Insects, the new food?

In many parts of the world it is common to eat insects while in the western world it is regarded as a bizarre habit, even evoking disgust. Is this justified? What if insects were nutritionally similar to our common meat products and have proven to be delicious in blind tests? Insects have an environmental impact which is much less than our common production animals, so why not eat it? If these questions can be answered affirmatively, then the question is: Can we persuade the western consumers to take this psychological barrier? There has been a tremendous interest during the last five years to promote insects as food. There are now close to 200 start-up companies listed. Also, in the scientific world the interest is growing exponentially, testified by the number of articles on edible insects that have appeared during the last 15 years (83 from 2011 to 2015 against 9 from 2001 to 20051). These articles deal with harvesting from nature, environmental benefits, nutritional value, food safety, processing, and consumer attitudes. I will give a short overview of the developments in these different areas
