Would eating undigestable polysacharrides = insoluble fiber?

There are 2 types of fiber which we can eat: Soluble and insoluble. We should consume about 25 g of fiber every day, and it doesn't matter which we eat.

Insoluble fiber is not digested, and it simply has bulk and lowers the density of the food in our gut. It makes the bolus more mobile, I believe, and probably it makes water more easily extractable. However, keep in mind, the insoluble fiber leaves the body in pretty much the same form as the way it came in.

So, I was thinking, would eating something like chitin or cellulose or shrimp exoskeleton - all 3 are made of sacharrides, indigestible, and harmless - have the exact same positive effect on our GI system as eating insoluble fiber?

No. The effect will not be the same. Cellulose will be non-effective, in the sence that it will increase the bulk but will not increase calories.Chitin and shrimp exoskeleton will have different effect. They contain Notrogenous groups, such as NH2, which may have adverse effects. This may very from person to person.
