Kidney stones, hard masses formed in the kidneys that usually consist of insoluble calcium compounds, are on the rise among children and teenagers, according to the Cleveland Clinic. But sipping naturally sweet lemonade, which is rich in citric acid, may help ward off the painful masses, said Dr. Jeffrey Donohoe, a pediatric urologist at Cleveland Clinic Children’s.
[Lemonade] has the stuff that stabilizes stones, but it has a lot less of the stuff that can form stones.
Kidney stones often form when oxalate, a byproduct from some foods, binds with urine. Lemon juice, which is low in oxalate, can stunt the growth of pre-existing stones and prevent crystal deposits in the kidneys from developing into stones. The masses are usually treated with pain relievers like Advil and Tylenol or with prescribed alpha blockers— which relax muscles in the ureter, and help patients pass their kidney stones more rapidly and with less pain.
