Calluses a Gluten Connection?

I was attending a panel discussion at an industry event. A researcher from Finland showed a study connection calluses on feet, knees, hands, and elbows to people having gluten intolerance. The speaker did not offer any solutions other than avoiding gluten.

What was particularly interesting is that she did point out that it was a manifestation that covered those people with mild gluten intolerances as well as those with full-blown celiac disease. I asked her if there was a Psoriasis connection and she said there was, but not enough detail was available.

We have noted that both our Tortuga lotion and MetaCare have a semi-fast-acting effect on calluses and Psoriasis. We have seen and heard from our customers that eliminating gluten has reversed calluses. Initially, we thought that it was just the Tortuga or MetaCare. Now, we are wondering.

Any thoughts?
