigations were carried out in 12 healthy male subjects aged 18-38 y. All subjects received a standardized diet formulated according to the dietary recommendations of the German Society of Nutrition. The subjects provided 24 h urine collections in a control, 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 supersaturation for uric acid were increased. Blackcurrant juice increased the urinary pH and the excretion of citric acid. The excretion of oxalic acid was increased too. All changes were statistically significant. The plum juice had no significant effect on the urinary composition.

CONCLUSION

It is concluded that blackcurrant juice could support the treatment and metaphylaxis of uric acid stone disease because of its alkalizing effect. Since cranberry juice acidifies urine it could be useful in the treatment of brushite and struvite stones as well as urinary tract infection.
