title: [Household food availability in Brazil: distribution and trends (1974-2003)].
abstract: OBJECTIVE
  Data from household food budget surveys were examined in order to describe the regional and socio-economic distribution of household food availability in Brazil in 2002-2003 and trends from 1974 to 2003.
  
  
  METHODS
  The study uses data from the "Pesquisa de Orçamento Familiar 2002-2003" budget survey conducted by the Brazilian Institute for Geography and Statistics (Instituto Brasileiro de Geografia e Estatística) from July 2002 to June 2003, including a national sample of 48,470 households. In each household, during seven consecutive days, all monetary and non-monetary expenses with food and beverages for family consumption were registered. Crude weights of purchased foods were transformed into calories and nutrients with the use of food composition tables.
  
  
  RESULTS
  Adequate protein content and a high proportion of animal protein were found in all regions and income strata. These were the most important positive aspects identified in the household food availability in Brazil. On the other hand, all regions and socio-economic strata showed excess calories from sugar and little availability of fruits and vegetables. An excessive proportion of calories came from total and saturated fat in the more economically developed regions and in the urban milieu, as well as among higher-income families. Time-trends in metropolitan areas indicated a decline in the consumption of basic, traditional foods, such as rice and beans; notable increases (up to 400%) in the consumption of processed food items, such as cookies and soft drinks; maintenance of the excessive consumption of sugar; and a continuous increase in total fat and saturated fat content in the diet.
  
  
  CONCLUSIONS
  Patterns and trends regarding household food availability in Brazil are consistent with the increasing participation of chronic non-communicable diseases in morbidity and mortality and with the continuous increase in the prevalence of obesity.
