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.
