There are many microorganisms and life forms that can make us sick, including viruses, bacteria and fungi. They reach the interior of our body through various means and cause a large number of different diseases and health problems. One of the best poperties of kefir is that it works as a wide spectrum antibiotic, with many components that help protect us from germs and fungi.
Not only do the probiotics and nutrients of kefir boost our immune system, but also some of them have a direct effect on germs, killing them before they can do us any harm. Perhaps the most relevant component of kefir is an insoluble polysaccharide (a type of sugar with high molecular weight that can travel in a watery medium without dissolving) called kefiran, that has powerful antibiotic and antifungal effects, especially against the fungus known as candida, which causes candidiasis.
