Tag: Swallowing wood

Humans lack the necessary enzymes to break down cellulose, the main component of wood, meaning our digestive system cannot process it. Therefore, the fate of a swallowed piece of wood depends heavily on its size, shape, and how it interacts with the sensitive tissues of the digestive tract.

Approximately 30% of all plant cell walls are made of cellulose, the primary component of wood, which humans cannot digest. Given this fact, can you eat a little bit of wood without harm, or is it a dangerous idea? While a very small, smooth piece may pass without issue, ingesting wood is not recommended and carries several health risks.
