Like all fats, coconut oil is a blend of fatty acids, and contains an unusual blend of both short and medium chain fatty acids. It is this unusual composition that may offer health benefits. Although coconut oil contains 92% saturated fat -- the highest amount of saturated fat in any fat source -- the saturated fat from coconut is mostly in the form of medium chain triglycerides (MCTs), which are metabolized differently than other saturated fats. Coconut oil contains lauric acid, a MCT also found in human breast milk. Lauric acid makes up about 50% of coconut oil and can inhibit the growth of microbes, such as bacteria, yeast, and fungi. The MCTs in coconut oil also have potential benefits for the brain, heart, and body composition.
