The exposure terms searched (including all headings, subheadings, and title/abstract terms of the Medical Subject Headings) were as follows: organic, health food, conventional combined with food, agricultural crop, livestock, agriculture, production, nutrition, diet, and consumption. None of the authors declared a conflict of interest. 312 lactating women in the KOALA Birth Cohort, Self-reported habitual diet defined as conventional (<50% organic), moderately organic (50–90%), and strictly organic (>90%) at 34 wk of pregnancy. 2014;51(3):746–755. Experimental in vitro human cell cultures, Extracts of 2 strawberry cultivars either organically or conventionally produced at 4 concentrations. An examination of the full text of these articles resulted in the exclusion of 37 studies that did not meet the inclusion criteria (Figure 1). Data extraction was performed in duplicate for all included articles by 2 independent reviewers (AA and AH), and any inconsistencies were corrected as necessary in consultation with the project lead (ADD). Thus, direct comparison of nutrition-related health effects of organic compared with conventional foodstuffs can be complicated by varietal differences in the exposure under investigation. As far as possible, we adhered to the guidelines for the reporting of systematic reviews (9). Establishing the strength of the existing evidence base that relates to nutrition-related health benefits of organic food consumption will assist policymakers in the development of evidence-based statements on potential public-health gains or risks that result from organic food consumption and support consumers to make informed choices. 2009;111(10):1098–1119. Mixed results for individual cultivar extracts and for lower concentrations. Subject experts (n = 23) identified from relevant publications were contacted by e-mail; we received 12 responses and were sent 11 publications that were all either not relevant (n = 1) or had previously been identified (n = 10). J Environ Manage. pre-eclampsia, hypospadias) and obesity. Design: We systematically searched PubMed, ISI Web of Science, CAB Abstracts, and Embase between 1 January 1958 and 15 September 2008 (and updated until 10 March 2010); contacted subject experts; and hand-searched bibliographies. COVID-19 is an emerging, rapidly evolving situation. Studies were defined as being of satisfactory quality if they met all 4 criteria. 2012;112:309–320. A hand search of reference lists of studies included in the review was conducted to check the completeness of the initial electronic searches. Briviba K, Stracke BA, Rüfer CE, Watzl B, Weibel FP, Bub A. Caris-Veyrat C, Amiot MJ, Tyssandier V, et al. eCollection 2013. The 2 large population studies used measures of self- or proxy-reported exposure (15, 16) and proxy reports of diet when necessary (16% of study participants) (15). A hand search of reference lists of the 63 potentially relevant articles identified one additional relevant study (11). 2019 Dec 18;12(1):7. doi: 10.3390/nu12010007. Organic and conventionally produced wines, Copyright © 2020 American Society for Nutrition. There were several reasons for the exclusion of potentially relevant articles, which included the lack of a study outcome of direct relevance to human public health (n = 22) and the absence of a direct comparison of the health effects of organic compared with conventional foodstuff consumption or exposure (n = 8) (see supplemental material under “Supplemental data” in the online issue). Evidence in this field may be improved if more interdisciplinary approaches to, and funding for, agricultural-health research were supported. Before publication, we updated our systematic review to 10 March 2010 to ensure that we included the latest research reports. Benbrook CM, Butler G, Latif MA, Leifert C, Davis DR. PLoS One. 2014 Sep 14;112(5):794-811. doi: 10.1017/S0007114514001366. Multiple-database searching [PubMed, ISI Web of Science (, CAB Abstracts (, and Embase (] was used to ensure comprehensive article retrieval in the original systematic review (to 15 September 2008), and 2 key databases (PubMed and CAB Abstracts) were searched in the systematic review update (to 10 March 2010). Despite the relatively low quality threshold used in this review, a disappointingly small number of studies were graded as being of satisfactory quality. This systematic review of the available published literature was designed to determine the strength of the evidence that nutrition-related health benefits in humans could be attributed to the consumption of organically produced foodstuffs.

Br J Nutr. Numerous health benefits have been ascribed to antioxidants, but evidence linking antioxidant concentrations in foods, serum antioxidant concentrations after dietary consumption, and specific in vivo mechanisms of action for potential human health effects is mixed. Pesticide residue content. None of the clinical trials in the review were reported according to CONSORT guidelines (, which are an evidence-based, minimum set of recommendations for reporting randomized controlled trials (25). Background: There is uncertainty over the nutrition-related benefits to health of consuming organic foods. The methods used for the measurement of exposure also varied. Akcay YD, Yildirim HK, Guvenc U, Sozmen EY. The sweeping public opinion that organic food is healthier than conventional food is quite strong and is the main reason for the increase in its demand over the past 5-6 years. The nutritional composition of monogastric animal source foods has been shown to be sensitive to feeding practices (26), and this may have an effect on health (27). Few studies investigated the health effects of livestock products.
