Michael Pollan's books 'Omnivore's Dilemma', 'In Defense of Food', 'Food Rules' and 'Cooked' gained huge popularity, especially amongst whole food proponents, after their release in the early 2000s and early 2010s, introducing the idea that we had been eating all wrong. The famous slogan, "Eat food, not too much, mostly plants" also came from Michael Pollan's book.
