EFA is an acronym that stands for "essential fatty acids". Essential fatty acids are types of polyunsaturated fats that are necessary for the proper functioning of the human body but cannot be synthesized by the body itself. Therefore, these fatty acids must be obtained through the diet.
There are two main types of essential fatty acids: omega-3 and omega-6. Omega-3 fatty acids include alpha-linolenic acid (ALA), eicosapentaenoic acid (EPA), and docosahexaenoic acid (DHA). Omega-6 fatty acids encompass linoleic acid (LA) and arachidonic acid (AA).
EFA plays a vital role in many bodily functions. They contribute to the formation of cell membranes, help regulate blood clotting, support hormone production and function, and assist in the absorption of fat-soluble vitamins. Additionally, essential fatty acids are involved in the development and maintenance of the nervous system and brain.
A deficiency in essential fatty acids can lead to various health issues, including poor memory, dry skin, hair loss, reproductive problems, and impaired growth and development in children.
Sources of essential fatty acids include fatty fish (such as salmon and mackerel), flaxseeds, chia seeds, walnuts, soybean oil, sunflower oil, and canola oil. In some cases, EFA supplements may also be recommended.
In summary, EFA refers to essential fatty acids, crucial types of fats that the body cannot produce on its own. They are vital for optimal health, supporting various bodily functions, and can be obtained through a balanced diet or supplements.
