Yeah, look. I'd love to see some solid research on this. It's something I hear quite often in defence of meat / against vegan diets, but I'm never shown the why or how of it.

I guess it then comes down to the age old 'minimize harm' element of veganism; i.e. I wouldn't watch the bugs because I get plenty of protein in my diet already. If for some reason other people didn't have access to beans, but did to bugs, then sure, I guess.
