UN says: why not eat more insects?

A U.N. food agency is pushing a new kind of diet for a hungry world.

It ranks high in nutritional value and gets good grades for protecting the environment: edible insects.
 
The Rome-based Food and Agriculture Organization on Monday hailed the likes of grasshoppers, ants and other members of the insect world as an underutilized food for people, livestock and pets. 
 
A new report says 2 billion people worldwide already supplement their diets with insects. Insects are high in protein and minerals, need far less feed per kilo of mass than cattle do and produce far less greenhouse gas per kilo than pigs. 
 
While most edible insects are gathered in forests, the U.N. says mechanization can ratchet up insect-farming production.
 
Now, most insect farming serves niche markets.
