Think:
Would you rather eat healthy food at a fast food place or the other stuff for a month? What would be the consequences (good and bad)?
Now, does this change your opinion when you go to eat at a fast food restaurant?
For me, I'd choose the healthy, vegan food. The good is that I'd be in better health than most people there. The bad is that I like apple pies :( And, when I think about it, I would rather eat healthier food there.
