One of the most persistent myths surrounding GMOs is the supposed long-term harm on our delicate internal landscapes — the “gut” (of microbiome fame) in particular.

Yet a 2025 study is poised to put some of those lingering doubts to rest. This singular study … is framed as the unceremonious end of the “emotional era,” a bookend to the remarkable proliferation of nonsensical, dubious, and boldfaced lies swirling around GMO safety in our diets.

In a nutshell, the authors found that GM(O) maize had 1) no significant effect on the gut microbiota of macaques, 2) did not harm macaques or their offspring, and 3) supported the safety of GM maize in nonhuman primates (NHP’s).

Basically — when performing a whole digestive accounting — the presence of GMO proteins (plant incorporated protectants — biodegradable, selective insecticides keyed to pest caterpillars, and glyphosate tolerance) didn’t move the metabolic needle radically askew; in fact, it hardly budged. 

So is the “science settled” on the health effects of GMOs? In the wake of this study … and an already exhaustive supporting body of literature, it’s time to let biotech flourish.
