What are essential fatty acids?

Essential fatty acids are types of fats that the body cannot synthesize on its own and therefore must be obtained from the diet. These fatty acids play crucial roles in various bodily functions, including cell membrane structure, hormone production, and the reduction of inflammation. The two primary types of essential fatty acids are omega-3 and omega-6 fatty acids, which are found in foods such as fish, nuts, seeds, and certain oils.

Fats produced in the body do not fall into the category of essential fatty acids, as these are synthesized by the liver and other tissues. Saturated fats and trans fats are not essential fatty acids either; they can have detrimental health effects in excess and are typically not required by the body for optimal functioning. Thus, focusing on dietary sources is key for ensuring adequate intake of essential fatty acids.
