Organic products have received longstanding, widespread attention for their nutritional and ecological benefits, as they are said to have certain positive health attributes and contain fewer harmful compounds than conventional (or non-organic) products. We reviewed the recent literature to examine potential associations between nutrient composition, gut microbiota, and gut health effects in recent comparative studies of organic and conventional dairy products. Trends of increased ratios of omega-3 to omega-6 polyunsaturated fatty acids and unsaturated to saturated fat, increased fat-soluble vitamin content, and decreased levels of certain pernicious contaminants in organic milk were observed across the studies reviewed. Studies of the metabolism of these nutrients in both in vitro and in vivo settings, and their or their metabolites' interaction with the intestinal epithelium show that nutrients enriched in organic dairy products may support host nutrient uptake and mediate gut inflammation. Research on the effects of single food products or classes of food products on gut health is rare. The extent of these benefits is highly likely to be mediated by both the magnitude of the difference in nutrient types and quantities, and by dietary intake levels of dairy products. Intervention studies directly examining the different effects of organic and conventional dairy products on gut health in humans are needed to further elucidate this relationship.
有机产品因其营养和生态效益而受到长期、广泛的关注,因为它们据称具有某些积极的健康属性,并且与传统(或非有机)产品相比,含有较少的有害化合物。我们回顾了最近的文献,以检查有机和常规乳制品最近比较研究中营养成分、肠道微生物群和肠道健康影响之间的潜在关联。在审查的研究中,观察到有机牛奶中ω-3 到 ω-6 多不饱和脂肪酸和不饱和脂肪与饱和脂肪的比例增加、脂溶性维生素含量增加以及某些有害污染物水平降低的趋势。这些营养素在体外和体内环境中的代谢及其代谢物与肠上皮的相互作用研究表明,有机乳制品中富含的营养素可能支持宿主营养吸收并调节肠道炎症。关于单一食品或食品类对肠道健康影响的研究很少。这些益处的程度很可能受到营养类型和数量差异的程度以及乳制品的饮食摄入量水平的影响。需要进行直接研究有机和常规乳制品对人类肠道健康的不同影响的干预研究,以进一步阐明这种关系。
