Cambodian deep-fried tarantula, anyone? A chocolate ant wafer or curried cockchafer? Such meals are already popular in many nations, but now the UN is investigating whether we should all munch on the critters.

Curious to taste creepy crawlies, Lewry visited an insect event at the Natural History Museum in London. "The first thing we discover is that we're already eating insects," says Lewry, who points out how chocolate bars contain insect fragments and cans of sweet corn include larvae chunks. "And frozen broccoli? You really, really don't want to know." His verdict at the tasting table? While he liked the nutty fried crickets and subtly sweet waxworm larvae, "my favourite treat is an off-menu item, a scorpion dipped in chocolate and possessing a gentle alcoholic kick."
