In 2012-2013, the Organic Council of Ontario partnered with researchers at 
the Research Shop at the University of Guelph. Of all the topics out there, OCO asked the researchers to look into the topics of the health benefits of conventional versus organic dairy products and organic production practices and soil.
Conventional Versus Organic Dairy
This report finds that higher concentrations of essential fatty acids, vitamins, and antioxidants, as well as a lower risk of cancer, heart disease, and eczema are among the health benefits of organic diary consumption.
Soils & Organic Food Production
This research finds evidence that some organically grown vegetables retain more of certain nutrients after a period of storage than conventionally grown produce. Evidence suggests that these higher levels of vitamins, minerals and secondary nutrients may be a result of organic soil management through practices such as the application of organic (as opposed to synthetic) fertilizer.
