A recent article published by Sustainable Food Trust on 22 December 2016 in Farming, points out significant compositional changes between non-GMO corn, and Roundup-resistant GMO corn. The study was led by Dr Michael Antoniou at King’s College London. The report states,
In-depth analysis of types of proteins (“proteomics”) and small biochemical molecules (“metabolomics”) revealed major compositional differences between NK603 and its non-GMO parent. The results obtained show not only disturbances in energy utilisation and oxidative stress (damage to cells and tissues by reactive oxygen), but worryingly large increases in certain substances, most notably polyamines.
