5 Side Effects of Too Much Apple Cider Vinegar

By Brian Lemay 19 comments

– Apple cider vinegar is very popular in the natural healthy community, but some have raised concerns about its safety and side effects, so in this video I’m
gonna take a closer look. Number one, digestive side effects. Apple cider vinegar may cause
unpleasant digestive symptoms in some people. Studies have found that the acetic acid in apple cider vinegar
may decrease appetite and promote feelings of fullness, but these effects may be due
to an increase in indigestion. The people who consume a
drink 25 grams or 0.88 ounces of apple cider vinegar
reported less appetite but also significantly
greater feelings of nausea, especially when the vinegar was part of an unpleasant-tasting drink. Number two, low potassium
levels and bone loss. Now, there are no controlled studies here, but there was one documented case study of low blood potassium levels
and bone loss attributed to high doses of apple cider vinegar over a long period of time. A 28-year-old woman consumed
eight ounces or 250 mls of apple cider vinegar diluted in water on a daily basis for six years. She was admitted to the hospital
with low potassium levels and other abnormalities
in blood chemistry. She was also diagnosed with osteoporosis, which is a condition of brittle bones that is rarely seen in young people, normally only in elderly people. Her doctors believe that
the large daily doses of apple cider vinegar were responsible, causing minerals being
leached from her bones to buffer the acidity of her blood from having so much vinegar, which has such a high
amount of acid in it. Of course, I think this
instance is quite rare. The amount of apple cider vinegar that she was having is a lot more than most people would have in a day, and she was having it every
day for six years straight. Number three, erosion of tooth enamel. Acidic foods and beverages have been shown to damage tooth enamel. Soft drinks and fruit juices
have been more widely studied, but some research shows that acetic acid in vinegar may also
damage the tooth enamel. One case study concluded that a 15-year-old girl’s
severe dental decay was caused by consuming one cup, or 237 mls, of undiluted apple cider vinegar per day as a weight loss aid. Again, this is likely only a concern for those who have large quantities. Number four, throat burns. Perhaps unsurprisingly,
apple cider vinegar has the potential to cause
esophageal or throat burns. This is a sensitive area,
and vinegar is largely acid. That’s why researchers recommend vinegar to be considered a
potent caustic substance and should be kept in
child-proof containers. Number five, delayed stomach emptying. Apple cider vinegar helps
prevent blood sugar spikes by slowing down the
rate at which food moves from the stomach into the
lower digestive tract, so this effectively slows the absorption of sugar into the bloodstream. However, this effect may worsen
symptoms of gastroparesis, or delayed stomach emptying, which is a common condition in
people with type 1 diabetes. In gastroparesis, the nerves in the stomach
don’t work properly, so food stays in the stomach too long and is not emptied at a normal rate. For those with type 1 diabetes
who have gastroparesis, timing insulin can be really challenging because there’s an uncertainty between how long it’s gonna
take from eating the food to it being digested and the
sugar absorbed into the blood. So there you have it, to stay
safe and prevent side effects, it’s important to monitor
how much vinegar you consume and to be careful with how you take it. While a small amount
of vinegar can be good, more isn’t better and can
potentially even be harmful. Thanks for watching, make

Omg who in the heck would even be silly enough to drink ACV un diluted anyway šŸ˜³? Thatā€™s so bad and never ever should anyone of that. I have 1tbsp diluted in 8oz water, a squeeze of lemon juice and a dash of cayenne pepper, and I drink it through a straw. Havenā€™t had any issues and been doing this for years.

Do you have any scientific evidence to support your bone loss theory other than just one woman who overconsumed ACV? I don't see how you can draw that conclusion based on just one case of ACV abuse.

Yeah don't drink 8 ounces of ACV every day. I drink about 2 teaspoons of ACV one in the morning and night

that's why healthy people who dont have high cortisol or calcium levels take it.they have to increase potassium.I took it after my levels were low due to ant acid tablets.I won't drink it regularly but I will use it on salad dressings etc.that's overdose of acid cider vinager,and increase in potassium .it lowers calcium calcium carbonate is not hood either.he says to take potassium carbonate if too much.it causes anxiety and insominia too.

250ml a day my god that's a lot she likely had acidosis from all that acid. A couple spoonfuls once or twice a day in a drink should be enough if you get the good stuff.

I wanna fix acid reflux, and although I've been drinking 2 table spoons of acv for 6 months, it hasn't fixed. So I'm considering to increase the amount.

Start small amounts see how u do for a few weeks and increase slowly, I know it says 2 teaspoon but I wud start off with one see how u do with that, and if u add lemon either add more water or lessen how much acv u putting cause if u keep adding more to the same amount of water it making the drink more acidic
