How OJ Prevents Kidney Stones

It's long been suspected that citrus juice helps prevent kidney stones. But new research shows that not all citrus juices are created equal when it comes to fighting the painful stones, reports WebMD.

According to the report, a kidney stone forms when minerals and other chemicals in urine concentrate into crystals. Eventually, these crystals gather into stones. One way to prevent this is by adding potassium citrate to your diet. Citrate, found naturally in citrus juices, decreases the acidity of urine and makes it hard for the dreaded stones to form.

But not just any citrus juice will do. According to a study published in the Clinical Journal of the American Society of Nephrology, orange juice and grapefruit are the best juices for protecting against kidney stones.

As it turns out, the difference between orange juice and juices like lemon or cranberry is subatomic. One scientist believes the citrate in lemon and cranberry juices includes a proton that "may counteract the acid-lowering affects." OJ on the other hand has a potassium ion which does not.

I started pound360 to channel my obsession with vitamins, running and the five senses. Eventually, I got bored focusing on all that stuff, so I came back from a one month hiatus in May of 2007 (one year after launching Pound360) and broadened my mumblings here to include all science.
