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.
