Fibers that can be digested by bacteria in the GI tract are called ________.

Question

Quizplus · Accepted Answer

Fermentable fibers can be digested by bacteria in the GI tract through fermentation, producing short-chain fatty acids such as acetate, propionate, and butyrate, which provide energy for colon cells and have other health benefits. Starchy fibers, although also digestible, are not specifically targeted for fermentation and are more commonly associated with starch-containing foods. Viscous fibers are known for their ability to form gels and slow down digestion, but not all of them are necessarily fermentable. Insoluble fibers are not digested by bacteria, and functional fibers are a broader category of fibers with additional health benefits beyond their basic nutrient properties.
