What is a common source of polyunsaturated fats (PUFA)?

Oily fish is a renowned source of polyunsaturated fats (PUFA), particularly omega-3 and omega-6 fatty acids. These fats are essential for various bodily functions, including brain health, cardiovascular health, and reducing inflammation. Oily fish such as salmon, mackerel, sardines, and herring are rich in these beneficial fats, making them an excellent dietary inclusion for those looking to increase their intake of polyunsaturated fats.

While other food sources mentioned may contain fats, they do not primarily provide significant amounts of polyunsaturated fats. For instance, butter is mostly composed of saturated fats; beef lard is high in saturated fats as well; and coconut oil is predominantly saturated fat. Thus, oily fish stands out as the best option for obtaining healthy polyunsaturated fats in the diet.
