Finally, a school lunch I could get behind...

Why is the foreign minister talking about school lunches?

Coca leaf has more nutritional value than milk and should replace it in school lunches, Bolivia's new Foreign Minister has suggested.

"Our children need calcium, and the coca leaf has more calcium than milk," David Choquehuanca said.

In past interviews, Mr Choquehuanca said he stopped reading books when he discovered his Aymara heritage, and claimed to get his knowledge from reading the wrinkles of his ancestors.

"Our children need phosphorous, and the coca leaf has more phosphorous than fish," he said. "Perhaps instead of milk in school lunches, we should be giving coca leaf to our children."
