fjölómettaðar

Fjölómettað is an Icelandic term referring to polyunsaturated fatty acids. These are fatty acids that contain more than one double bond in their hydrocarbon chain. This structural characteristic distinguishes them from monounsaturated fatty acids, which have only one double bond, and saturated fatty acids, which have no double bonds. Polyunsaturated fatty acids are an important class of dietary fats.

The most common types of polyunsaturated fatty acids are omega-3 and omega-6 fatty acids. These are considered essential fatty acids because the human body cannot synthesize them and they must be obtained from the diet. Omega-3 fatty acids, such as alpha-linolenic acid (ALA), eicosapentaenoic acid (EPA), and docosahexaenoic acid (DHA), are found in sources like fatty fish, flaxseeds, and walnuts. Omega-6 fatty acids, such as linoleic acid (LA) and arachidonic acid (ARA), are commonly found in vegetable oils, nuts, and seeds.

Polyunsaturated fatty acids play crucial roles in human health. They are integral components of cell membranes and are involved in various physiological processes, including inflammation, blood clotting, and brain function. A balanced intake of omega-3 and omega-6 fatty acids is generally recommended for optimal health benefits. Excessive consumption of certain types of polyunsaturated fats, particularly those rich in omega-6, without a sufficient intake of omega-3s, can potentially lead to an imbalance that may contribute to certain health issues.
