The human body can synthesize a variety of fatty acids, but linoleic acid (ω-6 series) and α-linolenic acid (ω-3 series) cannot be synthesized and must be provided by food, so they are called essential fatty acids. After α-linolenic acid is metabolized in the body, it is converted into docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA). Linoleic acid is very abundant in vegetable oils such as soybean oil, corn oil, and sesame oil, and is generally not easily deficient. Alpha-linolenic acid is primarily found in plant foods, while DHA and EPA are primarily found in animal foods (fatty green-skinned fish) and algae. The food with the highest alpha-linolenic acid content is perilla seed oil, followed by flaxseed oil.
