Thank you for the links, Wasabi. The thought of hydrofluoric acid inside the human body ... yikes! I did take a little chem & biochem in college.

There are cases of villi destruction in the absence of celiac antibodies. Sometimes this is known to be attributable to an infection, or to use of NSAIDs. But sometimes, the cause just isn't known. I wouldn't be surprised at all if fluoride might contribute.

Best wishes.
