Mixed EFAs™ A carefully designed blend of seed and nut oils that includes walnut oil, sesame seed oil, apricot kernel oil and hazelnut oil Functions of Unsaturated Fatty Acids Dietary double bonds in the Polyunsaturated Fatty Acids (PUFA) N-6 family, linoleic acid Dietary PUFA supply essential fatty acids, (EFAs). EFAs is designed as a dietary fall into two broad categories, N-6 and N-3. The ratio of essential fatty acid. Linoleic N-6/N-3 is an important consideration in establishing acid is converted to gamma N-3 requirements. Animal products differ with respect to linoleic acid (GLA, C18:3n-6) prevalence of N-6 and N-3 PUFA. Marine animals, marine via delta 6 desaturase. GLA algae and certain seed oils are enriched in N-3, while meat is elongated to dihomo GLA and cooking oils, such as corn oil and safflower oil, contain (C20:3n-6), then a fourth primarily N-6 PUFA. In contrast, the typical Western double bond is created by diet supplies 10-fold or more N-6 PUFA than N-3, and delta 5 desatura s e, yielding the single most common PUFA in such a diet is linoleic the eicosanoid precursor, acid with 18 carbons and 2 double bonds (designated arachidonic acid, C20:4n-6. (1) as C18:2n-6). It is metabolized to longer chain PUFA N-3 PUFA by the body. It is estimated that 20 g linoleic acid/day These fatty acids possess would supply 1 g or more/day of gamma linoleic acid a double bond at the 3rd and higher metabolites via metabolism. Arachidonic acid carbon atom of the fatty acid (C20:4n-6) is the most abundant metabolite of linoleic chain. The simplest member acid in most foods; especially meats, eggs and seafood. of this family, alpha linoleic American diets supply between 50-600 mg arachidonic acid (ALA), C18:2n-3, is considered a second essential fatty acid daily, depending on the amount of meat and dairy acid, due to the body’s inability to create unsaturated products consumed. fatty acids at the 3 position of the fatty acid chain. Delta Human plasma reflects dietary intake and typically 6-and delta-5 desaturases and elongases convert ALA contains the following average concentrations: to eicosapentaneoic acid (C20:5n-2, EPA) and this is the linoleic acid 1500 mg/L; gamma linoleic acid 25 mg/L; preferred substrate for these enzymes. dihomogamma linoleic acid 100 mg/L and arachidonic Polyunsaturated Fatty Acids (PUFA) fo r Membrane (2) acid 400 mg/l.

Conversely, low levels of adipose tissue Diets rich in monounsaturated fatty acids (primarily oleic linoleic acid increase the risk of coronary heart disease acid) can lower serum cholesterol and LDL-cholesterol and related mortality.(4) In addition, N-6 PUFA affects other levels, especially when substituted for high levels of risk factors for cardiovascular disease, such as platelet saturated fats.(7) There is an inverse association between aggregation and hypertension.(4) A diet that is high in increased consumption of monounsaturated fat and N-6 PUFA depresses all lipoprotein fractions, including decreasing risk of stroke.(8) A second advantage is that HDL, which is protective against coronary heart disease.(4) oleic acid does not lower HDL levels.
