Why we still don't eat insects: Assessing entomophagy promotion through a diffusion of innovations framework

A Diffusion of Innovations framework is used to review entomophagy, the human consumption of insects, and its promotion. Overemphasis on changing values and unrealistic goals of insects as alternative to meat hampered entomophagy's diffusion. Supply-side developments to fight passive rejection are essential before a majority of consumers will accept insects as food. Marketing insects appropriately or using them as livestock feed will also facilitate diffusion. (C) 2015 Elsevier Ltd. All rights reserved.
