The Very Real Danger of Genetically Modified Foods

Chinese researchers have found small pieces of ribonucleic acid (RNA) in the blood and organs of humans who eat rice. The Nanjing University-based team showed that this genetic material will bind to proteins in human liver cells and influence the uptake of cholesterol from the blood.

The type of RNA in question is called microRNA, due to its small size. MicroRNAs have been studied extensively since their discovery ten years ago, and have been linked to human diseases including cancer, Alzheimer's, and diabetes. The Chinese research provides the first example of ingested plant microRNA surviving digestion and influencing human cell function.

Should the research survive scientific scrutiny, it could prove a game changer in many fields. It would mean that we're eating not just vitamins, protein, and fuel, but information as well.

That knowledge could deepen our understanding of cross-species communication, co-evolution, and predator-prey relationships. It could illuminate new mechanisms for some metabolic disorders and perhaps explain how some herbal medicines function. And it reveals a pathway by which genetically modified (GM) foods might influence human health.
