Food aversions

So pretty much everyday I do lunch with my coworkers. We can usually agree on something and there's no problem. Even if I don't really like a place very much, I'll suck it up and go. Now that I'm pregnant I've been having some food aversions and the places they pick sound awful (these are places I used to eat at, but now make me feel disgusted). I've said something once about it, about how now that I'm pregnant burgers sound awful, and was basically just told it's not all about me. I still want to go to lunch and socialize with them, but I think I may have to quit going if this is how it's gonna be.

And this probably seems like a silly problem, but I really enjoy my lunchtime with them, just don't wanna eat what they pick sometimes ever since I got pregnant. Thoughts?
