Gastropod looks at food from the perspective of science and history. The podcast is nicely designed and is produced and presented by Cynthia Graber and Nicola Twilley, who are both journalists with an academic background in the sciences. Witty and stimulating in equal measure and with an archive going back to 2014, there are two episodes a month, each one a mixture of short items and longer in-depth reports. Episodes have covered caffeine, fungi, alcohol consumption, the calorie as a unit of energy and snails. Each podcast comes with notes, and is often accompanied by stills and short videos. The podcasts are available on Soundcloud, iTunes and as RSS feeds.
