New research shows that when we eat we’re consuming more than just vitamins and protein. Our bodies are absorbing information, or microRNA.
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.
