Dr. Barnard gives an overview of the worldwide diabetes epidemic and what causes diabetes. He asks viewers to imagine how a key works with a lock. If the lock is jammed with gum, the key won't work. Diabetes occurs when fat gums up cells, stopping insulin from working with cells. But there's reason to be optimistic. Dr. Barnard explains how building your meal with fruits, vegetables, grains, and beans can help prevent and reverse diabetes.
