The problem with pickle juice is it’s so high in sodium. If you don’t have high BP and you sweat a lot (exercise or work) then you should be okay with it. Good to replenish those salts before cramps set in.
Vinegar also helps with heart burn because it’s acidic. Something is eaten which causes the gut to kick it’s digestive juices into high gear which start coming back up the pipe. The vinegar helps this by giving those stomach acids a hand in digesting the offending pepperoni or whatever it is. Antacids do the opposite so the digestion of the pepperoni is then moved into the intestines. Not really a good thing to do very often. Once in a while doesn’t hurt.
I make my own fruit/veggie juice and bottle it but before I do I add some apple cider vinegar. Walmart sells it by the gallon for $4. I then drink one bottle a day with breakfast. I don’t know if it helps with losing weight but I do feel better as compared to when I run out and get too lazy to make more. Those slow juicing machines are the best. I just use apples and carrots; two of the least expensive items but sometimes add whatever strikes my fancy.
My wife has started drinking 2 tablespoons of Bragg's in eight ounces of cold water just before bed. Her blood sugar reading in the morning is averaging 75-100 points LESS...she is hoping it lowers her A1C.
