title: [Nutrition survey on the collective in Shenzhen public institution].
abstract: OBJECTIVE
  Nutrition survey on the collective who performs light physical activity.
  
  
  METHODS
  Based on weighing records and two-months energy intake, combined with the Chinese Dietary Guidelines and Chinese Dietary Recommended Nutrient Intake (RNI), 45 healthy volunteers were chosen to evaluate their current nutrient status.
  
  
  RESULTS
  The dietary structure of the collective was simple and unreasonable. Some nutrients, such as dietary fiber, vitamin A, vitamin B1, vitamin B2, calcium, magnesium, iron, zinc, copper, selenium were lower than RNI/AI, while some others (niacin, vitamin C, vitamin E, manganese, phosphorus, etc.) were higher than the standards. The proportion of three nutritious elements in diet was not appropriate. Protein and fat intakes were less than the references obviously, while carbohydrates significantly higher than the reference.
  
  
  CONCLUSIONS
  The nutrition and health status of the volunteers was not so optimistic with the lack and excess coexist for nutrients and energy.
