摘要:

食物消费是人类最基本的消费行为。以中原地区典型城市郑州市为例,通过问卷调查和跟踪称重方法,获取了309户城市家庭的一手食物消费数据,定量分析了现阶段我国典型城市家庭食物消费的差异。研究表明:(1)郑州城市家庭人均食物消费总量为372.32 g/餐。其中,植物性食物的消费量约为动物性食物的3倍。(2)三个样本城区中,惠济区水产品和水果的人均消费量远低于金水区和二七区;收入水平较高的家庭,蔬菜、主食的人均消费量占人均食物消费总量的比例趋于减小,而水产品、奶类和水果的比例趋于增加;人口规模较小的家庭比规模较大的家庭人均食物消费量大。(3)通过与中国居民平衡膳食宝塔推荐的食物摄入量对比发现,郑州城市家庭主食类和蔬菜类消费量合理,畜禽肉和蛋类的消费量过高,粗杂粮、水果、奶类和大豆摄入不足。实证研究为进一步准确获取居民食物消费基础数据提供了参考,并为相关政策的制定提供了科学依据。

Abstract:

Food consumption is the primary way to get access to the basically-needed energy and nutrition for human being. Our investigation was conducted in Zhengzhou city, one of the provincial cities in central China, by a 3-consecutive-day household weighting survey. We gained a first-hand dataset consisting of 309 urban households in Zhengzhou and their food consumption data. Our research reveals that: (1) Urban households in the study city held a 372.32 g of food consumption for each meal per capita, which was dominated by plant-based foods (277.12 g). The ratio between plant-based foods and animal foods was 3∶1. (2) Among the three urban districts, Huiji consumed more sea food and fruits compared with Erqi and Jinshui. The per capita consumption of staple foods and vegetables for households in the city tended to decrease as annual per capita income rose, while that of fruits, seafood and dairy increased. Households with a smaller population consumed more food per capita compared with those with a larger population. (3) Furthermore, the comparison of research results and the general dietary guidelines indicated that the dietary pattern of urban households in Zhengzhou need to be further adjusted. Briefly, their meats consumption far exceeded the recommended upper threshold, while the consumption of dairy products and fruits did not reach the recommended anount. In the following application of "Health China" and other relevant national strategies, we should continue to highlight the urban household food consumption, promote and diversify the content and form of nutrition & health education in communities and families. The excessive meat consumption needs to be reduced in a reasonable range, and the high-nutrition foods should be expanded and encouraged.
