Why don’t we eat insects? What archaeology can tell us about the future of food
When we talk about the foods of the future, insects regularly appear on the list. They are increasingly discussed as an alternative source of protein that could form part of more sustainable food systems. But there’s something slightly odd about calling insects 'alternative' protein - humans have been eating them for thousands of years! In my new paper, Edible insects as heritage foods: towards an archaeology of alternative proteins for food sustainability , published in World Archaeology , I explore what archaeology can tell us about the long history of eating insects, and what that history might contribute to current debates about sustainable food. The archaeological evidence is surprisingly diverse. We can find insects directly in human coprolites, preserved faeces that contain remnants of foods that people actually consumed. At Paisley Caves in Oregon, for example, coprolites dating to the Younger Dryas and early Holocene contain evidence for the consumption of Jerusalem cr...
