Hmmm,
Organic vinegar such as apple cider vinegar is not acidic!


Well, if it isn't acidic, then it isn't vinegar. Vinegar is a weak
(~ 5%) solution of acetic acid in water. Some types may have
various "flavourings" in addition, but it is the acid that makes it
vinegar. High school chemistry class strikes again!

Hmmm,
When you have a heart burn due to too much stomach acid; acid refulux,
take some apple cider vinegar what happens? No heart burn! You can
tell from taste whether it is acidic or alkaline. Another example?
Orange is acidic, lemon is not.

How much bad information can one thread contain. Lemons ARE acidic. Apple
cider vinegar IS acidic. Heartburn is not caused by too much acid but the
acid being pushed above the stomach onto sensitive tissues. Many people
don't have enough acid in the stomach to digest properly, and that can cause
heartburn, taking antacids can feel better because of less acid to cause
pain, but will hinder proper digestion further.
