The organic food market's recent rapid global growth reflects the public's interest in buying certified organic foods, including packaged products. Our analysis shows that packaged foods containing fewer ingredients associated with negative public health outcomes are more likely to be labeled organic. Previous studies comparing organic and conventional foods focused primarily on nutrient composition. We expanded this research by additionally examining ingredient characteristics, including processing and functional use. Our dataset included nutrition and ingredient data for 8240 organic and 72,205 conventional food products sold in the U.S. from 2019 to 2020. Compared to conventional foods, organic foods in this dataset had lower total sugar, added sugar, saturated fat and sodium content. Using a mixed effects logistic regression, we found that likelihood of classification as organic increased as sodium content, added sugar content and the number of ultra-processed ingredients and cosmetic additives on the product label decreased. Products containing no trans-fat ingredients were more likely to be labeled organic. A product was more likely to be classified "organic" the more potassium it contained. These features of organic foods sold in the U.S. are significant because lower dietary ingestion of ultra-processed foods, added sugar, sodium and trans-fats is associated with improved public health outcomes.
有机食品市场近年来在全球范围内的快速增长反映了公众对购买经过认证的有机食品(包括包装食品)的兴趣。我们的分析表明,与负面公共健康结果相关的成分较少的包装食品更有可能被贴上有机标签。以前比较有机食品和传统食品的研究主要集中在营养成分上。我们通过额外检查成分特性(包括加工和功能用途)扩展了这项研究。我们的数据集包括 2019 年至 2020 年在美国销售的 8240 种有机食品和 72205 种传统食品的营养和成分数据。与传统食品相比,该数据集中的有机食品总糖、添加糖、饱和脂肪和钠含量较低。使用混合效应逻辑回归,我们发现随着产品标签上的钠含量、添加糖含量和超加工成分以及化妆品添加剂数量的减少,被归类为有机的可能性增加。不含反式脂肪成分的产品更有可能被贴上有机标签。产品中钾含量越高,被归类为“有机”的可能性就越大。这些在美国销售的有机食品的特点很重要,因为减少超加工食品、添加糖、钠和反式脂肪的饮食摄入与改善公共健康结果有关。
