Western European populations are being encouraged to reconsider their diets in light of population growth and the intensification of meat production, to meet this growth. Health concerns associated with diets high in sugar, salt and saturated fat are also stimulating interest in alternative foods. Edible insects may be one option to help feed a growing population more sustainably, but this comes with its own challenges. This paper reflects on a pilot project introducing edible insects into primary and secondary schools in Wales, UK. Using Bakhtin’s concept of the carnivalesque as a lens for reflection, the difficulties in introducing a novel food are considered and we provide an insight into how more sustainable, fringe practices may be framed in ways that allow them to be normalised.
