Can Humans Digest RNA?

Published in Human Biology 1 min read

Yes, humans can digest RNA.

The human digestive system is equipped to break down RNA molecules, regardless of whether they are naturally occurring or modified. This process is primarily facilitated by enzymes called ribonucleases (RNases) and the acidic environment of the stomach.

How RNA Digestion Works:

  • RNases: These enzymes are specifically designed to degrade RNA. They are present throughout the digestive tract.
  • Acids: The stomach's highly acidic environment contributes to the breakdown of RNA molecules.

Essentially, the combination of RNases and acids ensures that RNA is broken down into smaller components, which can then be absorbed by the body. The USEPA (United States Environmental Protection Agency) has also acknowledged that RNA structures are likely degraded by the digestive process due to RNases and acids in the human digestive system.

Therefore, RNA consumed through food or other sources is efficiently digested by humans.
