The link I find most useful is to Scott Adam's Celiac.com. One can subscribe to their newsletter free of charge and to The Journal of Gluten Sensitivity (fee involved). It covers scientific findings, articles on managing a gluten free lifestyle and recipes.
Dr. Rodney Ford, MD and Professor of Pediatrics writes that he thinks gluten causes brain disease. The brain is significantly affected and gluten is a neurotoxin. I will be writing on this in the near future but in the mean time read this article.
