Abstract
Insects are frequently promoted as a nutritious food. Yet they are a diverse class, and few data are available on their dietary role. In this paper, we present novel data on the nutritional role of ‘chitoumou’, the edible caterpillarCirina butyrospermi, in the diet of rural smallholder farmers in southwestern Burkina Faso. We collected detailed dietary data via 24-h recall interviews (n=64), which we conducted with women who were predominantly responsible for making decisions on food preparation for their households (n=16) during and out of caterpillar season. We found that ethnicity did not predict caterpillar consumption. Diets that contained caterpillars were richer in protein (P<0.05) and calcium (P<0.05), key nutrients for combating malnutrition in this region. We conclude that edible insects play an important nutritional role among smallholder communities in southwestern Burkina Faso, but that more data are required to confirm the bioavailability of nutrients found in caterpillars, the effect of the cooking process on caterpillar nutritional quality and consequent health outcomes for people that consume them. To inform policy and the way in which insects are promoted as food, it is imperative that further research is done to quantify the nutritional role of edible insects in current human diets.
