摘要:

我國農(nóng)業(yè)資源嚴重短缺，但食物分配不均與超重肥胖問題卻日益嚴峻，不僅困擾人口健康，而且導(dǎo)致食物與資源嚴重浪費，從食物需求管理視角研究引導(dǎo)居民合理熱量攝入對于人口健康和農(nóng)業(yè)資源節(jié)約具有重要意義?；谛枨罄碚?，拓展并構(gòu)建納入膳食知識稟賦的居民體重管理決策理論模型，利用中國健康與營養(yǎng)調(diào)查（CHNS）數(shù)據(jù)，分析收入增長與膳食知識對超重個體熱量攝入的影響，探討兩者影響超重個體熱量攝入的作用機制。結(jié)果表明，膳食知識增加能有效減少超重個體熱量攝入，主要通過減少谷物類食物攝入量，實現(xiàn)食物攝入量減少和熱量攝入量下降。收入增長對超重個體熱量攝入無顯著影響。收入增長的直接效應(yīng)提高了食物消費總量；收入增長引起的食物結(jié)構(gòu)升級減少了谷物食物和油脂攝入，增加了蔬菜水果和肉蛋奶類食物攝入；谷物類食物和油脂攝入減少引起的熱量下降很大程度上抵消了肉蛋奶食物攝入增加引起的熱量增加。這一結(jié)果對熱量攝入無收入彈性提供了一般性的解釋。因此，政府相關(guān)部門有必要對超重人群給予膳食指導(dǎo)，并采取相關(guān)干預(yù)政策增加超重居民膳食知識，調(diào)整不健康的飲食行為，增加體育鍛煉。

Abstract:

China has a huge shortage of agricultural resources, but the problem of uneven food distribution and overweight are becoming more and more serious. At the same time, it leads to the health of the population and causes serious waste of food and resources. It is of great significance to guide residents to rationally invest in population health and the conservation of agricultural resources. Based on the demand theory, this article expands and constructs a theoretical model for residents’ weight management decision, which incorporates dietary knowledge endowment. Based on the data of China Health and Nutrition Survey, this paper analyzed the impacts of income growth and dietary knowledge on the caloric intake of overweight individuals, and explore the influencing mechanism of them on calorie intake. Results show that increased dietary knowledge can effectively reduce the caloric intake of overweight individuals, mainly by reducing the intake of cereal foods to reduce food intake and caloric intake. Income growth has no significant influence on the caloric intake of overweight individuals. The direct effect of income growth has increased total food consumption, while the upgrade of food structure has reduced cereal and fat intake, and increased vegetable, fruit, meat, egg, and milk food intake. The reduction in calories from reduced cereal and fat intake largely offsets the increase in calories from increased meat, egg and milk food intake. The findings of this research provide a general explanation for the lack of income elasticity of calorie intake. Therefore, this paper suggests that the Governments should provide dietary guidance for those overweight individuals, adopt relevant intervention policies to increase their dietary knowledge, change unhealthy eating behaviors, and increase physical exercise.
