Avalia��o de 'caneta paraguaia' tamb�m testa o jornal

The Folha de S. Paulo conducted an intriguing experiment to evaluate smuggled "emagrecing pens" from Paraguay, which turned out to be a double-edged sword: it not only tested the products but also the integrity of the newspaper itself. The procedure to verify the substances' efficacy raised questions about the ethical boundaries of investigative journalism. This bold move highlights the constant scrutiny newspapers face in maintaining credibility while exploring controversial topics. It’s a reminder of how investigative journalism can sometimes walk a fine line between exposure and ethical responsibility.
