I’m trying to resolve an argument.

EDIT: Yes, you can. But you can’t digest it. The only edible parts of a tree are some specific types of tree bark. Thanks, everyone!

    Wood is mostly cellulose and lignin, which holds no nutritional value to us humans. Another comment said that termites have certain enzymes which digest it, but it’s actually the bacteria in their guts which break down the woody fibres so they can turn it into glucose. So, theoretically, maybe we could isolate those bacteria and somehow incorporate them into our guts too? I mean it probably wouldn’t work, but you never know until you try right?

    I should think you can, depending on the wood, many can be toxic.

    The bark of a Willow tree is used to make Aspirin, we smoke paper and eat many plants with less woody stems. There are certain other barks and cambium (the soft layer between the bark and the wood) that contain nutrients, such as birch, pine, elm and a few others that have been eaten by our ancestors for centuries and even have medicinal properties. We also grate cinnamon and a few others as spice. Dog food is often bulked up with ash.

    The real issue is that the hard cellulose in the actual wood part is not particularly digestible and basically pure fibre and devoid of any real nutrient value. So it would need to be boiled or blended first I imagine, or steeped as a tea. It would be revolting or taste like nothing and probably give you constipation but I doubt you would die.

    As a raw bite of a chunk of wood, no. It would be considered inedible.

    I just got started testing Google Bard, so I fed this question to it and got this reply:

    No, humans cannot eat wood. Wood is made of cellulose, which is a type of fiber that is not digestible by humans. If you eat wood, it will pass through your digestive system without being absorbed. In some cases, eating wood can cause blockages in the digestive tract, which can be dangerous.

    There are some animals that can eat wood, such as termites and beavers. These animals have special enzymes that help them to digest cellulose. Humans do not have these enzymes, so we cannot eat wood without getting sick.
