Chelation Therapy

Here is an article from the Chicago Sun-Times that distills the basic elements of the chelation therapy debate. A brief snippet:
"A survey by the Autism Research Institute, which promotes alternative therapies, found that 76 percent of parents who have tried chelation say their children improved. That's a higher reported success rate than for any other drug, supplement or special autism diet, the survey found.
But just because parents notice an improvement doesn't necessarily mean chelation is the reason, Leventhal said. It could be because of the expectation effect: Parents believe in the therapy, so they become convinced it works. And Leventhal said children naturally improve as they get older."
