Gimlet Media has been consistently producing high quality podcasts since their first days with the StartUp Podcast about the founding of the company. Some of my favorite podcasts *coughReplyAllcough* are Gimlet shows. One of their divisions is Gimlet Creative, which lets brands commission high quality narrative content as embedded advertising. I have listened to a few of these and really, several are of really interesting and well done, despite being a glorified commercial.
One of the latest is Why We Eat What We Eat, which explores the cultural reasons we eat what and the way we do (sponsored by Blue Apron, though I am not). The most recent episode explores the climate change diet, and the way our eating habits may evolve as the biosphere does in relation to climate change. In the episode, people commit to eating the obscure and interesting proteins that could become staples of a world that is a handful of degrees warmer than today and chefs work with making some of these things more elevated.
