This book and Jarvis' other book on "Arthritis" should be read together. They cover the same topic and are complementary. Both record this classically trained M.D.'s experience coming to grips with and subsequently proving to his own satisfaction, the wisdom of Vermont Folk Medicine.
All the other books have hardly any value besides telling you how to use vinegar for disinfecting, cleaning and household tasks (which are good, but secondary in my opinion). What little value they MIGHT have is because they have read and either quoted or plagiarized Jarvis. Sometimes because these people know more about typing than science, their statements on one hand present Jarvis' concepts then contradict it a few pages later by quoting some unproven babble.
While I don't think his work is the end all of nutrition, I wish I had ten times as much information from his pen and notes as "fodder" for interacting with other nutritional studies.
Unless you just want to know how to use vinegar to wash windows, these are the only "Apple Cider Vinegar" books I reccommend that I've seen on Amazon.
There is one exception to this rule. You might also want Natural Healing with Cider Vinegar by Hellmiss too. These three are "IT". The rest will at best duplicate what you can get in these books or at worst, babble on incessantly. Mindell, while a top health writer, offers only a booklet with nothing much more to add to these three works. One topic Jarvis didn't address was the difference between the old fashioned apple cider vinegar which had many vital components retained and the filtered stuff which has been cleaned up to look nice but is the bottled equivalent of white flour... the good stuff has been taken out.
Buy Jarvis, read the books and put the information to work!
