BACKGROUND The health benefits of organic foods are unclear. PURPOSE To review evidence comparing the health effects of organic and conventional foods. DATA SOURCES MEDLINE (January 1966 to May 2011), EMBASE, CAB Direct, Agricola, TOXNET, Cochrane Library (January 1966 to May 2009), and bibliographies of retrieved articles. STUDY SELECTION English-language reports of comparisons of organically and conventionally grown food or of populations consuming these foods. DATA EXTRACTION 2… 
Effects of organic food consumption on human health; the jury is still out!
It is currently not possible to quantify to what extent organic food consumption may affect human health, because there is virtually no published data from long-term cohort studies focusing on chronic diseases and controlled human dietary intervention studies comparing effects of organic and conventional diets.
A Systematic Review of Organic Versus Conventional Food Consumption: Is There a Measurable Benefit on Human Health?
The current evidence base does not allow a definitive statement on the health benefits of organic dietary intake, however, a growing number of important findings are being reported from observational research linking demonstrable health benefits with organic food consumption.
Human health implications of organic food and organic agriculture: a comprehensive review
Overall, this review emphasises several documented and likely human health benefits associated with organic food production, and application of such production methods is likely to be beneficial within conventional agriculture, e.g., in integrated pest management.
Safety, Health and Environment
There is ‘‘little evidence of healthier benefits from organic food over those grown conventionally’’, and the only benefit that could be found in consumption of organic food was that it reduces the risk of exposure to pesticides.
Organic Food in the Diet: Exposure and Health Implications.
This review provides an update on market data and consumer preferences for organic food and summarizes the scientific evidence for compositional differences and health benefits of organic compared with conventionally produced food.

There is a need for further, especially, large cohort studies concerning the effect of organic food consumption on specific diseases development, and positive effect on selected health problems probably results from a reduced amount of pesticide residues and an increased secondary plant metabolites intake which characterize organic food.
Some Differences in Nutritional Biomarkers are Detected Between Consumers and Nonconsumers of Organic Foods: Findings from the BioNutriNet Project
The data suggest that a high consumption of organic foods, compared with very low consumption, modulates to some extent, the nutritional status of individuals with similar dietary patterns.

The authors concluded that the studies reviewed do not support the “widespread perception” that organic foods overall are nutritionally superior to conventional ones, although eating an organic diet may reduce exposures to pesticides and antibiotic-resistant bacteria.
Organic food consumption and the incidence of cancer: a systematic review protocol.
This review evaluates the association between organic food consumption and the incidence of cancer among adults and retrieves relevant studies from PubMed, CINAHL, LILACS, EMBASE, PsycINFO,, Web of Science/Web of Knowledge, and Academic Search Premiere.


Nutritional quality of organic foods: a systematic review.
There is no evidence of a difference in nutrient quality between organically and conventionally produced foodstuffs, and small differences in nutrient content detected are biologically plausible and mostly relate to differences in production methods.
A Comparison of the Nutritional Value, Sensory Qualities, and Food Safety of Organically and Conventionally Produced Foods
It is evident from this assessment that there are few well-controlled studies that are capable of making a valid comparison and there is no evidence that organic foods may be more susceptible to microbiological contamination than conventional foods.
A Comparison of Organically and Conventionally Grown Foods—Results of a Review of the Relevant Literature
This review is concerned with the summary and evaluation of the results from more than 150 investigations comparing the quality of conventionally and organically produced food or of foods produced
Human Semen Quality in Relation to Dietary Pesticide Exposure and Organic Diet
The estimated dietary intake of 40 pesticides did not entail a risk of impaired semen quality, but precautions should be taken when generalizing this negative result to populations with a higher dietary exposure level or an intake of other groups of pesticides.
Organic food: nutritious food or food for thought? A review of the evidence
Although there is little evidence that organic and conventional foods differ in respect to the concentrations of the various micronutrients, there seems to be a slight trend towards higher ascorbic acid content in organically grown leafy vegetables and potatoes.

Food security, nutritional quality and safety vary widely around the world. Reaching these three goals is one of the major challenges for the near future. Up to now, industrialized production methods
Organic Diets Significantly Lower Children’s Dietary Exposure to Organophosphorus Pesticides
It is demonstrated that an organic diet provides a dramatic and immediate protective effect against exposures to organophosphorus pesticides that are commonly used in agricultural production.

Bioavailability and nutritional effects of carotenoids from organically and conventionally produced carrots in healthy men
Results indicate that the agricultural system has neither an effect on the carotenoid content, the antioxidant capacity of carrots, nor on the bioavailability ofcarotenoids and on antioxidant, antigenotoxic and immunological effects as assessed in a human intervention study.
