Supplements essential fatty acid

Hepatic steatosis usually is a result of excessive administration of carbohydrates and/or lipids, but deficiencies of carnitine, choline, and essential fatty acids also may contribute. Hepatic steatosis can be minimized or reversed by avoiding overfeeding, especially from dextrose and lipids.35,38 Carnitine is an important amine that transports long-chain triglycerides into the mitochondria for oxidation, but carnitine deficiency in adults is extremely rare and is mostly a problem in premature infants and patients receiving chronic dialysis. Choline is an essential amine required for synthesis of cell membrane components such as phospholipids. Although a true choline deficiency is rare, preliminary studies of choline supplementation to adult patients PN caused reversal of steatosis. 

Nutrition (regular intake of protein-rich foods or drinks and essential fatty acids supplemental vitamins and minerals)... 

The antisocial behaviour of young adults in prison was studied. Supplementation of the diet with capsules containing vitamins, minerals and essential fatty acids reduced antisocial behaviour in comparison with control subjects. A much larger study is currently being planned. 

There is some evidence that, in these patients, the interconversion between the polyunsaturated fatty acids is disturbed, which restricts the formation of eicosapentaenoic and docosahexaenoic acids. Such children are less likely to have been breastfed (breast milk contains these omega-3 fatty acids) they are more likely to suffer from allergies associated with essential fatty acid deficiency and also dry skin and hair and the membranes of the erythrocytes contain less omega-3 fatty acids compared with normal children. So far, the results of supplementation of the diet of these children with this disorder have not been conclusive. 

The psychiatric community, the lay press, and ads on the Internet have drawn attention to the role of essential fatty acids (EFAs) on neural development and on the treatment of mental illness. The EFAs are often referred to as omega-3 and omega-6 fatty acids, and include fish oil, flax seed oil, and evening primrose oil supplements. 

Linoleic acid and alpha-linoleic acid are essential fatty acids that are provided in any long-term parenteral nutrition by administering fat emulsions at least twice a week. Fatty acid deficiency is a common complication of severe end-stage liver disease. The ability of short-term intravenous lipid supplementation to reverse fatty acid deficiencies has been studied in patients with chronic liver disease and low plasma concentrations of fatty acids (914). Shortterm supplementation failed to normalize triglycerides.

Patients with primary chylomicronemia and some with mixed lipemia must consume a diet severely restricted in total fat—10-15 g/d, of which 5 g should be vegetable oils rich in essential fatty acids. Supplementation of fat-soluble vitamins should be given. 

Diets. Three basic diets were utilized (Table I), a 2% low fat diet (2% linoleic acid methyl esters), a 20% polyunsaturated fat diet containing 20% stripped corn oil, and a high saturated fat diet containing 18% coconut oil and 2% linoleic acid methyl esters to prevent an essential fatty acid deficiency (6 ). All diets were prepared to our specifications by ICN Life Sciences (Cleveland, OH) and analyzed both by ICN and our laboratory for fatty acids, antioxidants and some trace minerals. They are routinely stored in sealed plastic containers at 4°. Antioxidants when added (see Figure 2) were supplemented just prior to feeding and at 0.2% or 0.3% of the diet by weight as specified in each experiment. 

Burr and Burr reported in 1929 a new deficiency disease produced by the rigid exclusion of fat from the diet. 1 Rodents fed a fat-free diet showed reduced growth and reproductive failure, accompanied by two prominent changes in the skin, that is, increased scaliness and impaired barrier function.1,2 Reversal of the features of deficiency by administration of linoleic acid (LA), led to the concept of essential fatty acids (EFA) that cannot be synthesized by the higher animals.2 Similarities between the clinical features of EFA deficiency and atopic dermatitis led Hansen in 1937 to discover low blood levels of unsaturated fat in atopic children,3 and he later reported that EFA-deficient infants developed an eczematous rash, which responded to LA supplements.4 Several studies had previously examined a range of dietary oil supplements in atopic dermatitis,5-8 with generally reported benefit.

Ertas et al. (2005) investigated the potential effects of dietary supplementation by coriander seed (considered as a lipolytic and antioxidant compound) on carcass lipid composition of quails. Their aim was to reduce saturated fatty acid consumption and to increase essential fatty acids (particularly n3 unsaturated acids) in alimentation. Dietary supplementation by coriander seed affected the lipid composition of carcass greatly by decreasing saturated fatty acid (SFA) contents (palmitic and stearic acids) and by increasing monounsaturated and polyunsaturated fatty acid (MUFA and...

It is becoming more popular in the US for infant formula manufactures to add fish oils to fortify infant formulae with long-chain polyunsaturated fatty acids, which are critical in early child development because they are necessary for the formation of neural tissues and cells of vascular tissue, but are produced de novo at very low levels from the dietary essential fatty acids Ci8 2, m-3 and Cis 3, co-3. Typically, the long-chain fatty acids, doco-sahexaenoic acid (DHA C22 6) and arachidonic acid (AA C2o 4), were not added to infant formulae available in the US until recently. Many commercial infant formulae manufactures, including Wyeth, Ross and Mead Johnson, now produce infant formulae that are supplemented with DHA and AA. The level of DHA is approximately 0.32%, w/w of fat, and the level of AA is approximately 0.64% w/w of fat. Breast-milk naturally contains small amounts of these long-chain polyunsaturated fatty acids. 

Biotin deficiency and the functional deficiency associated with lack of holo-carboxylase synthetase (Section 11.2.2.1), or biotinidase (Section 11.2.3.1), causes alopecia (hair loss) and a scaly erythematous dermatitis, especially around the body orifices. The dermatitis is similar to that seen in zinc and essential fatty acid deficiency and is commonly associated with Candida albicans infection. Histology of the skin shows an absence of sebaceous glands and atrophy of the hair follicles. The dermatitis is because of impaired metabolism of polyunsaturated fatty acids as a result of low activity of acetyl CoA carboxylase (Section 11.2.1.1). In biotin-deficient experimental animals, provision of supplements of long-chain 6 polyunsaturated fatty acids prevents the development of skin lesions (Mock et al., 1988a, 1988b Mock, 1991). 

The relationship between vitamin E and the polyunsaturated fatty acids, including the essential fatty acids, is quite dose, ft has been said that, if the body did not need or use PUFAs, there would also be no need for itamin E. A dietary relationship exists between PUFAs and vitamin E. Greater intakes of PUFAs tend to increase the requirement for vitamin E. An increase in intake of PUFAs, however, does not necessarily mean that vitamin E supplements are needed, because the foods highest in PUFAs (vegetable oils are also good sources of vitamin E.

In EFA deficiency, oleic acid can be dehydrogenated to yield polyunsaturated fatty acids (PUFAs) that are nonessential and do not substitute for the essential fatty acids. One suchPUFA is 5,8,11-eicosatrienoic acid, which occurs in significant amounts in heart, liver, adipose tissue, and erythrocytes of animals fed diets deficient in EFAs but decreases after supplementation with linoleic or linolenic acids. Its appearance in tissues and plasma has been used in the assessment of EFA deficiency.
