title: [Pre-packaged foods' nutritional ingredients analysis among 706 adult residents in cities in China].
abstract: OBJECTIVE
  To analyze the nutritional ingredients of daily consumed pre-packaged foods in Chinese adult residents.
  
  
  METHODS
  From October to December 2013, the nutrition labels of pre-packaged foods consumed in continuous 7 days by 706 adult residents were collected by multi-stage stratified cluster random sampling in 18 communities with 360 households in 9 cities in China including Beijing, Shanghai, Chongqing, Shenyang, Haerbin,Jinan,Zhengzhou, Changsha and Nanning. The contents of energy, protein, fat, carbohydrate, sodium and the percentages of low-fat and low-sodium foods were compared among 7 different kinds of foods including baked foods, convenient foods, leisure foods, puffed foods, milk, beverages and seasonings.
  
  
  RESULTS
  871 kinds of pre-packaged foods were collected. The median (min, max) of energy contents of puffed foods, baked foods and leisure foods were 2 155(1 638-2 785) kJ/100 g, 1 980 (582-2 639) kJ/100 g, 1 575 (353-3 015) kJ/100 g respectively. The median (min, max) of fat contents of puffed foods, baked foods and leisure foods were 30.0 (5.0-40.9) g/100 g, 20.5 (0.3-40.5) g/100 g, 15.1 (0-71.4) g/100 g respectively. The contents of carbohydrate of baked foods, convenient foods and puffed foods were high relatively, the medians (min, max) of which were 58.1(19.8-82.5), 56.5(0-90.7), and 56.1(42.6-75.8)g/100 g respectively. The sodium content of seasoning was the highest, which was 2 177 (20-12 000) mg/100 g. The protein content of beverage was the lowest, which was 0.4(0-17.8)g/100 ml.
  
  
  CONCLUSIONS
  The energy and fat contents of puffed foods, baked foods and leisure foods were high. The carbohydrate contents of baked foods, convenient foods and puffed foods were high relatively. The sodium content of seasonings was high. The protein contents of beverages were low.
