effects of organic farming on human health
Differences in the composition between organic and conventional crops are limited, such as a modestly higher content of phenolic compounds in organic fruit and vegetables, and likely also a lower content of cadmium in organic cereal crops. Kratz S, Schnug E. Schwermetalle in P-Düngern (Heavy metals in P fertilisers, in German). Two notable exceptions are the pyrethrins and copper. Thus a high intake of fruit and vegetables is positively correlated with pesticide excretion , and frequent consumption of organic produce is associated with lower urinary pesticide concentration . Consumers of organic food have a comparatively low dietary exposure to pesticides. The production system does not have any observed effect on the concentration of ochratoxin A (OTA), another fungal toxin of importance in cereal production . Restricted use of antibiotics in organic farms decreases the problems of resistant bacteria attacking humans. Frick and Bonn: FiBL and IFOAM – organics international; 2017. Also, the actual differences in feeding regimens between conventionally and organically raised animals may differ by species, and by country. For certain population groups and fatty acids, these numbers could be higher, and an increased omega-3 PUFA consumption is generally desirable, as some subpopulations have a lower-than-recommended intake of omega-3 PUFA . European Food Safety Agency. 2015. Suggestive evidence indicates that organic food consumption may reduce the risk of allergic disease and of overweight and obesity, but residual confounding is likely, as consumers of organic food tend to have healthier lifestyles overall. These studies are to some extent complemented by experimental studies using animal models and in vitro models. 2014;99(1):35–45. Tscharntke T, Clough Y, Wanger TC, Jackson L, Motzke I, Perfecto I, Vandermeer J, Whitbread A. 2014;110(9):2321–6. Antibiotikaresistens og -forbrug i slagtesvineproduktionen (antibiotic resistance and use in pig production, in Danish). 2008;7:50. The European Parliament has brought out a report titled “Human health implications of organic food and organic agriculture”, which details the impact of organic food and organic farming on our health. San Diego: Academic Press; 2012. p. 271–82. 2015;136(4):719–29. None (0%) of the organic samples exceeded the ARfD . The organic production system is believed to influence the nutritional quality of foods. Although it is rare for conventional farms to adopt knowledge about management and housing from organic production except when converting farms in line with organic standards, there may be options to improve animal health and welfare by knowledge transfer to conventional farms in order to reduce the use of antibiotics . Fourth National Report on human exposure to environmental chemicals, opdated tables september 2013. Accessed 19 Sept 2017. United States Environmental Protection Agency (EPA): Literature Review on Neurodevelopment Effects & FQPA Safety Factor Determination for the Organophosphate Pesticides. Metabolomics [148,149,150,151,152], proteomics [153, 154] and transcriptomics [155, 156] studies in controlled field trials provide evidence that the production system has an overall influence on crop development, although there is no direct relevance of these studies for human health. : (+ 34) 608 95 06 41 Data from paper by Średnicka-Tober et al. Front Nutr. That being said, the published data do suggest that: 1. Benefits of Organic Farming. 2012;92(14):2923–7. Application of the general principle of organic regulations about transparency throughout the food chain can be used to mitigate emerging problems of transmission of antimicrobial resistance. Tel. Alfven T, Braun-Fahrlander C, Brunekreef B, von Mutius E, Riedler J, Scheynius A, van Hage M, Wickman M, Benz MR, Budde J, et al. Thus, organic food production has several documented and potential benefits for human health, and wider application of these production methods also in conventional agriculture, e.g., in integrated pest management, would therefore most likely benefit human health. supporting a development towards a sustainable use of pesticides . Epidemiological studies have reported adverse effects of certain pesticides on children’s cognitive development at current levels of exposure, but these data have so far not been applied in the formal risk assessments of individual pesticides. Associations of dietary patterns with the risk of all-cause, CVD and stroke mortality: a meta-analysis of prospective cohort studies. 2010. All rights reserved. Wheeler T, von Braun J. Excessive nitrates from chemical fertilizers and animal waste wash into waterways, threatening public health and causing Blue Baby Syndrome. By regulation, herbivores in organic production receive at least 60% of their feed intake as roughage on a dry matter basis. In another New York inner-city birth cohort, the concentration of the organophosphate chlorpyrifos in umbilical cord blood was associated with delayed psychomotor and mental development in children in the first 7 years of life , poorer working memory and full-scale IQ at 7 years of age , structural changes, including decreased cortical thickness, in the brain of the children at school age , and mild to moderate tremor in the arms at 11 years of age .
