What are essential fatty acids?

Essential fatty acids are specific types of polyunsaturated fats that are crucial for maintaining overall health but cannot be produced by the human body. Therefore, they must be obtained through diet. These fatty acids are vital for various bodily functions, such as forming cell membranes, producing hormones, and supporting brain function.

There are two primary types of essential fatty acids: omega-3 and omega-6 fatty acids. Since they are not synthesized internally, their absence in the diet can lead to deficiencies and health issues. Foods rich in these essential fats include fish, flaxseeds, walnuts, and certain oils.

The other options focus on different types of fats or imply that some fats can be synthesized by the body, which does not align with the definition of essential fatty acids.
