Most of the developing world already eats insects. They are high in protein, B vitamins, and they are low-fat. Their taste is nutty. Insects need less feed than beef or pork and produce less waste. What's not to love?
Dutch entomologists started promoting insects as food in the 1990's. This year their festival, "Wageningen--City of Insects," attracted 20,000 visitors. It's possible that one day in the not-too-distant future, crispy crickets will be as popular as sushi or kiwis. After all, both kiwis and sushi have been relatively new additions to the Western menu.
