title: [A survey on the contents of nutrient and nutrition in the orderings of customers when eating at three restaurants in Beijing].
abstract: OBJECTIVE
  To study the median nutrient content of customers' ordering in the restaurants in Beijing.
  
  
  METHODS
  The median contents of nutrients regarding ordering/per person from the customers were estimated, via combining the nutrient content of menu offering. Data, based on all weights of ingredients and Chinese food composition with all the ordered records from customers, was collected within a set period of time, from 2011 to 2013. Nutrition status was then estimated, under the Nutrient-Rich Foods (NRF).
  
  
  RESULTS
  The median energy intake reached 4 973.9 (P25-P75: 3 575.6-6 971.0) kJ and 88.2% of the tables were exceeding the recommended energy limits, respectively, with 3 347.2 kJ for lunch and 2 510.4 kJ for dinner. Data was gathered from three restaurants in Beijing. In all the three restaurants, the median nutrient contents appeared 70% outnumbered the daily value of fat and cholesterol. The median sodium contents (87.9%) were also over the standard set for sodium adequate intake. In addition, the median nutrition on fibers, calcium, vitamin A, vitamin C and vitamin E were far below the recommended nutritional intakes (RNI), in the ordering. For NRF9.3, the Wenzhou restaurant showed the highest score (5.50) but the restaurant in Yunnan appeared the lowest (2.26), with difference statistically significant (P<0.001).
  
  
  CONCLUSIONS
  Eating-out habit ended in taking low nutrition with higher limited nutrients, but with low recommended nutrients, when compared to the recommended Chinese Dietary Reference Intake.
