There is widespread misconception that coconut oil is bad for you because it is said to raise blood cholesterol and cause heart disease. The only "proof" is one four-decades old study. The study used hydrogenated coconut oil. It is now known that the process of hydrogenation creates "trans fatty acids" (TFAs), which are toxic entities that enter cell membranes, block utilization of essential fatty acids (EFAs) and impede cell functionality. TFAs also cause a rise in blood cholesterol. These substances are not present in natural coconut oil.
