If saturated and trans fats do not add up to total fats, what are the remaining fats?

Unsaturated fats: The remaining fats are unsaturated fats. Trans fats are very toxic and should be avoided as much as possible. Most saturated fats are unhealthy, though smaller saturated fats like lauric acid in coconut oil are not unhealthy. Other fats are monounsaturated and polyunsaturated fats, which are relatively healthy but can become less healthy when heated.
