ESSENTIAL FATTY ACIDS
What are essential fatty acids or EFAs?
Essential fatty acids (EFA) refer to a group of fatty acids that the body can not produce and which must be ingested through food or supplements.
They differ from non-essential ones (saturated and monounsaturated fatty acids), beacuse the lattercan be obtained by the organism from proteins, carbohydrates or alcohol)
Types of essential faty acids
There are two types of essential fatty acids:
- Essential fatty acids omega-3 (linolenic acid): Among these we have the ones from vegetable origin, such as alpha-linolenic acid (ALA) which is derived from seed oils or vegetable with dark green leaves, such as linseed oil or purslane, respectively.
Among those of animal origin, the most important are those from blue of cold water fish such as salmon, tuna, sardines, mackerel, etc. The most prominent in this group are eicosapentaenoic acid (EPA)and docosahexaenoic acid (DHA).
The body transforms the first group into the second group. (More information about this component in the listing above)
- Essential fatty acids omega-6 (linoleic acid): In this group the most important element is gamma-linolenic acid (GLA). It can be found in the seed oil and black currant (cassis oil), borage or evening primrose. Valerian, borage contain much of the same principle in every part of the plant.
