Resumen
A ingestão excessiva de ácidos graxos saturados e trans na dieta tem sido correlacionada ao aumento do risco de doenças cardiovasculares. No Brasil, conforme a Resolução RDC 360/03 da Agência Nacional de Vigilância Sanitária (ANVISA) é exigida a declaração do teor de gordura total (GT) ou lipídios, ácidos graxos saturados (AGS) e trans (AGT) na rotulagem dos alimentos embalados, entre outros nutrientes, como estratégia de prevenção das doenças crônicas. Cabe aos laboratórios oficiais verificarem os teores declarados por meio da análise. No entanto, não estão uniformizadas as definições quanto aos componentes lipídicos, tão pouco quanto aos métodos analíticos a serem adotados, inclusive nos laboratórios brasileiros. Considerando-se as exigências legais, a diversidade dos métodos analíticos disponíveis e, principalmente, o direito do consumidor de obter informações confiáveis, a presente revisão teve como objetivo abordar aspectos sobre a legislação de rotulagem nutricional obrigatória dos alimentos, bem como sobre as etapas críticas dos métodos analíticos de quantificação dos componentes lipídicos. Estas etapas podem levar a divergências significativas nos teores obtidos para os nutrientes. Reforçam-se as evidências da necessidade de padronização das metodologias nos laboratórios brasileiros. Tal padronização contribuirá para garantir o direito do consumidor em obter informações uniformes e exatas sobre os alimentos que adquire, e possibilitará a escolha dos mais saudáveis, além de favorecer a inserção dos produtos brasileiros no mercado internacional.
