I find the soda thing ridiculous. I mean, if I can't get sugary soda, I make tea - and load it with sugar. The way I see it, I am probably doomed to get diabetes someday, anyway, if I live long enough because I have a genetic predisposition to it. Women in my family get it without fail. I could drink nothing but broccoli juice for the rest of my life and still probably get it. I'm living it up with the sugar and chocolate right now because I know I won't get to have it later.
As far as bans... I'd probably go for banning the things on this list. WARNING - very graphic list article ahead.

The weird thing is, the fois... if I were rich enough to ever try it, I'd probably like it because it comes from duck. I can see myself never trying it even if I become rich because of being haunted by a video I saw of it being raised once... *shiver.*
I'm not a hippie about this, either. I love meat. One of my first memories growing up were "helping" my dad butcher the family chickens and pigs, I read an article on a news site today written by someone freaking out about the poop-content of processed chicken and was going "Eh, doesn't bother me, I've worked with poo." I also fish and process my own catch in the kitchen when successful and can tell you that fish are hard to get killed good and dead... I'll chill them in ice water or brain them with the tip of a knife, but sometimes, when cleaning them, I'll still get a twitch after I was sure I'd fully killed them so I am fully aware of some of the mess involved with animal-derived food, but going out of the way with deliberate cruelty - "It has to suffer to taste good!" is where I shiver at the evil and feel too sick to eat.
As for personally-disliked foods - celery and liqourice can dissapear from the planet as far as I'm concerned. I support other people's enjoyment of them, though. You can have my share.
