apple cider vinegar during gm diet

Hi..I'm planning to start the gm Indian vegetarian version of the diet from Monday the 14th.Its all the more necessary now as I have done my lipid profile recently and my cholesterol's way too high..hopefully the diet works for me..also I'm in the habit of drinking 2 spoons of apple cider vinegar in one glass of warm water thrice a day..can this be continued during the diet? Awaiting ur reply..thanku
