There's a new diet being pushed by the UN: Eating insects. A food agency in Europe says it could fight hunger, boost nutrition and reduce pollution.

FOX News Radio's Simon Owen reports from London:

The leading contenders include grasshoppers and ants. Rich in protein and minerals and better for the environment than meat like beef because insects eat less and produce less greenhouse gas.

Eva Ursula Muller from a UN food agency in Italy says two billion people world-wide are already supplementing their diets in this way.

(Muller) "That means one-third of the population of the world, is already eating insects."

In some parts of Africa that might mean a soft tortilla wrap packed with wriggling beetle larvae. Plenty of alternatives if you prefer your food to sit still while you eat it... many of them described as deliciously crispy.

The UN agency says the insect world is an underutilized food source.
