Interesting in him but afraid for my health

There’s a guy that I’m interested in but I’ve always had a hard time with dating because of my SEVER wheat allergy. I can’t eat out at all which most people are okay with. However if I was to date someone and they were to eat something and kiss me It would cause a reaction. Would a guy adjust his life style for someone if he really cared?? He doesn’t have to necessarily change diet but very cautious and mindful. I’m in my 20s and this has always held me back and idk what to do about it.
