POLAND (REUTERS) - It's a chocolate cake that might make you feel queasy.

The special ingredient is mealworms - and lots of them.

Wroclaw's University of Environmental and Life Sciences researchers made it as they research future trends in nutrition.

The team says insect farming consumes far less water than crops and can be done at home.

Insects are frozen, then ground up or thrown straight into a frying pan.

Deep-fried crickets taste like roasted chicken, larvae has a nutty flavor, and ants are spicy and slightly sour.

Most importantly, they're all nutritious.

Researchers are searching for alternative solutions to feed the world's growing population.

By 2050, a 70 per cent rise in food production will be needed, with limited agricultural land available.
