title: [Selenium concentration in food consumed in Brazil].
abstract: OBJECTIVE
  To determine the selenium content of foods consumed in Brazil.
  
  
  METHODS
  The project was carried out between 1993 and 1999. The food samples were collected in stores in several Brazilian states. The levels of selenium were determined by hydride generation atomic absorption spectrophotometry and by wet oxidation.
  
  
  RESULTS
  The highest levels of selenium were found in animal products, especially fish, and in wheat products. We found that plant products generally had selenium levels of less than 5.0 micrograms/100 g.
  
  
  CONCLUSIONS
  In Brazil a diet rich in animal products, especially fish, is important in ensuring consumption of the recommended levels of selenium.
