title: [Survey on the consumption status of trans fatty acids food among the population over the age of 3 in Beijing and Guangzhou].
abstract: OBJECTIVE
  To investigate the intakes of trans fatty acids over the age of 3 in different populations, and to determine the high exposure food and population in two cities.
  
  
  METHODS
  Use food frequency survey to investigate the frequency and the average intake of food containing trans fatty acids among subjects in the past three months.
  
  
  RESULTS
  The first ranks high exposure food is vegetable oil, while other food is different in sequence among two cities. The common high exposure populations are 13-17 years old groups and students at school groups.
  
  
  CONCLUSIONS
  The high exposure food and population are different among two cities, and the reasons are so various that we need further research.
