Abstract
The excessive ingestion of saturated and trans fatty acids on a diet has been associated with an increased risk of getting cardiovascular diseases. In Brazil, the Federal Directive RDC 360/03 of the National Agency for Sanitary Surveillance (ANVISA) demands the declaration of the contents of total fat (TF) or total lipid (TL), saturated fatty acid (SFT) and trans fatty acid (TFA), among other nutrients, on the labels of packed foods as an strategy to prevent chronic diseases. One of the attributions of official laboratories is to certify the stated nutritional contents on food package labels by means of analytical investigation. However, definitions about lipidic components of foods, as well as the analytical methods to be used in their determination, have not been uniformed yet. Considering the legal requirements, the diversity of available analytical methods, and mainly to the rights of customers to obtain reliable information, the present review aims to discuss aspects of the legislation on obligatory nutritional food labeling and the critical steps of analytical methods employed to quantify the lipidic components. These methods may lead to significant divergence on the values of contents of such nutrients. Emphasis is made on evidences of the need for standardization of methodologies for this specific purpose at Brazilian laboratories. This strategy surely will contribute to guarantee the rights of customers to receive uniform and exact information on available foods, so they are able to choose those considered healthier and to facilitate the insertion of Brazilian food products into the international trade.
