Changes in food consumption patterns have been occurring in Brazil in recent years, caused by several socio-economic transformations in the structure of the society, which caused significant impacts in nutrients intake and, consequently, in people s health condition. Due to these changes,, which accelerated mainly after the implantation of Plano Real in 1994, it is essential to know the pattern of nutrient intake of Brazilian families, and their evolution over time, starting from the analysis of nutrients consumption sensibility to price and expenditure variations and also to consider the influence of other socioeconomic variables. The main objective in this study was to analyze the pattern of nutrient intake of Brazilian families in the period 1995-2003, based on data from Household Budget Surveys conducted in 1995/1996 and 2002/2003, for the main metropolitan regions of the country. The theoretical framework was based on the theory of consumer demand, and on the alternative approach to the consumer problem, considering that utility is derived from properties or intrinsic characteristics of goods. The functional form used to specify the demand functions was the Almost Ideal Demand System (AIDS). Results show that all socioeconomic variables considered in this study affected significantly the consumption of at least one nutrient. The analysis of consumption sensibility to prices showed that prices influence negatively the consumption of all the nutrients, so much in 1995 as in 2003. Besides, nutrients price variations , in the two years, don't cause large effects on demand. The conclusion for the year 2003 is that families tend to demand relatively more fat, cholesterol and carbohydrates than vitamins and minerals. Thus, it can be deduced that price reduction policies to improve the nutritional quality could not achieve the desired result. It was verified that, as expected, substitutability relations between nutrients, in the two years, are lower than complementarity ones. Regarding expenditures for nutrients intakes, it was verified that for 1995, expenditures influence consumption of all nutrients positively. In 2003 variations in expenditures don't have impacts on consumption of iron, phosphorus and vitamin C. Overall, results show that increases in expenditures lead to increases in nutrient intake, however, the impact on nutritional intake due the variations in expenditure will be less than proportional. On the other hand, one can say that income policies, which allow increases in spending, may be more effective in influencing consumption patterns than nutritional pricing policies. One important conclusion is that consumers will not necessarily consume more nutritious products when food patterns change, which may result in the deterioration of nutrients intake.
