The eating of insects, or entomophagy, is not a new concept. In fact, insects have been eaten around the world since prehistoric times.
A history of insect consumption
Stable carbon isotope analysis of the bones and dental enamel of australopithecines, for example, has shown that they were significantly enriched in isotope 13C, suggesting that the diet of these people was largely composed of animals feeding on grasses, including insects. Termites are reported to have been included into the Plio-Pleistocene hominin diet, and an analysis of fossils from caves in the USA and Mexico showed that coprolites from caves in Mexico contained ants, beetle larvae, lice, ticks and mites, providing further evidence for entomophagy in human history.
