You guys are wrong. Back in the 1930s, Dr. Weston Price found South Pacific Islanders whose diets were high in coconut to be healthy and trim, despite high dietary fat, and heart disease was virtually non-existent. Similarly, in 1981, researchers studying two Polynesian communities for whom coconut was the primary caloric energy source found them to have excellent cardiovascular health and fitness. The first, extra-virgin olive oil is the best monounsaturated fat and works great as a salad dressing. However, olive oil should not be used for cooking. Due to its chemical structure, heat makes olive oil susceptible to oxidative damage. So for cooking, I use coconut oil exclusively. Nearly 50 percent of the fat in coconut oil is of a type rarely found in nature called lauric acid, a "miracle" compound because of its unique health promoting properties. Your body converts lauric acid into monolaurin, which has anti-viral, anti-bacterial and anti-protozoa properties.
And polyunsaturated fats, which include common vegetable oils such as corn, soy, safflower, sunflower and canola, are absolutely the worst oils to cook with.
