I think insects are quite tasty, cooked in a variety of ways. I used to bake chocolate chip mealworm cookies for my students. We're vegetarian, though, so I generally don't cook with insects. However, I'm not all that picky about getting all the bugs off the organic vegetables I grow, so we end up eating quite a few. They're a great source of vitamin B, which is only found in animal products, so I reckon it's critical for us to be eating them.
Insects are important components of most human diets--just not the modern Western diet. They're high in protein, low in fat, and provide some important micronutrients that are difficult to get in other ways. Even better, because they're cold-blooded, they convert food to animal protein at a much higher rate than sheep, beef, poultry, etc. They're a much more environmentally responsible source of protein than our usual meats. So I'm fully in support of making insects a part of the Western diet--it would be good for people and good for the planet. If you can't beat 'em, eat 'em!
