So, for now the best people like me can do is stay far away from gluten. And, actually, the video
is saying to stay away from all grain to be truly
gluten free. Rice
is the safest of all grains, but it does still contain a small portion of the gluten specific to rice. All grains have gluten. The name of the gluten in wheat is gliadin, which of course is the main source of the problem for people, since wheat is so pervasive and in things you don't expect it to be.
