Essential fatty acids, or EFAs, are fatty acids that are required by humans and other animals for normal physiological function that cannot be synthesized in the body. [1] [2] As they are not synthesized in the body, the essential fatty acids – alpha-linolenic acid (ALA) and linoleic acid – must be obtained from food or from a dietary supplement.
The proportion of omega-3 to omega-6 fatty acids in a diet may have metabolic consequences. [2] Unlike omega-3 fatty acids and omega-6 fatty acids, omega-9 fatty acids are not classed as essential fatty acids because they can be created by the human body from monounsaturated and saturated fatty acids, and are therefore not essential in the diet.

It’s high in protein and omega-3 fatty acids and low in saturated fat. The American Heart Association recommends eating two servings of fish every week, especially fatty fish like salmon.

The Burrs coined the phrase "essential fatty acids". [14] Since then, researchers have shown a growing interest in unsaturated essential fatty acids as they form the framework for the organism's cell membranes. [15] Subsequently, awareness of the health benefits of essential fatty acids has dramatically increased since the 1980s. [16]
Nonetheless, processed foods tend to have an inferior nutritional profile compared to whole, fresh foods, regarding content of both sugar and high GI starches, potassium/sodium, vitamins, fiber, and of intact, unoxidized (essential) fatty acids. In addition, processed foods often contain potentially harmful substances such as oxidized fats and ...
Fatty acids that are required for good health but cannot be made in sufficient quantity from other substrates, and therefore must be obtained from food, are called essential fatty acids. There are two series of essential fatty acids: one has a double bond three carbon atoms away from the methyl end; the other has a double bond six carbon atoms ...
