You know Michael Pollan from his blockbuster book The Omnivore's Dilemma or his most recent title, Cooked, which was adapted by Netflix as a documentary series. But the celebrity author hasn't always been so obsessed with what people eat. "Before I started writing about food, my focus was really on the human relationship to plants," Michael tells us. "Not only do plants nourish us bodily—they nourish us psychologically.” Now he's researching flora with psychedelic properties for a new book. Part of the project covers recent experimental trials using psilocybin (a compound found in magic mushrooms) to treat cancer patients' anxiety about death. Plus: How much do you know about ayahuasca? And what Amazonian creature did Michael munch on in Brazil?
