What foods are most popular now, and how has food popularity waxed and waned over time? We looked at the rates of comments on eight faddish foods:

We calculated these by first finding the total number of reviews for each food. Then, we figured out what percentage of those reviews came in each quarterly period since 2007. (That arithmetic allowed us to normalize the data—-otherwise, this thing would be a huge bacon chart and everything would look tiny.) Perhaps the most surprising thing is how much the answers conform to anecdotal evidence from pop culture. Low-carb diets and Portobello burgers were totally a mid-2000’s thing. And sure enough, their popularity was tanking by 2007. Similarly, if you live on the coasts, you’ve probably found more and more restaurants and haute grocery stores touting quinoa. The trend is very recent. Bacon, though? Bacon’s always been popular, though things have accelerated ever since it’s become a full-blown meme.
