Is Slow Food and organic produce an elitist form of status signalling? What's so good about McDonalds?! And why do we need food waste? Food historian Rachel Laudan joins Adam Grubb and Sarah Coles to talk reasons why she thinks many in the ethical and sustainable food movements could use a little historical perspective, and it's a fascinating and provocative discussion. See her critique of the Slow Food movement, and her award winning book 2013's Cuisine and Empire: Cooking in World History for further reading.
