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

该项目按时完成，从多个来源收集了关于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则来自国家健康和营养调查。以多种语言获得了一套涵盖欧盟和日本食品政策的综合文件，并将其汇编成一份关于农业和食品政策及其与食品环境和肥胖的关系的多国回顾。该项目还完成了对英国肥胖症趋势和食品风险的审查，发现女性的队列效应与日本男性相似。这项研究还发现了自1960年以来持续的过高卡路里消耗，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持有的饮食文化和消费模式，这在日本没有出现过类似的形式。这项研究得出的结论是，日本的食品环境比欧盟，特别是英国要安全得多，肥胖发生率更低，与食品环境相关的农业和食品政策可以在一代人的水平上预防肥胖。

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.
