This is the most educational video I have ever seen on celiac and gluten intolerance. It starts out very basic, then gets in-depth about what is actually going on in the body and why. Then it goes into the history of celiac. I had never heard the history elsewhere, so trust it if you want.
Showing this video would be a great way to explain celiac to someone. Even when I tell people what it means to be gluten intolerant, I can’t get the idea across this well.
