They are easy to raise since farming insects has a low impact on the environment, and once over any cultural taboos we may have as diners, they are nutritionally valuable.
Tom Heap gets stuck in to a locust stir-fry in Bristol before heading off to the Netherlands to witness the latest cutting-edge research into raising insects where he also tries a mealworm cookie: a biscuit that could potentially deliver a day's protein ration in one hit to famine stricken areas of the world.
He then visits a farm of the future where row upon row of crickets and various pupae are being raised. They are currently destined for pet shops to be used as animal food, but could soon be turning up on a supermarket shelf near you.
