If you are invited to a yuppie dinner party, don’t be surprised if you are offered freshly cooked insects as the first course. While the idea of eating fried insects fills most of us with horror, insect-eating is becoming highly fashionable. For example, in the media industry, successful executives are often seen to eat fried or boiled insects from time to time while working at their desks. These safe-to-eat insects can be found and ordered on the Internet. And young people are logging on to exotic food websites and ordering samples of prepared insects to serve at their dinner parties.

One day, insects could be marketed and sold as a food item in supermarkets. According to their fans, they are not only high in protein and low in fat but also very tasty. [22]But until our attitudes to food change fundamentally, it seems that insect-eaters will remain a select few.
