Emerging research is finding that soluble fibers are especially useful for maintaining gut health. While humans do not have the enzyme to break down fiber, the bacteria in the intestine are able to metabolize it. This fiber acts as food for the good bacteria.
Soluble fibers can also help you to feel full longer. They are thought to absorb liquid in the intestines, slowing the absorption of nutrients and resulting in feelings of satiety.
Found in: beans, Brussels sprouts, avocado, sweet potato and broccoli
