It's amazing to me how ingrained or trained our food preferences are. At the University of Arizona, the Entomology and Insect Science program used to have a big insect brunch. I liked going because there was always a lot of good food -- and hardly anyone ever ate it. They had some great Cricket California Roll sushi. And the mealworm cookies were great. As a kid, I raised mealworms, crickets, and yes, even wood roaches, to feed my pet snake. Insects are as clean as their environment. As protein, they would be really efficient -- anything that's cold-blooded, like insects or fish, is a lot more efficient than warm-blooded animals that waste energy as body heat.
