Orange juice, researchers found, boosted the levels of citrate in the urine and reduced the crystallization of uric acid and calcium oxalate — the most frequently found ingredient in kidney stones.

But lemonade did not increase the levels of citrate, an important acid neutralizer and inhibitor of kidney stone formation.

"One reason might be the different constituents of various beverages," Dr. Odvina said.

For instance, the citrate in orange and grapefruit juice is accompanied by a potassium ion while the citrate in lemonade and cranberry juice is accompanied by a hydrogen ion. Ions of hydrogen, but not potassium, counteract the beneficial effects of the high citrate content.
