- Study Claims Link between Milk Nutrients and Farming Types
A new UK study claims that lower input non-organic and organically produced milk has been found to contain significantly higher levels of beneficial fatty acids, vitamins and antioxidants compared to higher chemical use sources. The report, which looked at variable input, organically certified and non-organic sustainable farming practices in the contrasting regions of South Wales and the North-East of England, established a link between nutrient presence and farming types.
According to the study, higher levels of ‘desirable’ fatty acids like CLA9, omega-3 and linolenic acid and the antioxidants, vitamin E and carotenoids were found in low input non-organic and Organic milk. Lower input farming, relates to the reduced use, and possible complete elimination, of chemical-based fertilizers, insecticides, and herbicides in the food supply. Compared to the higher input system, organic and non-organic milks showed a 60 per cent and 99 per cent increase respectively in the presence of conjugated linoleic acids to high input yields in the testing. The presence of carotenoids in the same samples were also found to be 33 per cent and 50 per cent higher respectively. Similarly, lower levels of more fatty acids like omega-6 and CLA10, which are linked to detrimental health impacts were found in organic milk.
