I noticed that GMO foods are not safe according to the organic food lobby. Of course, there seems to be an incredible amount of pseudoscientific claims about GMO food safety.

A paper, by Elisa Pellegrino et al. published in Nature Scientific Reports, a highly respected peer-reviewed journal, analyzed over 6000 published papers on GMO corn over the past 20 years. The researchers performed a meta-analysis of all of that research focusing on differences in productivity, toxicological, and environmental differences between GMO and non-GMO corn.

The analysis, which used data from studies conducted worldwide, not just from the USA, showed that genetically-modified corn crops had yields 5.6 to 24.5 percent higher than non-GMO corn varieties. This contradicts the anti-GMO argument that GMO corn has not increased crop yields, but it’s not the most important point that this article makes.

For example, the study also showed that GMO corn crops had statistically significantly lower levels of mycotoxins, a toxic metabolite from fungi that infect corn crops. They showed up to a 36.5% reduction in these mycotoxins in GMO corn crops. Not only are GMO corn crops fundamentally safe, they may also be safer than “conventional” corn.
