"We have a mistaken image of worms. Our first reaction when we see them is to kill them, step on them, or take them out of the flower pots, when the truth is that they have a huge nutritional value. They help soil, even in a flowerpot, because they oxygenate the soil. So it is important that our impressions of them change, and of course they could play an important part in the diet of all Mexicans."

STORYLINE:

Mexican researchers have developed a new kind of flour made from the humble earthworm.

Earthworms are believed to have a high nutritional value, which is why researchers at the Mexican National Polytechnic in Mexico City are looking at ways to turn them into food.

As a result they have come up with the earthworm biscuit.

The earthworms are first placed on a special tray for 15 days and are fed only vegetables and fruit.

They are then dried and ground into a powder resembling flour, which becomes one of the basic ingredients of the worm biscuit.

Researcher Iliana Mendez Barajas says the popular image of the earthworm as something to step on needs to change.

Not only do they oxygenate the soil, she says, but they could eventually become a big part of the Mexican diet.
