In order to get Americans at actually turn to insects as a source of protein and other nutrients, it’s going to take a massive marketing effort and psychological overhaul.

Wendy Lu McGill, an advocate of eating bugs, hailed the amazing benefits of eating insects in this article from NPR. But try as she might, Americans just aren’t budging.

"Crickets have as much calcium as milk," McGill says. "And then, environmentally, they're a lot more sustainable than chickens and particularly cows and pigs."

Several companies have ventured into the market, advertising products such as cricket-based chips called Chirps or grasshopper energy bars called Hopper Bars. There are even efforts to rename locusts “sky prawns” to make them more appetizing.

"There is obviously a hurdle to get over, in terms of the 'yuck factor,'” Jack Ceadel, founder of the Austin, Texas-based Hopper Foods, told NPR. "The key to this is that people don't want to see the actual bug itself. It's the legs and the antennae that scare people.”

Few Americans are buying it though and simply refuse to eat bugs. To most meat-loving Americans, insects belong on the bottom of shoes – not in mouths.
