The most dangerous fiber in the world is refined fiber. Certain fiber in its natural form feeds your microbes, helping them thrive. Refined fiber is junk food for your microbes. Fiber is often considered important, but it can cause problems for many people.

When you eat onions, berries, beans, and other natural sources of fiber, they provide the body with polyphenols. Polyphenols help determine which microbes are fed in the gut. This means polyphenols selectively support good bacteria while suppressing bad bacteria.

Refined fibers such as chicory root fiber, soluble corn fiber, and tapioca fiber are ultra-processed foods for your microbes. Similar to refined sugar and carbs, refined fiber is processed with chemicals, heat, and enzymes.

Huge amounts of processed fiber are being added to our food. This allows the wrong bacteria to take over the gut, contributing to conditions like small intestinal bacterial overgrowth (SIBO), leaky gut, inflammation, and autoimmune disease.
