Re:
Stay on-topic, James. Chocolate is just one of a long list of things that can trigger acid reflux, but that's not what the OP was asking.
"HV is right candida can produce ammonia or aceteylhyde which can contribute to acid reflux." Where did HV ever say this?? (nowhere)
You're missing the theory completely. Two of the products of fermentation are lactic acid (which burns just like HCl) and CO2. The LES gets forced open as the gas escapes and a little acidic bubble splashes onto the esophagus.
"The reason why Apple cider vinegar might help people is it might help to nuetralize some of the ammonia or other gases that candida/bad bacteria produces."
Dude, your way off base. First of all, in the people that it's helping, vinegar is not neutralizing "ammonia or other gases*" thus leading to relief from heartburn. Ammonia is basic, not acidic, as in "acid reflux." What's most likely happening is that the acidity of the vinegar is beating back the candida, diminishing the fermentation. Plus it has minerals which probably help. Though in general, people w/ candida should avoid it due to the yeast remnants and mycotoxins.
*Is it even possible for a liquid to neutralize a gas? (is it even possible to have "ammonia gas" in the stomach)?
Try not to post just for the sake of posting.
