Did you know you can eat an entire tree? it will take some time but you can
When I asked a professional about this they said
"It would take a very long time to eat a tree. Trees are made up of wood, which is not a food source for humans or most animals. Even if you were able to somehow break down the wood in a tree and digest it, it would not provide the nutrients your body needs to survive. It's much better to find other food sources that are specifically designed for human consumption."
