Which diet is right for you? Wrong question.

Humans didn’t evolve to shop for food that has been collected, packaged with nutritional information, and arranged by category in brightly lit supermarkets. In fact, we didn’t evolve to choose our food at all. 

In his new book, “Fed Up: What Evolution Reveals about Food, Diet, Health, and Eating Well,” Daniel Lieberman, Edwin M. Lerner II Professor of Biological Sciences in the Department of Human Evolutionary Biology, explores how our ancestors evolved to eat almost anything they could hunt, gather, or grow in whatever habitat they happened to find themselves. Which makes the modern American diet’s embarrassment of riches a real conundrum. Should we eat low-carb or low-fat, vegan or strictly animal products?

In “Fed Up,” Lieberman argues that most diets cling too firmly to one “big idea” and that they can, and should be, much more flexible. Lieberman helped us develop this quiz based on the book to help us make sense of it all.
