Edible insects; you may feel that these two words do not even belong in the same sentence. You have every right to be skeptical. In all probability, you have never deliberately ate an insect. However you have probably inadvertently consumed over a pound of insects in your lifetime.
Your insect consumption adds up. Flour beetles, weevils, and other insect pests that infest granaries are milled along with the grain, finally ending up as tiny black specks in your piece of bread. Small grubs and other tiny insects can be found in your fruit and vegetables. Insects are especially common in canned and other types of processed food, and even in certain beverages; I once went on a tour of an apple orchard and while the group was viewing the area where they separate the rotten and bug infested fruits from the good ones, I asked the tour guide what they did with the bug infested apples. She told me that they use them to make cider; waste not, want not! It is virtually impossible that you have not ingested insects in one form or another during your lifetime. And it probably did not harm you, but instead did you some good by providing extra protein in your meal!
