Improved digestibility. Unfermented soybeans are difficult to digest, partly due to the high amount of protein enzyme inhibitors and hard-to-digest sugar structures. During the fermentation process, the enzymes produced by the beneficial bacteria and other microbes break down, or predigest, the specific complex carbohydrates (sugars) found in soy and most other legumes. This process also renders the proteins more digestible and easier to assimilate than those
