Discrimination of conventional and organic white cabbage from a long-term field trial study using untargeted LC-MS-based metabolomics Organic Eprints
Mie, Axel; Laursen, Kristian Holst; Aberg, K. Magnus; Forshed, Jenny; Lindahl, Anna; Thorup-Kristensen, Kristian; Olsson, Marie; Knuthsen, Pia; Larsen, Erik Huusfeldt; Husted, Søren.
The influence of organic and conventional farming practices on the content of single nutrients in plants is disputed in the scientific literature. Here, large-scale untargeted LC-MS-based metabolomics was used to compare the composition of white cabbage from organic and conventional agriculture, measuring 1,600 compounds. Cabbage was sampled in 2 years from one conventional and two organic farming systems in a rigidly controlled long-term field trial in Denmark. Using Orthogonal Projection to Latent Structures-Discriminant Analysis (OPLS-DA), we found that the production system leaves a significant (p = 0.013) imprint in the white cabbage metabolome that is retained between production years. We externally validated this finding by predicting the production...

ORGANIC FOOD – food quality and potential health effects. A review of current knowledge, and a discussion of uncertainties Organic Eprints
Mie, Axel; Wivstad, Maria.
In this report, we try to approach the question “Is organic food healthier than conventional food?” from a scientific perspective. We can conclude that science does not provide a clear answer to this question. A small number of animal studies and epidemiological studies on health effects from the consumption of organic vs. conventional feed/food have been performed. These studies indicate that the production system of the food has some influence on the immune system of the consuming animal or human. However, such effects are not easily interpreted as positive or negative for health. The chemical composition of plants is affected by the production system; however, the relevance for human health is unclear, and when one focuses on single compounds such as...
