There is medical evidence that apple cider vinegar can control certain ailments such as high blood sugar and reduce the risk of developing certain cancers. Further, folk medicine holds that it also treats acid reflux, acne, gout, varicose veins and heartburn, many of which are related to body pH levels.
According to “People Are Drinking Vinegar. Should You?” a 2004 study found that drinking apple cider vinegar before eating a high-carbohydrate meal slows the rise in blood sugar levels for people who are insulin resistant or have type 2 diabetes. A 2006 study found that consuming polyphenols such as those found in apple cider vinegar increases antioxidants while it may reduce cancer risk.
Although common sense says that apple cider vinegar must be acidic, it actually alkalizes. Because it can help restore the body’s pH balance in some individuals, apple cider vinegar can reduce acid reflux and heartburn. According to “Apple Cider Vinegar and pH Balance,” since apple cider vinegar has anti-bacterial, anti-fungal and anti-viral properties, many people use it as a disinfecting astringent to calm skin allergies. This may explain why people believe that its antioxidant qualities can treat gout, varicose veins and acne, ailments that have an inflammatory component.
