Acid reflux too much or not enough acId

iv seen a few people question why vinegar is recommended for reflux . Iv just been reading an interesting post which might explain why ; 

Only about 1 in 10 people with acid problems actually do have too much stomach acid – the rest actually has insufficient stomach acids (hypochlorydia) or a different problem altogether such as a food intolerance.

So we should all try to determine our food intolerance?

I guess it's important to know if youv too much or not enough acid and then you can adjust your diet accordingly . 

I've watched a video where a doctor suggested this as well. He said if drinking a bit of apple cider vinegar with water helps with your symptoms then you have too little acid and if drinking aloe vera helps then you have too much acid.

This is very interesting. I always thought it is down to too much acid. How to determine this?

Despite me reading that I suggested that to my doctor who said she never heard of a case of too little acid ! 

Its a mine field of conflicting info !
