Teaser, yes, and what is the source of the cellulose? By what process is the cellulose obtained? What chemicals?

I agree about the pellet feed. This is a confounding variable in their deciding a mouse diet will determine something about people.

I often call supplement companies to ask the source of the cellulose in the supplements. Tapioca and palm fiber in the better ones. But, no one can tell me how it is obtained.

I think using mice to decide what will happen in humans is not the best idea.
