Fiber is a heterogeneous category with diverse substrates and cannot be broadly categorized.

“So, uh, as you're alluding to, fiber is very heterogeneous, very different. And we even break it down further than that. You're probably thinking of, you know, soluble versus insoluble, uh, or resistant starch versus starch. But I look at fiber as like just a giant community of different substrates if you will. So we have long chain, short chains, hydrophobic, hydrophilic, positive, negative. It's like saying all animals are the same. Humans are the same as cockroaches, the same as cats. You can't lump that broadly.”
