According to "science", apple cider vinegar should have virtually no value. But such is surely not the case.
Actually science can back the benefits of ACV. Science knows that acids, including mild organic acids like ACV kill many pathogens. It is also known that acids control Candida. Both of these can be evidenced by the fact that acetic acid (vinegar) is one of the acids produced by the flora to control Candida and various pathogens. Science also knows that the acid can be used as a substitute for stomach acid to aid in digestion and absorption. Science also knows that acetic acid can be reacted with less absorbable mineral oxides and carbonates to aid in their absorption. Science also knowns that raw ACV is rich in B vitamins that are also beneficial to the body.
