Coconut oil has been shown to be a superior choice when it comes to cooking oils.  Its medium chain saturated fatty acids are able to be quickly metabolised for energy in the liver.  As a saturated fat it is more heat stable than other oils, when used in cooking it produces far less free radicals, which harm the body.  It has also been shown to boost metabolism.
