You do realize that you are still eating cellulose, even with organic and raw foods, right?
If you are talking about the topic if this thread, which is cellulose, and yes wood is composed of cellulose, then yes our ancestors ate it, unless you think they never ate any whole grains or fruits which are high in cellulose:

If wood pulp was ok to eat, our ancestors would have been harvesting it for our daily consumption.
Dietary fiber is a carbohydrate (or a polysaccharide) that is incompletely absorbed in humans and in some animals. Like all carbohydrates, when it is metabolized it can produce four Calories (kilocalories) of energy per gram. However, in most circumstances it accounts for less than that because of its limited absorption and digestibility. Dietary fiber consists mainly of cellulose, a large carbohydrate polymer that is indigestible because humans do not have the required enzymes to disassemble it. There are two subcategories: soluble and insoluble fiber. Whole grains, fruits (especially plums, prunes, and figs), and vegetables are good sources of dietary fiber. There are many health benefits of a high-fiber diet.
Actually, gas is one of the known symptoms of fiber consumption, and yes there are variations from person to person on how much gas any particular fiber causes:

I have seen previous poster say, "so what, it's harmless..." But these gums are not accepted by my physiology. They give me the most HORRID gas, which is very aggressive, active, and goes on for hours.
All fibers, no matter their source, can cause flatulence; however, since bacteria vary in their ability to digest different types of fiber, different sources of fiber may produce different amounts of gas. To complicate the situation, the ability of bacteria to digest one type of fiber can vary from individual to individual. This makes the selection of the best type of fiber for each individual (i.e., a fiber that improves the quality of the stool without causing flatulence) more difficult. The choice becomes a matter of trial and error.

Not surprising at all, is it? We're getting closer to the "Soylent Green" concept.
You need indigestible substance in your diet. The reason is that if it's digestible, your body turns it into more or less a liquid which if not accompanied by indigestible fiber, poses several problems. The sugars may be extracted too quickly, and you may end up becoming diabetic.

There are different types of cellulose. Wood pulp is not digestible, so that tells me that it should not be eaten.
I couldn't find anyone who recommended eating marbles so I'm not sure why you'd suggest that. But the experts do indeed recommend eating indigestible fiber. Here's part of the reason why and it mentions lowering the risk of diabetes.
Dietary fiber, dietary fibre or sometimes roughage is the indigestible portion of plant foods having two main components:
* soluble (prebiotic, viscous) fiber that is readily fermented in the colon into gases and physiologically active byproducts, and
* insoluble fiber that is metabolically inert, absorbing water as it moves through the digestive system, easing defecation.[1]
It acts by changing the nature of the contents of the gastrointestinal tract, and by changing how other nutrients and chemicals are absorbed....
Current recommendations from the United States National Academy of Sciences, Institute of Medicine, suggest that adults should consume 20–35 grams of dietary fiber per day, but the average American's daily intake of dietary fiber is only 12–18 grams.
So it appears that we may not have as many cases of diabetes if people would eat more fiber as the experts recommend. And yes, it's indigestible, and it's good for you if you eat the recommended amount, certainly from whole grains and fruits. Whether the processed varieties of fiber manufacturers are adding are as healthy is another question. I suspect you're better off with more natural sources of fiber like fruits, etc.
The main action of dietary fiber is to change the nature of the contents of the gastrointestinal tract, and to change how other nutrients and chemicals are absorbed.[1][2] Soluble fiber binds to bile acids in the small intestine, making them less likely to enter the body; this in turn lowers cholesterol levels in the blood.[3] Soluble fiber also attenuates the absorption of sugar, reduces sugar response after eating, normalizes blood lipid levels and, once fermented in the colon, produces short-chain fatty acids as byproducts with wide-ranging physiological activities (discussion below). Although insoluble fiber is associated with reduced diabetes risk, the mechanism by which this occurs is unknown.

And you know that the processed meat you buy is REAL animal meat how?
Makes you think!

While we are at it, let's ban dihydrogen monoxide as well. Yes?

You may wonder...why not most restaurants....? Because of the sodium they add to their food.

So you believe everything the "experts" tell you? They told us vegetable oils were better for us, only to find out that they are not. Only animal fats are, because they are natural and not processed.
