In this week’s podcast with Dr. Alycia Halladay Ross, she discusses two new publications that reported on systematic reviews for nutritional and sensory treatments for ASD. This means the existing research was sorted, summarized, scrutinized and evaluated. The reviews found insufficient evidence to show that any dietary or nutritional therapy was effective, but sufficient evidence that sensory integration therapy helps people with ASD. In light of new data on heavy metals found in baby teeth, it is important to remember that chelation is NOT effective and dangerous. While “insufficient evidence” does not rule out these interventions forever and always, lots more needs to be done in these areas to conduct rigorous experiments that don’t have any major shortcomings so they hold up to scrutiny.
