A comprehensive assessment of factors affecting obesity in Japan and their implications for global health

该项目按时完成，从多个来源收集了有关日本食品环境的数据。关于价格和食品供应的数据来自一个涵盖超市和便利店食品销售的私人数据库，而关于食品消费的信息来自全国健康和营养调查。以多种语言获得了一套涵盖欧盟和日本粮食政策的综合文件，并已汇编成一份关于农业和粮食政策及其与粮食环境和肥胖关系的多国审查报告。该项目还完成了一项对英国肥胖趋势和食物风险的调查，结果发现，日本男性和女性也存在类似的群体效应。自1960年以来，持续的过量卡路里消耗也在这篇综述中被确认，这表明英国肥胖的增长并不是最近饮食变化的结果，而是反映了英国长期以来的饮食文化和消费模式，而这在日本并没有以类似的形式发生。这项研究得出的结论是，日本的食品环境比欧盟，尤其是英国的食品环境更安全，致肥性更低，与食品环境相关的农业和食品政策可以在代际层面上预防肥胖。

This project was completed on time, with the collection of data on the Japanese food environment from multiple sources. Data on prices and food availability was obtained from a private database covering food sales at supermarkets and convenience stores, while information on food consumption was obtained from the National Health and Nutrition Survey. A comprehensive set of documents covering food policy in the EU and Japan were obtained in multiple languages, and have been compiled into a multi-country review of agricultural and food policies and their relationship to food environments and obesity.The project also completed a review of obesity trends and food risks in the UK, which found a similar cohort effect in women as has been identified in men in Japan. Consistent excessive calorie consumption since 1960 was also identified in this review, showing that growth in obesity in the UK is not a consequence of recent dietary changes, but reflects long-held food culture and consumption patterns in the UK which have not occurred in a similar form in Japan.This study has concluded that the food environment in Japan is much safer and less obesogenic than that in the EU and especially in the UK, and that agricultural and food policies related to the food environment can work at a generational level to prevent obesity.
