[Survey on the consumption status of trans fatty acids food among the population over the age of 3 in Beijing and Guangzhou].

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. CONCLUSION: The high exposure food and population are different among two cities, and the reasons are so various that we need further research.
