I've eaten quite a few things with bugs. Mostly powdered and in something else -- cricket bread is quite good and very high protein. Grasshopper too. Even black fly casings can be ground up and added into things (though I wasn't as big a fan).

I think insects are a good option for low cost protein. They can be cultivated vertically, and don't require as many resources as some other proteins. I think they add some nice nutrient diversity to diets trying to limit meat consumption. Plant proteins are great, but you can only eat so many forms of soy before it starts messing with your body.

I hope it catches on more. I think once people see and try products where the bug body isn't as noticeable, they'll get over some of their 'ick' factor.
