Abstract (sommario):

Abstract Objectives Dietary lipids have a very important role in nutrition and must be ingested in an appropriate proportion. Objective: To study the effect of w3 fatty acid supplementation of a diet containing sunflower oil (rich in fatty acids omega 6) as fat source, on serum fatty acid profiles of growing rats. Methods Weanling Wistar rats received during 10 days normocaloric diet and fat was provided by sunflower oil (S group). The others groups received the same diet supplemented with 24mg/day of fish oil (SF group) or chía oil (SCh group). Control group (C) received AIN´93 diet. Serum fatty acids profiles were determined by gas chromatography. Statistical analysis used ANOVA test. Results Results: (expressed as %Area) SERUM: OLEIC C:10.11 ± 1.84, S:12.13 ± 3.84, SCh:12.74 ± 1.56, SF: 13.12 ± 2.82; ARACHIDONIC C:13.40 ± 4.39, S:17.61 ± 4.09, SCh: 15.75 ± 0.89, SF:15.41 ± 1.76; LINOLEIC C:20.52 ± 3.37, S: 19.80 ± 3.36, SCh: 21.14 ± 2.12, SF: 18.92 ± 3.87; LINOLENIC (ALA) C:0.93 ± 0.27a, S:0.19 ± 0.06 b, SCh: 0.28 ± 0.08b, SF:0.22 ± 0.05b; EPA C:0.80 ± 0.22, S:0.68 ± 0.15, SCh: 0.74 ± 0.18, SF: 0.67 ± 0.14; DHA C:1.60 ± 0.55a, S:1.14 ± 0.35a, SCh:1.70 ± 0.45a, SF:4.22 ± 0.93b. Media that didn't present a letter (a, b) in common, were different (p < 0.01). In sera, S, SF and SCh groups showed lower ALA levels compared to C. SF group presented high levels of DHA. Diet S was mainly a contributor to linoleic acid with a ratio w6/w3 = 250 (recommended value: 5–10). Conclusions The diet containing sunflower oil as fat source shows that ω6 family route was exacerbated; by the other hand ω3 family was depressed. Chia supplement showed a tendency towards higher values of w3 family but were significantly lower than C. Fish oil supplement increase significantly DHA values. Diet containing sunflower oil as fat source provoked changes in serum fatty acids profiles and the supplementation with w3 fatty acid provided by chía or fish oil do not increase ALA values significantly. Diet influences the serum fatty acid profile, being not only important the percentage of lipids on it but also the different fatty acids pattern. Funding Sources UBACyT: 20020190100093BA.

Abstract (sommario):

Objective: To review the role of essential fatty acids in brain membrane function and in the genesis of psychiatric disease. Method: Medline databases were searched for published articles with links among the following key words: essential fatty acids, omega-3 fatty acids, docosahexanoic acid, eicosapentanoic acid, arachidonic acid, neurotransmission, phospholipase A2, depression, schizophrenia, mental performance, attention-deficit hyperactivity disorder, and Alzheimer's disease. Biochemistry textbooks were consulted on the role of fatty acids in membrane function, neurotransmission, and eicosanoid formation. The 3-dimensional structures of fatty acids were obtained from the Web site of the Biochemistry Department, University of Arizona (2001). Results: The fatty acid composition of neuronal cell membrane phospholipids reflects their intake in the diet. The degree of a fatty acid's desaturation determines its 3-dimensional structure and, thus, membrane fluidity and function. The ratio between omega-3 and omega-6 polyunsaturated fatty acids (PUFAs), in particular, influences various aspects of serotoninergic and catecholaminergic neurotransmission, as shown by studies in animal models. Phospholipase A2 (PLA2) hydrolyzes fatty acids from membrane phospholipids: liberated omega-6 PUFAs are metabolized to prostaglandins with a higher inflammatory potential, compared with those generated from the omega-3 family. Thus the activity of PLA2 coupled with membrane fatty acid composition may play a central role in the development of neuronal dysfunction. Intervention trials in human subjects show that omega-3 fatty acids have possible positive effects in the treatment of various psychiatric disorders, but more data are needed to make conclusive directives in this regard. Conclusion: The ratio of membrane omega-3 to omega-6 PUFAs can be modulated by dietary intake. This ratio influences neurotransmission and prostaglandin formation, processes that are vital in the maintenance of normal brain function.

Abstract (sommario):

Abstract Literature data show that the relationship between two groups of polyunsaturated fatty acids in diet, omega 3 acids, whose basic representative is a-linolenic acid (C18: 3 n-3), and omega 6 acids, whose basic representative is linoleic acid (C18: 2 n-6), has a significant role in development of cardiovascular diseases in humans. The optimal ratio of omega 6 to omega 3 fatty acids is around 4:1. In monogastric animals, the fatty acids in feed are absorbed in the gastrointestinal tract largely unchanged. This means the fatty acid profile of the animal’s diet directly reflects the fatty acid profile of the tissue. The daily intake of unsaturated fatty acids can be increased by an adequate animal nutrition strategy. Flaxseed contains ten times more unsaturated (32.26%) than saturated (3.66%) fatty acids. The largest amount of unsaturated fatty acids (about 70%) is a-linolenic acid (ALA), which is a precursor of the entire omega 3 series of fatty acids, and which makes flaxseed an ideal raw material for the production of a wide range of omega 3 enriched products. In order to obtain chicken meat rich in omega 3, an experiment was organized with a specific diet for broilers at fattening. Thanks to the designed animal feed, it was possible to get products (meat, breast, drumstick, liver, subcutaneous fat) with significantly higher amounts of omega 3 fatty acids compared to the same products obtained from broilers fed with conventional mixtures, or with almost the ideal ratio between omega 6 and omega 3 fatty acids.

Abstract (sommario):

Omega-3 long-chain polyunsaturated fatty acids (?-3 LC-PUFAs) are thought to be important for normal dopaminergic, glutamatergic and serotonergic neurotransmission. Depression is less prevalent in societies with high fish consumption, and depressed patients have significantly lower red blood cell ?-3 levels. Studies with ?-3 supplementation have led to controversial results. A significantly longer remission of bipolar symptomatology has been confirmed from a high-dose DHA and EPA mixture. Greater seafood consumption per capita has been connected with a lower prevalence of bipolar spectrum disorders. Reduced levels of ?-6 and ?-3 PUFAs were found in patients with schizophrenia.

Abstract (sommario):

Purpose: This article will summarize the current evidence on the effects of omega-3 fatty acids on prevention and treatment of mental illness. Background: Omega-3 fatty acids are involved in many physiologic processes. Since they cannot be made de novo in the body, they are considered essential nutrients. As the Western diet evolved, dietary intake of fatty acids has shifted to increased omega-6 fatty acids and decreased omega-3 fatty acids intake. These changes have been correlated with numerous differences in prevalence and course of mental illnesses. Methods: A MEDLINE search from 1966 to December 2010 was completed to identify studies comparing changes in symptoms, functioning, other outcomes, and/or side effects in patients treated with omega-3 fatty acids for mental illness. The studies were reviewed and reported by specific psychiatric disorder studied. Conclusions: Omega-3 fatty acids play a role in many biologic functions. Epidemiologic data implicate omega-3 fatty acid deficiencies in many mental illnesses. Data are most robust for omega-3 fatty acids' role in affective disorders. However, data are conflicting, negative, or absent for most mental illnesses.

Abstract (sommario):

Omega-3 fatty acids, especially long-chain omega-3 fatty acids, have been associated with potential health benefits for chronic disease prevention. Our previous studies found that dietary omega-3 fatty acids could accumulate in the meat and eggs in a duck model. This study was to reveal the effects of various dietary fats on fatty acid profile and conversion of omega-3 fatty acids in duck liver. Female Shan Partridge Ducks were randomly assigned to five dietary treatments, each consisting of 6 replicates of 30 birds. The experimental diets substituted the basal diet by 2% of flaxseed oil, rapeseed oil, beef tallow, or fish oil, respectively. In addition, a dose response study was further conducted for flaxseed and fish oil diets at 0.5%, 1%, and 2%, respectively. At the end of the five-week treatment, fatty acids were extracted from the liver samples and analyzed by GC-FID. As expected, the total omega-3 fatty acids and the ratio of total omega-3/omega-6 significantly increased in both flaxseed and fish oil groups when compared with the control diet. No significant change of total saturated fatty acids or omega-3 fatty acids was found in both rapeseed and beef tallow groups. The dose response study further indicated that 59–81% of the short-chain omega-3 ALA in flaxseed oil-fed group was efficiently converted to long-chain DHA in the duck liver, whereas 1% of dietary flaxseed oil could produce an equivalent level of DHA as 0.5% of dietary fish oil. The more omega-3 fatty acids, the less omega-6 fatty acids in the duck liver. Taken together, this study showed the fatty acid profiling in the duck liver after various dietary fat consumption, provided insight into a dose response change of omega-3 fatty acids, indicated an efficient conversion of short- to long-chain omega-3 fatty acid, and suggested alternative long-chain omega-3 fatty acid-enriched duck products for human health benefits.
