Is potato acid forming food or alkali forming food?

potatos are carbohydrates and primarily sugars which convert over time to starch. starch and sugar creates an acidic condition which counter intuitively needs an acid such as vinegar to create and alkaline condition in your body so eating a small green salad with a vinegar salad dressing will help stabilize blood sugar levels. I'd check out some diabetic web sites and ask in a science category like chemistry for more links.
