Cellulose (plant fiber)
Fiber is the indigestible portion of plant foods. There are two types; soluble which is fermented in the colon into gases and active byproducts, and insoluble which is metabolically inert that absorbing water as it moves through the digestive system. Fiber isn't considered a nutrient since it can't be digested by humans.
