Although they would offer a respectable amount of fiber, wood, and bark are generally unsuitable for human consumption because they are not digested.

Wood is not a food source for humans and cannot be digested by our digestive systems, so it is not something we can consume. Consuming wood can physically affect the digestive system and result in major health issues.

Physical Damage

One of the greatest dangers of eating wood is the physical harm it does to the digestive system. Sharp edges of splinters and rough wood fibers can cause abrasions or cuts in the throat, mouth, or digestive tract, causing bleeding, pain, and infections. In addition, the indigestible fibers of wood can become stuck in the throat or mouth, which can cause discomfort and even lead to obstruction or choking of the airway. If the wood gets swallowed, it could further harm the digestive system, possibly leading to perforation or other serious complications.

For instance, people who consume a lot of wood can develop a condition referred to as “wooden tongue,” in which the indigestible fibers of the wood are lodged in the throat and mouth, which causes pain and discomfort. The condition may make it hard to consume food, speak, or swallow. It could cause serious problems if not treated.

Additionally, eating wood can also cause psychological and social problems. People who consume wood could be viewed as a scourge by their peers and experience embarrassment or humiliation due to their actions. Additionally, eating wood could indicate a psychological issue such as PICA or obsessive-compulsive disorder.

Wood-Eating Animals

Wood-Eating Animals

While it might seem strange to see animals consume wood, many species have evolved to eat this fibrous and tough substance as part of their diet.


Termites are probably the most well-known animal that eats wood, with over 2700 species found worldwide. They reside in large colonies and eat mostly wood and other substances that are rich in cellulose. To break down the tough cellulose fibers found in wood, termites depend on a symbiotic connection with microbes in their intestines, breaking down complex carbohydrates into simpler sugars.

Beavers have sharp, chisel-like teeth, which they use to gnaw through the wood and bark, and they also have special digestive enzymes that break down cellulose fibers.

Alongside their contribution to shaping the landscape and establishing wetland habitats, beavers are also a significant food source for predators of all kinds, such as bears, wolves, and eagles.


Koalas are herbivores indigenous to Australia and are predominantly fans of the eucalyptus tree. Eucalyptus leaves can be tough and fibrous and are a source of harmful substances for humans and other animals. Koalas, however, have developed unique ways to cleanse the compounds they contain and extract nutrition from leaves.

Koalas have a unique digestive system that can break down the fibrous fibers of the leaves. They also have a unique microbial community inside to eliminate harmful substances.

Although koalas aren’t exclusively wood-eaters, their dependence on eucalyptus leaves illustrates certain animals’ unique adaptations to eat fibrous and tough plant material.
