Marta Zaraska is the author of Meathooked: The History and Science of Our 2.5-Million-Years Obsession with Meat, which was just published this year (2016). Marta writes about science and health for some of the most influential and prestigious publications, including Scientific American, The Atlantic, and the Washington Post. And now that she's been published on the Plant Yourself Podcast, I suppose she's reached the height of achievement ;)
