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.
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?
So there is a future, where us humain, go to the restaurant and open the Wood card, and a waiter specialized in wood (certainly french too) will go, Hello, Monsieur, Madame, have you chozen your wood for tonight
And our grand kids will respond: "Yes, We will take the Cypress of Bordeaux"
And this wonderful french waiter will respond "Very Good Choice with a Fish Sir, It creates a wonderfool Surf and Turf taste
That's interesting in that it's the termites' gut flora that break down the woody content they ingest, considering that a mycelial presence is required to convert grassland to forest as the bacteria present in soil are unable to process the dendritic xylem in order for reuse in the substrate. Do you know if these termite bacteria are viable alternatives to fungal synthesis in reforestation projects?
Depends on the wood. Some wood we use for spices like cinnamon so you've probably already eaten that. But other types of wood are considered toxic not only to consume, but to the plants around it. Take what I say with a grain of salt as I'm certainly no expert on the matter.
Hemlock comes to mind, as with or without your proffered grain of salt, it can be eaten but is definitely not edible. Those defs are posted in a non-pedantic way above, incidentally.
Also, thanks for the chance to use the word 'proffered' in conversation, it's vanishingly rarely used outside the legal field.
The tree makes the best bedtime tea I've ever had. The herb is a common poison notorious for killing Socrates. You're still technically accurate, but they're very different plants.
Saw dust have been mixed with flour multiple time in history during famine period. However it was mostly done to increase profit, not for its nutritional value and multiple bakers have been killed by angry mob because of that.
This guy Jesse on Alone Season 5 was running out of food and had read about native tribes creating bread from tree bark, so he stripped some off a pine tree and ate it. It seemed edible but hard to pass. The video shows the aftermath, basically he had to tap out and be rescued due to severe abdominal pain. However, apparently it is a thing, I'm not sure how you could do it in a way your stomach can handle though, and most likely it has to be specific species of trees.
You shouldn't eat anything from a pine tree. Or even cook with pine wood. You might be able to eat bark from some other type of tree, but pine is toxic.
This simply isn't true at all and I have no idea why you would even make that up. Pine is the most diverse family of conifers with over 800 different species, many of which are used in a variety of cuisine and teas. I've been chewing on white pine needles all my life as they're known to be rich in vitamins and help reduce dehydration.
Then there's the fact that almost all species of pine produce edible nuts. The species that produce the largest nuts are cultivated for commercial sale which is why you can find pine nuts in high end grocery stores and fine cuisine.
Does bamboo count? It's a common wood flooring and cutting board option. Lots of furniture is made from it. It's used like wood, even though it doesn't grow quite the same as a normal tree. And people have been eating bamboo shoots for a long time.
Oh right, I just remembered that Norway did make something like "bark bread" in the past during famines, and that linked Wikipedia article says:
The inner bark is the only part of a tree trunk that is actually edible; the remaining bark and wood is made up of cellulose, which most animals, including humans, cannot digest.
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.
I looked up cellulose and it does say that it is used in some drugs and other consumables yeah, but it's still indigestible, so it wouldn't give you any nutrients to survive if eaten by itself, I guess.
If you mean "Can be chewed and swallowed without causing undue harm", then, yeah, you can eat wood. Well, most wood, I'm sure there's some out there that are some level of toxic to humans.
If you mean, "can be consumed as a source of nutrition", then, no, you can't eat wood. Humans lack the capability to digest it.
still at least part of wood though, a part that's edible, as far as I'm aware, mercury has none of those (adding the bread, and extra ingredient, is cheating).
