Here's a quotation from that article:
President Luiz Inacio Lula da Silva has challenged critics who claim biofuel production is contributing to high food prices and demand, arguing the problem lies instead in poor agricultural and distribution models.
"It is not ethanol that is causing food prices to rise, because Brazil, which produces more biofuel, also produces more food," he has said.
That view has support among government analysts.
The food crisis "is a problem of wealth distribution, a political problem," said Giselle Ferreira de Araujo, who works for the state National Council for Scientific and Technological Development.
