Perhaps the two good fats have different biological effects, Hu said. "Bad" fats include trans fats and saturated fats. In fact, the study found that if people replaced a mere 5% of their calorie intake from "bad" fats with polyunsaturated fats, they could reduce their risk of death by 27%. Hu and his colleagues found that although eating more saturated fat and trans fats was associated with an increase in mortality, eating more polyunsaturated and monounsaturated fats lowered the risk of death. Polyunsaturated fats contain essential fats your body can't produce by itself, such as omega-6 and omega-3 fatty acids.
