"Our children need calcium and the coca leaf has more calcium than milk," said Mr Choquehuanca.
In past interviews, Mr Choquehuanca confessed to have stopped reading books since he discovered his Aymara heritage and claims 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," said Mr Choquehuanca.
He said his information on the nutritional value of the coca leaf came from studies done by the Bolivian Health Ministry and Harvard University, in the United States.
Coca leaf is chewed by millions of Bolivians as a tonic and to stave off hunger and is also processed into cocaine and sold abroad, chiefly in the United States, in a multi-billion dollar illegal trade.
