nutrition facts profileFiber is digestible, by our gut bacteria, who make short chain fatty acids out of it, which have a number of health promoting effects, such as inhibiting the growth of bad bacteria, increasing mineral absorption—for example, experimentally infused into the rectum of the human body, they can stimulate calcium absorption. So much so you can improve bone mineral density just by giving people the fiber naturally found in foods like onions, asparagus, and bananas. Our good bacteria also use fiber to maintain normal bowel structure and function, preventing or alleviating colonic-based diarrhea, and stimulating colonic blood flow up to five-fold, as well as fluid and electrolyte uptake.
