Objective
To investigate the relationship between citrus fruit juices and kidney stone disease (KSD).
Conclusions
Grapefruit juice was identified as a risk factor for stone formation in large epidemiological studies, while orange juice was not associated with an increased risk for KSD. Orange and grapefruit juices had an alkalinizing effect on urine, while lemon juice raised urinary citrate levels but lacked a significant alkalinizing effect.
Critical Appraisal
Published research can offer valuable insights, but a paper’s conclusions may go beyond what its results support. Critical appraisal examines the methods, findings and limitations to clarify what can reasonably be concluded—and what remains uncertain.
