Gluten sensitivity is a known risk factor for recurrent miscarriages. However, until recently we weren’t sure whether it was the gluten itself causing it or the some other factor associated with gluten sensitivity. In this study they investigated the effects of a gluten free diet on recurrent miscarriages and they found that you can greatly reduce your risk of pregnancy loss by avoiding wheat (and all gluten sources) if you have a gluten sensitivity.
