I've spent about a month doing research for an article about ACV and gout. The thing I found most curious was the total lack of scientific research on ACV. other than basically anecdotal evidence on natural health remedy sites, I could not locate any solid, peer reviewed papers - positive or negative about the curative properties of ACV.

I was an investigative environmental journalist for almost twenty years, and used Pubmed along with other related sites extensively in background research, and I was amazed to find the paucity of data in light for all the health benefit claims made and the overwhelming anecdotal testimonials supporting those claims.

It would seem to me that some scientific researcher would take up the challenge and prove or disprove ACV has any medicinal properties. However, at present from the scientific perspective, there is no proof one way or the other. Consequently, the study you cited doesn't prove anything except that one should dilute ACV before drinking.

Possibly, I should stop using vinegar for cooking and a general condiment?

Maybe they should put warning labels on mustard, mayonnaise, and salt and vinegar chips.

of course medicine would not endorse it why would they , they cant patient it they cant market it & they cant make millions of dollars from it i guess you just have totrust the people that use it & gain good health.
So you didnt find any info on the vitamin & mineral break down of the ninety or so that are. Which apple cider vinegar are you talking about the pure one or the one that is filtered of all it's goodness & is as transparent as glass
, i wouldn't touch that one either.
Many people discount the bible too but from that point of view we will one day have the proof of it's voice!

if some one were to drink it straight, i say just deserves, common sense must prevail!
