This book contains very useful information as to what most oils are comprised of and how exposing them to heat affects their chemical compositions. It also discusses very clearly how these oils are digested. High grade food oils are expensive and coconut oil is no exception. As a consumer, its wise to educate yourself as you can then make a more informed decision as to what oils you will cook with and ultimately ingest into your body.
One of the most surprising pieces of info I have found so far is the medium chain fatty acids in Coconut oil contains 6.7 calories versus 9 per gram in other fat sources ( including olive oil). Your body also processes these fats differently, they more directly converted into energy instead of being broken down and stored as fat throughout the body.
I have been cooking with coconut oil exclusively for about a month and have been very impressed with the results. I cook everything in it and you can substitute coconut oil for butter in many recipes. I will be posting more as I continue to experiment with my new favorite ingredient.
