Ribonucleic acid, or RNA, is a kind of molecule which is part of the DNA genetic system. DNA contains the code for creating every part of our bodies - it tells our cells how to divide, how to create proteins, how to grow and differentiate into the different tissues of our flesh, and how to metabolize. RNA is the molecule which reads these instructions and carries them out.
It's extremely interesting, then, that we have recently learned that some plant RNA can pass directly into the human bloodstream. Micro RNA (miRNA) from rice has been shown to pass into the blood of both mice and humans. We've always known the truth of "you are what you eat," but this research opens up another interesting line of inquiry: how are these organic molecules affecting the expression of our genes? Our food may be even more important than we thought.
