If apple cider vinegar fixes your heartburn, your heart burn is not what you think it is.
Apple cider vinegar is an acid, so adding an acid to an acid problem should make it worse, but it doesn't... That's because the "heart burn" is actually caused by low stomach acid. Low stomach acid causes your food to not digest and instead ferment in your stomach.. So it bubbles up, gives off nasty gas and feels like heartburn.. but its not.. It's a lack of acid, not too much acid..
This is what happened to me.. and it's simply made worse by using ant acids... your problem is not enough acid, so reducing the acid even more just makes more long term problems.. Adding acid (like apple cider vinegar is the soluntion..
Couple things that help...
-diet... there's just somethings that don't digest well and tend to ferment like breads..
-another HUGE one I had to learn is that your stomach is a bag, not an endless pit.. You never want to fill that bag up because it puts the contents of the bag closer to the top (and sometimes out).. So small meals are better..
-because your bag is a limited size AND your acid in your stomach is supposed to be a certin strength, don't drink liquids while eating or after eating.. Liquids dilute your stomach acid making it harder for your stomach to break down the food before it ferments.. I have a tiny tiny bit of water with my meals if I need it.. otherwise I wait until my foods well on its way to being digested.. You can actually feel this if you eat a meal for lunch with no liuids.. then tomorrow eat the same meal, but drink a large glass of water with it.. you'll see the one with no liquid digests a lot faster and easier...
