text: Vinegar in the diet goes back well over 3000 years. The Roman army issued it to it's troops. Egyptians also used it in their diet even before that..I don't know what it does but I was raised half my life on a farm by an Aunt and Uncle..I have learned many things from them over the years.(Old remedies and such) My Uncle gets up every morning and and drinks a mixture of Cranberry apple juice with a tblspn of Apple cider vinegar in it...
