That's the title of an article by Mary Eberstadt from a couple years ago in the Hoover Institution's Policy Review. I found the whole thing fascinating. In the piece, Mary describes the complete reversals that have happened with food and sex. Over the past half century, sex has become much more liberalized, and much that was taboo is now o.k. Precisely the opposite has happened with food.
Here's one interesting sentence
“In the end, it is hard to avoid the conclusion that the rules being drawn around food receive some force from the fact that people are uncomfortable with how far the sexual revolution has gone — and not knowing what to do about it, they turn for increasing consolation to mining morality out of what they eat.”
