Insects offer us many benefits, including their use in human and animal nutrition, in medicine. religion, art, and handicrafts. Also, they are efficient recyclers of organic matter and provide a source of economic gain for the poor through their commercialization. Even if insects are considered by developed nations as an emergency and non‐conventional food of low prestige, they are part of the daily diet of the larger part of humanity, that conceive them as a healthy, nutritious and savory meal, constituting sometimes the only significant source of protein of good quality. Up to date we have recorded around 2000 different edible insect species in the world. Because of their high nutritive value and ubiquitous presence, insects present a potential sustainable food source for humans. Once was select suitable species and develop appropriate breeding methods, insects can provide a reliable and sustainable source of high‐quality animal protein.
