The purported health benefits of coconut oil have sparked debate in the medical community. Conventional dietary advice has been to limit coconut oil because it is rich in saturated fats, which have been associated with heart disease. However, recent research has indicated that not all saturated fats are equal — while certain types remain linked to an increased risk of heart disease, others may actually be beneficial to health.

Health Pros
Saturated fats fall into several subcategories and not all of them have the same biochemical effect in the body. The previous research that lumped all sources of saturated fats together as unhealthy is under scrutiny. Coconut oil happens to be abundant in lauric acid, a type of saturated fatty acid that — although it does raise cholesterol levels — mainly increases HDL, the healthy type of cholesterol that you want to be high. The chain length of saturated fats is another indicator of healthfulness. Coconut oil contains medium-chain triglycerides, which are used directly for energy by your body.

Health Cons
All types of oils contain approximately 120 calories per tablespoon; therefore, coconut oil is calorically dense. If you are trying to lose weight, oils are one of the foods to consider limiting in your diet. You body needs fats for good health — but getting them from whole foods like the whole coconut rather than its extracted oils will give you fiber and other nutrients missing from the oil. All forms of coconut are high in calories and should be consumed in moderation. Avoid partially hydrogenated coconut oils which are not natural and are associated with increased risk of several chronic diseases.

Oils and Heat
Heat, along with light and oxygen, can destroy the beneficial fats in some oils. Polyunsaturated fats are the most fragile and are not recommended for cooking. Coconut oil, being mainly a saturated fat, is able to withstand higher temperatures than other oils, making it one of the best oils for cooking. It also gives a delicious taste and superb texture to foods. Use organic extra-virgin coconut oil for the best quality.
