We tried the bug-filled ice-cream that The Economist says is the future of food - here's the verdict

Feeding the world's growing population is a challenge - there will be 11 billion of us by the end of the century.

The problem is compounded by the effects of climate change. More extreme weather that results from global warming, like heavy rains and heat waves, threatens the global food supply.

Scientists have suggested for a while that we eat bugs as one way to solve looming food shortages. The Economist also made the case for bugs as a source of cheap and easy protein in an article last year.

Bugs are full of protein, calcium, and fibre, cheap to raise, and more sustainable than livestock. The major hurdle has been getting people, mainly Western cultures, to eat them.

According to The Economist, "not having to look at the bugs, and emphasising the environmental benefits might make the idea of eating insects a bit more palatable."

So we tried it at a kiosk in Canary Wharf in London - here's the verdict.
