These are quicky easy overviews about zonulin~ People with celiac disease, diabetes, MS, and other autoimmune disease seem to have higher levels of zonulin... which regulate the intestinal and brain blood barriers, are "gatekeeper" to the gut and brain... causing "leaky gut" and "leaky brain"... leaving one more open to problems caused by abnormal immune responses to food proteins that have
escaped those barriers. This is a relatively recent discovery by celiac expert Dr. A. Fasano.
