GM foods are a hot topic right now, with debates occurring across the country about what exactly are the effects of genetically modified foods in the human diet. The agricultural-industrial complex is pro- genetically modified foods, and disputes arguments that raise concerns about their safety. Meanwhile, do a Google Search for genetically modified foods and you’ll discover a huge community that are anti-GMO. Whether they are against environmental impacts, or just worried about the possible health effects, people around the world are concerned about the sudden ubiquity of genetically modified foods.

And now, it seems, with good reason. A recent study has shown that pigs were harmed by the consumption of feed containing genetically modified crops. The study, conducted by Dr. Judy Carman of Australia’s Flinders University, studied two groups of female pigs. The first group was fed a typical diet containing GM soy and corn. The second control group was fed an equivalent diet of non-GM foods. The pigs were otherwise reared under identical housing and feeding conditions. At the end of the study, the female pigs in the GM-fed group had markedly higher levels of stomach inflammation than the pigs in the control group. Additionally, the GM-fed females had on average a 25% heavier uterus than non-GM-fed females, which is a possible indicator of disease and definitely requires further investigation.

Dr. Carman explains that the study is noteworthy for several reasons: First, the results were found in real on-farm conditions with the added benefit of strict scientific controls – the scenario the researchers studied occurs regularly around the world, making this globally relevant. Second, the study focused on pigs, which are a major contributor to the human food supply. What goes in pigs winds up in the human diet. And third, pigs have a remarkable genetic similarity to humans, especially in their digestive systems, so people could easily suffer the same problems as the test animals.

If nothing else, this study shows that further study is needed before we all widely except GM foods into our diet. Consider buying from non-GMO companies like Whole Foods or Trader Joe’s. You can read more about the study at GMO Judy Carman.
