This is an oldie that keeps cropping up in the sphere of (completely unvetted) wellness tips – apple cider vinegar. I’m a bit puzzled by the claims that this is a “natural remedy.” Apples are natural. Cider is processed, as is vinegar, through a fermentation process involving bacteria and yeast that occurs on an industrial scale. It’s not magic. It’s chemistry.
Anyway, a Google search revealed top hits chock a block FULL of Woo Woo claims that are fantastical in nature and, you guessed it, not scientifically vetted. The “apple cider vinegar process” is only at the top because I searched for it first, I suspect. But the rest – “apple cider vinegar gummies” (gross!), “apple cider vinegar benefits” (makes foods taste yummo, but that’s it), “apple cider vinegar pills” (WTF?), “apple cider vinegar weight loss” (maybe if all you eat are salads with apple cider vinaigrette dressing – but that’s a sad way to live), and “apple cider vinegar diet” (that doesn’t even make sense) – it’s all a bunch of doo doo!
But, since I’m a debunker of woo woo scams, I’m doing the research. A PubMed (database of peer-reviewed published biomedical research) search using “apple cider vinegar” yielded 94 results. Aside from a few articles on the antimicrobial and anti-fungal properties of ACV (not surprising, considering that ACV contains 5-6% acetic acid) and studies in rodent models (cardiovascular health, obesity, and something about boosting immunity in carp and – those were weird) that may or may not translate to humans, most of the articles covered the dangers of using ACV as a “natural remedy.”
For example, tooth erosion and esophageal injury was documented in at least two studies [Case Reports Ned Tijdschr Tandheelkd. 2012 Dec;119(12):589-91. doi: 10.5177/ntvt.2012.12.12192 “Unhealthy weight loss. Erosion by apple cider vinegar”; J Am Diet Assoc. 2005 Jul;105(7):1141-4. doi: 10.1016/j.jada.2005.04.003. “Esophageal injury by apple cider vinegar tablets and subsequent evaluation of products.”]. Seriously, do NOT use this to treat heartburn or GERD. It’s a fucking ACID and adding ACID to a condition caused by escape of stomach ACID is completely ridiculous. Don’t drink it. Cook with it, but don’t drink it.
Not only does ACV have no benefit for atopic dermatitis [(skin irritation) Pediatr Dermatol 2019 Sep;36(5):634-639. doi: 10.1111/pde.13888. Epub 2019 Jul 22. Apple cider vinegar soaks [0.5%] as a treatment for atopic dermatitis do not improve skin barrier integrity], topical skin treatments with ACV can cause chemical burns [J Am Acad Dermatol. 2012 Oct;67(4):e143-4. doi: 10.1016/j.jaad.2011.11.934. “Chemical burn from topical apple cider vinegar.”]! Don’t put it on your skin. Please.
One study reported a lack of antiglycemic (lowering of blood sugar) by vinegar, including ACV, in humans [Nutr Res. 2009 Dec;29(12):846-9. doi: 10.1016/j.nutres.2009.10.021. “Vinegar lacks antiglycemic action on enteral carbohydrate absorption in human subjects.”]. So no, it won’t help people with diabetes.
Fun rando fact – apparently ACV attracts several species of fruit flies, so if you want to collect some wild ones as pest control or for DIY experiments at home, try it! I’m not citing these. Look it up yourself. There are a surprising number of studies documenting this.
Bottom line – there are no validated health benefits in humans for this “natural remedy,” but there are plenty of bad things that can happen if you drink a lot of cider vinegar, put it on your skin, or take pills (and presumably gummies).
And ACV does NOT cure or treat cancer. Only two references came up in a PubMed search for “apple cider vinegar cancer,” and neither reported any benefits for treatment of warts or moles, let alone skin cancer.
BUT…ACV can make tasty salad dressings and delicious sauces. One of my favorites for fall is apple glazed baked chicken. Here’s the recipe:
1 whole broiler chicken, apple jelly, apple cider vinegar, apple pie spice, apples (tart or sweet)
Preheat oven to 325 degrees. Season the chicken with olive oil, salt, and pepper. Bake chicken for 1 1/2-2 hours. While chicken is baking, slice apples and prepare glaze. To prepare glaze, heat 1/2 jar of apple jelly with an equal volume of apple cider vinegar and 1-2 teaspoons of apple pie spice. Boil until volume is reduced by 1/2. Remove chicken from oven, drain chicken stock (can be used to prepare some DELICIOUS rice), cover with glaze, and place apple slices around chicken in the baking dish. Cook another 1/2 hour or until chicken is done. Serve with rice or potatoes, green beans, and enjoy!
