I think a nice-looking folder containing some some studies would not hurt, or just have them on hand if the conversations turns that way.
My opinion is main stream material would have more appeal than medical studies.
I know a few years back time magazine had a small one page article about Tai Chi as the perfect exercise, not the best article but the title is good and catchy.
Also you could pick out the least desired locations and go in on a test run and see where the conversations go , and this would give you a better idea what would be needed.
Good Luck,
Aaron
