Question: How does the colon digest fiber?

Answer:

Soluble fiber is still undigested when it reaches the colon. It is attacked by bacteria that ferment the polysaccharides to produce gases (carbon dioxide, hydrogen, methane, and volatile fatty acids). Unfortunately, gas production is a byproduct of a  higher fiber diet. The good news is it can be minimized if fiber intake is increased gradually, allowing intestinal microflora to adapt.
