Q. Can olive oil be used in cooking, or should it be used only for salads and other cold foods?
A. Alice H. Lichtenstein, director of Tufts’ HNRCA Cardiovascular Nutrition Laboratory, answers: “To my knowledge Italians have been using olive oil for centuries in cooking. There is no reason why it could not be used for cooking. Theoretically, olive oil would be more stable than a more unsaturated oil.”
