OBJECTIVE: To determine whether the current scientific literature demonstrates that a diet rich in organic FV is healthier than 1 based on conventional produce.
METHODS: A systematic search was conducted using the PubMed and Web of Science databases for articles published between January 2003 and December 2022. Articles were analyzed uniformly by 2 reviewer, using a specific template summary sheet, and scored from 1 to 5. The level of evidence and the quality of studies in humans were assessed using the Jadad score and the French National Authority for Health method.
RESULTS: A total of 12 human studies were included. Studies often reported contradictory or even opposite results, with methodological limitations. Only 6 of the 12 studies found significant associations between OF and the health outcomes evaluated.
CONCLUSIONS: The current data do not enable a firm conclusion about a greater health benefit for a diet rich in FV based on products grown organically compared with conventional farming. There is a paucity of available data and considerable heterogeneity in study designs (participants, exposures, durations, health outcomes, and residual confounding factors). Well-designed interventional studies are required.
目的:确定当前的科学文献是否表明富含有机FV的饮食比常规产品的饮食更健康。
方法:使用PubMed和WebofScience数据库对2003年1月至2022年12月之间发表的文章进行了系统搜索。文章由2名审稿人统一分析,使用特定的模板汇总表,得分从1到5。使用Jadad评分和法国国家卫生管理局方法评估了人类的证据水平和研究质量。
结果:共纳入12项人体研究。研究经常报告矛盾甚至相反的结果,有方法论上的局限性。12项研究中只有6项发现OF与评估的健康结果之间存在显着关联。
结论:目前的数据无法得出关于与传统农业相比,有机种植的产品富含FV的饮食具有更大的健康益处的确切结论。研究设计中缺乏可用数据和相当大的异质性(参与者,暴露,持续时间,健康结果,和残余混杂因素)。需要精心设计的介入研究。
