Short YouTube segment by Dr. Ron Najafi (uploaded May 14, 2024) arguing that both insoluble (cellulose) and soluble (globular) fiber are needed because they work together to form a "secondary impenetrable barrier" that lines the intestine. The speaker uses a fishnet analogy: insoluble fiber is the fishnet and soluble fiber plugs the holes, producing a combined protective barrier.
