Ask everyone ahead of time for ideas on what you should get so you have an idea of what the minority would be interested in.

If you already know in advance, yeah, I think bringing in an alternative so that no one is left out is the classy way to go. Or if there's no time or budget for a second set, it's a nice gesture to find out something the minority would prefer and do that the next time. But if it becomes too expensive or difficult to find some things that a bunch of picky people can agree upon, or the exclusion would cause problems among the group, well, I just might go #3- don't bother.

EDIT: Actually, I'm often among the minority that doesn't like/want certain snack foods people try to share with me. I sometimes worry the person will be offended if I don't try their food or tell them I don't like/want whatever it is. Sometimes I just hope they won't make a big deal out of me not taking whatever it is, and since I don't want it anyway I don't really feel like I'm missing out if someone brings something I don't want. So depending on the personality it might be a non-issue in a casual setting anyway. Just thought I'd throw that out there.

If you know for certain that Julie is allergic to peanuts but you made a glorious peanut butter pie, then yeah, get her something on the side.

But only if you know of something she likes. I dunno, sometimes people with allergies are annoying.

(I say this being allergic to meat)

Is that why you have the personality of a carrot with road rage?

I suppose it would depend on how many people are bringing food items. If there's 12 people and everyone's bringing something little, it's not going make a difference if the few can't have your peanutbutter and oyster sauce sandwiches on honey wheat bread. If there's only a few people bringing stuff though, then absolutely bring a little something on the side.

I don't think I'm much of a carrot. I think I'm more a radish.

If someone has an allergy, I would probably avoid bringing the food altogether, unless I know they can be in the room without dying. I know many nut allergies can be very severe where they could just smell the food and start to go into antiepileptic shock. I would probably bring a small something for them to eat if I brought two things or just bring a general food that everyone likes and enjoys, without negatively affecting the other two people.
I've always been too nice when bringing stuff for people anyways so I usually end up overpaying too much for group gatherings. "Katy likes Coke but Selene likes Pepsi, and I know how much Ben likes apple pie, so many as well also buy a cheesecake."
