You're probably thinking of the MCTs in coconut oil, which do seem to offer some health benefits, but coconut oil is also monstrously high in saturated fats (90% vs 14% for olive oil), and tons of studies show that saturated fat is relatively awful for the human body.

Coconut and palm oils are the least healthy of all the vegetable oils. In terms of saturated fat, they're almost as bad as beef fat.
