There is some controversy on sat fat vs unsat fat. There is evidence on both sides. I like that Dr. S recommends you use a mixture of fat sources. The key with olive oil is what type to use when. Use extra-light olive oil for cooking. This is also available cold-pressed. It has the fewest impurities, so you don't have the problem when you heat it. Extra virgin olive oil should not be heated. Just drizzle it on your salad or vegetables. This is stuff that can taste wonderful if you know what brands are good. My favorite is Bionaturae organic.
