title: [Study on the acryl amide intake in the Beijing diet].
abstract: OBJECTIVE
  A 24-hours recall study was performed to get the acryl amide intake in the Beijing diet.
  
  
  METHODS
  24 separate items bought in the Beijing Market were analyzed and 2460 diet lists (820 participants x 3 days) were calculated.
  
  
  RESULTS
  The following mean intakes of acryl amide have been estimated (microg/dm): males 18.6, females 16.6. For the 97.5 percentile of the population the intake is estimated to: males 59.0, females 50.4. As dose calculated per kg bodyweight the mean intake becomes [microg/(kg bw x d)]: males 0.282, females 0.284. For the 97.5 percentile [microg/ (kg bw x d)]: males 0.898, females 1.007. The contribution of the different meals and to the intake was as follows: breakfast 20.48%, lunch 38.99%, dinner 39.42%, snacks 1.17%.
  
  
  CONCLUSIONS
  The survey leads to the conclusion that lunch and dinner are significant sources of acryl amide in a typical Beijing diet even if they have relatively low levels of acryl amide. Chinese traditional breakfast food is also an important source of acryl amide in a typical Beijing.
