Ferments are bio catalysts, breaking down food as each of them is deeply specialized in assimilating a certain type of products. For instance, those ferments, responsible for breaking down sugars, have nothing to do with the assimilation of either starch or proteins. Ferments extract nutrients, being essential for the human body.

Digestion - a sequential process of breaking down carbohydrates, protein as well as fat by means of enzymes, consisting in saliva, gastric juice, pancreatic and intestinal juices and bile as well. Enzymes are also known as ferments, the biological role of which is to speed up the biochemical processes.
