Sawdust used in place of flour to make bread?

Go to any supermarket and check out the ingredients of “high fiber” bread. I bet you will find cellulose, aka sawdust. It doesn’t change the flavor or texture of the bread very much. Well, if you add a whole lot I suppose it would, but there are some fairly hefty additions of “cellulose” on the market today, and while the bread isn’t great, it tastes fine.

One of our dogs had a bout of colitis and was on a high fiber prescription diet for a few weeks. The fiber source was ground peanut hulls. The dog loved the taste!
