Apple cider vinegar, otherwise known as cider vinegar or ACV, is a type of vinegar made from cider or apple must and has a pale to medium amber color. Unpasteurized or organic ACV contains mother of vinegar, which has a cobweb-like appearance and can make the vinegar look slightly congealed. It reduces blood cholesterol levels and heart-disease risk. Apple cider vinegar fans say it contains pectin, which attaches to cholesterol and carries it out of the body, thus decreasing the risk of heart disease. In addition, many vinegar proponents say it is high in potassium, and high-potassium foods play a role in reducing the risk of heart disease by helping to prevent or lower high blood pressure.
