I hve been drinking 1 tablespoon Apple Cider Vinegar twice a day for nearly a year. My health is good, my skin feels best while drinking this. I dilute it some and drink it through a straw to bypass my teeth. However when testing my urine with a ph strip in the a.m., I am high on the acid side; 5.5. Sometimes during the day that number will climb to a 6.5 or 7. Sometimes it stays the same. Why aren't I getting an akaline/normal reading? Thanks.
