I was definitely alive at the time and remember no such moral panic. I remember how much more acceptable it was in the 80's and 90's, even in upper middle class families to have 'tv dinners' and I think even for a time in the 70's and earlier (though I wasn't alive) dining out on fast food was a fashionable novelty. I very strongly remember when there was a discernible cultural shift which saw the likes of Whole Foods going mainstream and then the shift after that when even regular grocery stores started to have organic food and in-store bakeries which they didn't have before. And fast food chains started to consciously introduce salads and drop trans-fats and make other changes to seem more healthy. The shift started before Super-size me but I remember how shocking it was and how it helped to define the new zeitgeist that books like Erich Schlosser's Fast Food Nation were also helping to create. I think Super-Size me was even directly responsible for the fast food chains changing their menu part.
