Insects as sources of proteins for man: Valorization of disgusting resources

Entomophagy or the use of insects as food is analyzed by taking into account the nutritive importance that insects can offer to overcome both hunger and malnutrition in many parts of the world. About 1509 species of edible insects have already been recorded in nearly 3000 ethnic groups distributed in more than 120 countries. The largest group of edible insects is comprised of Coleopterans (443 species), which is followed by Himenopterans (307 species), Orthopterans (235 species), and Lepidopterans (228 species). Studies have shown that the "flesh" of insects contains satisfying amounts of proteins and fats, and they are rich in minerals and vitamins as well. However, the aversion to the edible insects is the reason why a considerable amount of animal protein becomes unavailable since the phenomenon is regarded as "primitive peoples practice". It is necessary to change the ideas we have concerning insects and include them in ordinary meals.
