Avaliação do consumo e análise da rotulagem nutricional de alimentos com alto teor de ácidos graxos trans

Several studies have been carried over the last decades aiming at evaluating the effects of trans fatty acids on the organism and identifying their mechanism. However, only around one year ago it was included by law in the mandatory Brazilian nutritional food labeling. It now enables the consumer to control the consumption of trans fatty acids. The objective of this study was to evaluate the compliance of foods with high content of trans fatty acids (biscuits, ice cream, chocolate, and fast-food) with the legislation and the daily consumption recommendation by the OMS. The evaluation of Nutrition labeling indicated that some samples do not comply with the new legislation. Analysis of the questionnaires identified that 39.7% of adults and 41.4% of children consume daily at least one food with high content of trans fatty acids. The ingestion of these products exceeds the daily recommendation. Adequate fiscalization and healthy diet programs should be stimulated.

Avaliação do consumo de corantes artificiais por lactentes, pré-escolares e escolares

This study aimed at evaluating the intake of solid jelly powder, solid juice powder and soft drinks by children. The intakes were estimated through the application of a quantitative and qualitative food frequency questionnaire. The study was pursued in the pediatric nutrition ambulatory of Gaffree Guinle University Hospital in Rio de Janeiro, Brazil. Data were treated with the SPSS 8.0 software in order to analyze the frequencies and crossing of variables. It was verified that children of different ages consumed variable amounts of artificial colorings through widespread industrialized products, introduced, in many cases, before 1 year of age. The industrialized products mentioned by the surveyed population declared in their labels to contain artificial colorings such as sunset yellow (FDC 20% of the children surpassed the daily ingestion for sunset yellow. Compliance with the JECFAs recommendations and the Brazilian legislation shall only be attained by promoting educational actions that warn about the risks and stimulate the rational use of these products by consumers.This study aimed at evaluating the intake of solid jelly powder, solid juice powder and soft drinks by children.

Teores de cobre em extratos de carne in natura e processada

Chemical specification is defined as determining the concentration of different forms of physicist-chemistry individuals of an element, which together consist of the total concentration, and whereby the element in the absorbed process can be evaluated. Beef and chicken are of great importance in food, and therefore the aim of this work was to evaluate copper in different extracts obtained from applying sequential extraction of meat, thermally processed and frozen for 30 days. Copper was determined by using an atomic absorption spectroscopy. The data was dealt with statistically by using the Grubs and t Student test. Copper was found in most of the studied samples and at least two different chemical species. The predominant fractions found were represented by the ionic fraction, which weakens the metal with organic composites and promotes the dissolution of silicates and minerals. It was observed that the thermal and freezing process diminishes the total contents and influences the chemical species of the metal. Studies to identify these chemicals of copper can be be favourable when evaluating the biodisponability.
