中国总膳食研究三十年之演变

The 30 years’ evolution of China total diet study

总膳食研究是世界卫生组织极力推荐成员国评估某个国家和地区在不同人群组对于膳食中化学危害物暴露量和营养素摄入量的最经济、有效、可靠的方法。中共中央和国务院于2019年5月9日发布《关于深化改革加强食品安全工作的意见》将开展总膳食研究作为实施风险评估和标准制定专项行动的基础性工作,来完善风险评估基础数据库。本文从中国总膳食研究的意义、启动、发展与定型的历史演变过程解读这30年的发展历程,并对其在食品安全暴露科学中的作用进行述评。

Total diet study(TDS)is designed to collect concentration data of chemicals in foods analysed as consumed by the population living in a country and,if possible and where relevant,population subgroups.The WHO strongly recommends the member countries to carry out TDS and the TDS data are used to assess the chronic dietary exposure as the most economic,reliable and effective tool.China has put TDS as groundwork for the risk assessment and standard setup action plan.The comment briefly introduces the TDS background,evolution from start,development and maturity in the past 30 years.And also,it comments TDS in the position of exposure science in food safety.
