According to the American Diabetes Association, 11 million Americans have diabetes, but only an estimated 6 million know they have it. Jack Palance narrates the 40-minute video on this disease that cannot be cured but can be controlled. Illustrations are well used to demonstrate how the diabetic’s system is unable to metabolize sugars and starches, which can lead to such complications as cardiovascular disorders, kidney failure and blindness. People of various ages with the condition talk about living with it, and medical experts explain how patients should plan meals, monitor their blood-sugar levels and administer insulin. Viewers would be better served with less history of the disease and more specific information. We are told, for example, that extremely high or low blood-sugar levels are medical emergencies for diabetics, but the symptoms are never identified. Aside from the rather ghoulish presence Palance suggests, the tone of the tape is upbeat. With constant care to balance diet, exercise and medication, diabetic people can lead normal lives. Other tapes in this series include Hypertension and AIDS. (Med-Ed Productions, $89.95 each; 800-526-7002)
