In Defense of Food: An Eater's Manifesto (released internationally as In Defence of Food) is a 2008 book by journalist and activist Michael Pollan. It was number one on the New York Times Non-Fiction Best Seller List for six weeks. The book grew out of Pollan's 2007 essay Unhappy Meals published in the New York Times Magazine. Pollan has also said that he wrote In Defense of Food as a response to people asking him what they should eat after having read his previous book, The Omnivore's Dilemma. In 2015, In Defense of Food was adapted into a television documentary for PBS.
