RESUMO

The aim of this work was to analyze the availability of energy, nutrients and carotenoids for resident Brazilian families in the rural and urban areas according to Geographic Regions and Federal District. Individual information obtained through the Family Budget Survey (POF 2002- 2003), applied by Brazilian Institute of Geography and Statistics (IBGE) was used as database. For the energy and nutrients analyses, the software Virtual Nutri was used. As a parameter for the assessment of qualitative analysis in Total Energy Value (VET) and the evaluation of the availability of vitamins and minerals, recommendations prescribed by the Institute of Medicine (1997, 1998, 2000, 2001, 2002, 2004) were adopted. In relation to the evaluation of the carotenoids content in foods, the information contained on the table Nutrient Database for Standard Reference Release 19 - United States of Department Agriculture (USDA) was adopted. The resources of software Statistical Analysis System – SAS were used to calculate the average availability of nutrients. The results present reduced availability of energy for the Brazilian families and particularly for people who live in urban areas. Among the resident families in the rural areas, there was a higher participation of the carbohydrates in the VET, mainly for those ones located in North, Northeast, Southeast Regions and Federal District. The participation of macronutrients in the VET, for the families who live in urban residences and for the total of the Regions, were in compliance with the recommended values. The availability of vitamins A, B1 and B2, for the total of families, reached the recommendation adopted as reference in this research. In relation to vitamin C, vitamin B6, vitamin B12, folacin and pantothen acid, the Brazilian families had access to quantities which are lower than the recommendations. Regarding the minerals, the content of calcium, magnesium, zinc and potassium showed were reduced. The access to carotenoids was insufficient in the Brazilian residences. However, it is very interesting to mention that the average content of β-carotene, lutein and zeaxanthin, provitamins A and the total identified carotenoids for the families who live in rural areas was higher than that one verified in the residences located in the urban areas. On the other hand, the families who live in the urban areas dispose of higher amounts of α-carotene, β-cryptoxanthin and lycopene. In rural residences of the South Region, it is verified a higher availability of carotenoids (total) when compared to the contents observed in the residences located in others Regions of the country. The conclusion is that there are different food standards in the country which vary according to the analyzed data, considering the Geographic Regions and the sectors (urban and rural), where the families live. Due to the average availability in the residences, where some nutrients were lower than the values in reference, it is necessary an urgent search for strategies that contribute for the access to foods and the improvement of the habits and the food standards of the Brazilian population. It is very important to mention that the analyses are restricted to residence acquisition and the accomplishment of research that identifies the nutrition contribution of food away from home is essential for the establishment of the strategies.
