Oils rich in polyunsaturated
fatty acids (PUFAs) also provide essential fats that your body needs but can't produce itself, such as the omega-6 and omega-3 fatty acids.
What to do: Replace saturated fats (in foods like red meats, dairy, and butter) with polyunsaturated
fats (in foods like oils, fish, and nuts).
Interestingly, the investigators found that different subtypes of circulating long-chain omega-3 and omega-6 fatty acids had different associations with coronary risk, with some evidence that circulating levels of eicosapentaenoic and docosahexaenoic acids (two main types of long-chain omega-3 polyunsaturated
fatty acids), and arachidonic acid (an omega-6 fat) are each associated with lower coronary risk.
The study suggests that not all polyunsaturated
fatty acids are good for the heart.
