There are endless benefits to using Apple Cider Vinegar, some proven and some not proven...here are a few:
It promotes stable blood sugar.
You know that light-headed, low-energy feeling you sometimes get after chowing down on too many refined carbs? That’s your blood sugar spiking—and then crashing down. The acetic acid found in ACV (and most other types of vinegars, like white vinegar and red wine vinegar) contains anti-glycemic properties, and studies show that consuming apple cider vinegar before a meal can help keep those kinds of spikes at bay. This could, in theory, have something to do with why people who take ACV claim that the stuff boosts their mood and energy.
It can fight bacteria.
ACV has been used to combat infections like ulcers and sores since the time of the ancient Greeks. In fact, there are plenty of studies documenting vinegar’s antimicrobial effects. But just because ACV is capable of fighting bacterial infections doesn’t mean that using it to do so is actually a good idea. Because it’s so acidic, pouring it into your ears for an ear infection or using it on open sores or cuts is almost guaranteed to irritate your skin. It’s not safe to use by itself for a sore throat, either, because it could do more harm than good.
It improves your skin.
Anecdotally, there are plenty of people who say that applying ACV to their faces helps get rid of acne and improve their skin’s texture.
It whitens teeth.
ACV’s antibacterial properties could conceivably help get some plaque and germs off of your teeth.
Apple cider vinegar's acetic acid contains some beneficial properties, but in high concentrations, acedic acid can be a poison. So if you’re going to drink the stuff or use it on your skin, you’ve got to be careful.
The best way to use ACV is in tiny doses. If you’re drinking the stuff, swig a tablespoon diluted in at least eight ounces of water no more than twice a day. And always chase it with food, which can help clear the acid out of your throat faster and prevent irritation
The same principle applies if you want to try using it on your skin. Dilute a tablespoon of ACV in a bowlful of hot water and dunk a face towel or rag in the mixture.
Most of the research on apple cider vinegar has looked at its effects on blood sugar, and those studies seem to pan out. Experts accept that ACV has antibacterial properties too—but because vinegar is harsh, it’s not the best choice for treating sore throats or wounds (except those jellyfish stings). As for the other stuff, there’s no scientific data to support using ACV for better skin, less dandruff, or whiter teeth. What’s more, it might be harmful. If you decide to try using it anyway, proceed with caution.
