GAPS Diet: Gut and Psychology Syndrome

10. Scientific Evidence

There is no medical evidence to back up any of the claims that the GAPS diet is effective at treating autism or any other disorders Dr. Campbell claims. There are no published studies about its efficacy, and Dr. Campbell herself has not published research in reputable medical journals. That said, there is plenty of anecdotal evidence from people claiming the diet has worked for them. It is best to consult with a physician before making any significant changes to your diet.
