[Trends of energy and nutrients intake among Chinese population in 2002-2012]

To describe the energy and dietary nutrients intake trends among Chinese population from 2002 to 2012.

Data of energy, macronutrient, and micronutrient intake were collected from 2002 Chinese Nutrition and Health Survey, 2010-2012 Chinese Nutrition and Health Surveillance, and energy and dietary nutrients intake were analyzed. The 3-consecutive days-24-hour dietary recall and food weighting method were used to collect food, edible oil and condiment intake information. The dietary nutrients intake was calculated based on the energy percentage in one family and the China Food Composition.

Compared with 2002, the average energy intake per reference man per day of Chinese people declined to 2172. 1 kcal from 2250. 5 kcal in 2010-2012. Dietary protein intake was basically flat. Dietary fat intake in 2010-2012 was 79. 9 g, with urban level higher than rural level. Compared with that in 2002, fat intake increased by 4 g, and urban residents' intake fell slightly, making urban / rural gap narrower. Theintake of micronutrient such as vitamin A, vitamin C, calcium, iron, zinc was still lower than Chinese Dietary Reference Intakes and falling continually.

In the last decade, Chinese urban / rural residents' dietary energy supply was sufficient, and the dietary nutrients intake had improved. However, there were excessive intake of fat and low intake of micronutrient was still a problem among Chinese population. There was significant difference between the urban and rural area, and the dietary quality among Chinese population especially rural residents should be improved.
