Hey, I don’t know about other Christian churches but I know that my church SDA has a couple books on it, and I once read a rastafarian book that mentioned it.
I don’t have any money to donate but you might want to checkout getting sponsorships from various denominations with strong health messages, get as many as you can because otherwise people will think you’re biased (it’s funny how some Christians view other Christian just because they go to church farther down the road).
Good luck, I wish I could offer more than advice.
