..and I've heard mixed reviews, but there's a big CDC double blind, multi-year study that's due to report back some time this year that's been looking at it (how do you do a double blind study on diet, anyone?). I'm waiting to see the results of that. Placebo effect in autistic populations is huge (lots of wishful thinking), so any study that isn't double-blind isn't worth the paper it's printed on IMO.
