RESUMO

Food consumption is influenced by countless factors, among which can be emphasized the cultural, nutritional, socioeconomic and demografic ones. One acknowledges that, as these aspects benefit the adoption of new nutritional patterns, it will also be possible to distinguish the level of fulfillment of nutritional demands of the population. Information obtained through the Family Budget Survey (POF 2002-2003), accomplished by Instituto Brasileiro de Geografia e Estatística – IBGE, concerning the population of the North and South Regions of Brazil was utilized as database in this work. An analysis of energy and nutrients disposal, at domiciliary extent, outstands among this researches’s main goals. It was also intended to assess the relative participation of groups of food and macronutrients in the Total Energetic Value – VET, as well as their variation according to the per capita monthly income and the situation of the place of residence (rural and urban). The Software Virtual Nutri was utilized for the elaboration of the analysis related to the energy and nutrients disposal. As a parameter for the assessment of vitamins, minerals and fibers disposal, it was adopted the recommendations prescribed by the Institute of Medicine (1997, 1998, 2000, 2001, 2002). Concerning the assessment of cholesterol content, the recommendation of the World Health Organization – (2003) was adopted. The statistical analysis were accomplished through the SAS (1999) Software. The multiple regression pattern was adopted in order to assess the energy and nutrients disposal, according to the per capita monthly income. Among the results, it outstands the low energy disposal for the families living in urban areas of both regions and an increase of energetic content while monthly income grows. Regarding macronutrients, it was verified a reversed relation between the participation of carbohydrates in VET and the family monthly income. The relative participation of fats presented a growth tendency proportional to an increase of income. In relation to micronutrients, the results showed a low disposal of vitamins C, B6. B12, D, E, folacin, pantotenic acid and mineral such as calcium, zinc, copper, manganese and iodin in residences for the families of North and South Regions in both geographic stratum. One emphasizes that the iron, selenium and phosphor contents approached the average forecast value only to the families of rural areas. The fiber disposal revealed to be much lower in relation to the minimum recommended value in both of the analyzed regions. The disposable content of cholesterol showed a strong association with the family incomes, with a notorious and expressive presence in residences of the South Region families. Regarding the participation of distinctive groups of food in VET, it outstands the reduced energetic contribution of fruits, vegetables and legumes for virtually all the familiary groupings. It was identified the undesirable contribution of sweets, sugars and soft drinks to the disposable VET for the families that participated in the research.
