It’s a bit confusing because most people can not recognize the layers of trees.
So let’s put it this way: You should eat the soft inner tree bark instead of the outer tree bark that is hard as a rock.
Although tree bark has starches, sugars, calories, and fibers that sounds super nutritious, it’s still not recommended to eat tree bark if it is not your last choice.
The wooden fiber of tree bark itself is very hard to digest for human bowels. People will die from overeating of wooden fiber.
