Hey guys, thank you for your input. The sentence “what you want to be known as the expert for” kept me thinking the whole night (it was too hot here to sleep anyway)… 😉
I think I would narrow myself too much with just going the gluten free/celiac route. The topics aren’t endless, whereas with allergies/food intolerances/celiac I feel there is so much more I can teach – to more people. Like you, Mark, I would have to do a bit of research from time to time, but I am ok with that.
So thanks again, this was a huge help!
