Abstract An important role in human nutrition is played by fats, both of plant and animal origin. Fats are a category of foods rich in liposoluble vitamins and fatty acids. They are widely used in nutrition, in cosmetics, in the content of creams as well as in pharmaceutical products, in the form of dietary supplements, such as capsules with oils rich in fatty acids and the addition of liposoluble vitamins. The objective of this paper was to study the content in vitamins and fatty oils of two vegetable oils (wheat germ and sea buckthorn oils) and an animal oil (fish oil). The results show that these oils are rich in liposoluble vitamins, omega-3 fatty acids and omega-6 fatty acids. Hence, these oils can be used successfully in daily nutrition as substitutes for synthetic vitamins.

Serum Homocysteine

Abstract. Background: Elevated homocysteine levels and malnutrition are frequently detected in hemodialysis patients and are believed to exacerbate cardiovascular comorbidities. Omega-3 fatty acids have been postulated to lower homocysteine levels by up-regulating metabolic enzymes and improving substrate availability for homocysteine degradation. Additionally, it has been suggested that prevention of folate depletion by vitamin E consumption decreases homocysteine levels. However, data on the effect of omega-3 fatty acids and/or vitamin E on homocysteine levels and nutritional status have been inconclusive. Therefore, this study was planned to examine the effect of combined supplementation of fish oil, as a source of omega-3 fatty acids, with wheat germ oil, as a source of vitamin E, on homocysteine and nutritional indices in hemodialysis patients. Methods: This study was a randomized, double-blind, placebo-controlled trial. Forty-six hemodialysis patients were randomly assigned to two equally-sized groups; a supplemented group who received 3000 mg/day of fish oil [1053 mg omega-3 fatty acids] plus 300 mg/day of wheat germ oil [0.765 mg vitamin E], and a matched placebo group who received placebo capsules for 4 months. Serum homocysteine and different nutritional indices were measured before and after the intervention. Results: Twenty patients in each group completed the study. At the end of the study, there were no significant changes in homocysteine levels and in the nutritional indices neither in the supplemented nor in the placebo-control groups (p > 0.05). Conclusions: Fish oil and wheat germ oil combination did not produce significant effects on serum homocysteine levels and nutritional indices of hemodialysis patients.

Omega-3 fatty acids (Alpha-linolenic acid) and omega-6 fatty acids (Linoleic acid) are a group of essential fatty acids. Essential fatty acids are fatty acids that cannot be synthesized by the body so that must be supplied from the diet. One of the sources of essential fatty acids is derived from fish oil. This study aims to determine the effect of Crude Fish Oil (CFO) in the feed to EPA and DHA content in penaeid shrimp meat. The research method used was a completely randomized design. The treatments used are the varying content of Crude Fish Oil (CFO), which are P0 (0%), P1 (2%), P2 (4%), P3 (6%), and P4 (8%). The results of the study showed significant differences (p <0.05) on the content of EPA and DHA in penaeid shrimp meat. The highest content of EPA and DHA found in P4 treatment (8%) and the lowest at P0 treatment (0%). The use of CFO in penaeid shrimp feed need further study related to the growth of shrimps and prawns reproductive cycle to increase the productivity of penaeid shrimp. CFO on feed should be used at a dose of 6%.

Triglyceride Structure

Background and Aim: Numerous studies have found benefits of omega-3 polyunsaturated fatty acids (PUFAs), namely, for eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) in dogs. The objective of the present study was to assess the efficacy of dietary inclusion of equal amounts of omega-3 FAs in phospholipid (PL) from krill meal to triglyceride structure from fish oil to increase the omega-3 FA profile in red blood cells (RBCs) in dogs. Materials and Methods: Ten adult Alaskan Huskies of both genders were supplemented with daily 1.7 g EPA and DHA from krill meal for 6 weeks, while another ten dogs received 1.7 g EPA and DHA from fish oil. FA and omega-3 index measurements of the two groups were taken after 0, 3, and 6 weeks for comparison. Results: It was mainly the EPA levels that increased in the krill meal group (from 1.84% to 4.42%) compared to the fish oil group (from 1.90% to 2.46%) (p<0.001), which drove the group differences in the omega-3 index. This resulted in the krill meal group having a mean omega-3 index increase from 3.9 at baseline to 6.3%, which was significantly greater than the increase from 3.9% to 4.7% observed in the fish oil group (p<0.001). Concomitantly, omega-6 PUFAs, such as arachidonic acid and linoleic acid, were reduced in RBC membranes and the omega-6 to omega-3 ratio was significantly more reduced in the krill meal compared to the fish oil group. Conclusion: The results showed that krill meal supplementation was associated with a reduction of omega-6 PUFAs, which compensated for the increased omega-3 index, suggesting that PLs are efficient delivery molecules of omega-3 PUFAs.

SummaryNutritional manipulation of diets for layers can help to naturally modify the nutritional content of eggs. The objective of this study was to increase the concentration of the omega-3 fatty acid, docosahexaenoic acid (DHA), in the egg yolk by feeding a diet rich in omega-3 fatty acids from microalgae compared to one containing fish oil to layers. A total of 480 layers (Babcock B308) aged 28 weeks old were divided into four treatment groups with four replicates per treatment. The layers were fed a control diet, a diet containing 4% crude salmon oil, or microalgae (Schizochytrium spp.) at 1% or 2% in the diet for eight weeks. Feed intake and egg production were recorded daily and egg quality tested every two weeks. There were no significant differences between the control and treatment groups as regards feed intake, egg production, egg weight, egg mass, albumin height, and Haugh unit of the eggs. The egg samples were obtained at the start of the trial, four weeks and eight weeks for the analysis of the fatty acid profile in the eggs. The DHA level in the eggs from layers fed even 1% or 2% algae was higher (P < 0.05) compared to the level from those fed with the control diet and 4% fish oil supplementation. The omega 6:3 ratio in eggs was significantly reduced (P < 0.05) compared to the control diet and the fish oil groups. Feeding 2% microalgae (Schizochytrium spp.) in hen diet resulted in an increase in the DHA level (above 100 mg/egg) and a decrease in the omega 6:3 ratio to the optimal level. The trial demonstrated that DHA concentration in eggs can be enriched through nutritional management of layers by using algae supplementation in order to provide more favourable fatty acids for consumers.

Dietary supplementation with omega-3 and omega-6 fatty acids offer cardioprotection against air pollution, but these protections have not been established in the brain. We tested whether diets rich in omega-3 or -6 fatty acids offered neuroprotective benefits, by measuring mitochondrial complex enzyme I, II and IV activities and oxidative stress measures in the frontal cortex, cerebellum, hypothalamus, and hippocampus of male rats that were fed either a normal diet, or a diet enriched with fish oil olive oil, or coconut oil followed by exposure to either filtered air or ozone (0.8 ppm) for 4 h/day for 2 days. Results show that mitochondrial complex I enzyme activity was significantly decreased in the cerebellum, hypothalamus and hippocampus by diets. Complex II enzyme activity was significantly lower in frontal cortex and cerebellum of rats maintained on all test diets. Complex IV enzyme activity was significantly lower in the frontal cortex, hypothalamus and hippocampus of animals maintained on fish oil. Ozone exposure decreased complex I and II activity in the cerebellum of rats maintained on the normal diet, an effect blocked by diet treatments. While diet and ozone have no apparent influence on endogenous reactive oxygen species production, they do affect antioxidant levels in the brain. Fish oil was the only diet that ozone exposure did not alter. Microglial morphology and GFAP immunoreactivity were assessed across diet groups; results indicated that fish oil consistently decreased reactive microglia in the hypothalamus and hippocampus. These results indicate that acute ozone exposure alters mitochondrial bioenergetics in brain and co-treatment with omega-6 and omega-3 fatty acids alleviate some adverse effects within the brain.

The research was carried out to assess the possibility of egg yolk enrichment with n-3 PUFA through supplementation of fish oil (FO) and linseed oil (LO) to layer diet. A total of 84 ISA Brown laying hens were divided into three groups. Each group consisted of seven cages with four hens per cage. Groups received diets differing in combinations of oils. The diet fed to group E1 contained 1.50% LO and 3.5% FO, group E2 had diets with 2.5% LO and 2.5% FO, and group E3 was fed diets with 3.5% LO and 1.5% FO. Contents of fatty acids in oils, diets and egg yolks were analyzed. The egg yolk content of α-linolenic acid (α-LNA) and omega-3 polyunsaturated fatty acids (n-3 PUFA) in total fatty acids was increased (P < 0.001) due to the increased content of linseed oil in hen diet and it was the most favourable in group E3. In groups E1, E2 and E3, the α-LNA content was 3.25%, 4.33% and 5.18%, respectively, and the n-3 PUFA content was 6.80%, 7.22% and 8.50%, respectively. The content of eicosapentaenoic acid was higher (P < 0.05) in egg yolks of group E1 than that of groups E2 and E3. No significant differences (P > 0.05) were found among groups in the docosahexaenoic acid content. The omega-6/omega-3 PUFA ratio in groups E1, E2 and E3 was 2.96, 2.93 and 2.49, respectively. Increased concentration of linseed oil and reduced concentration of rapeseed oil in diets resulted in less SFA (P < 0.001) and more n-3 PUFA in egg yolks. It was determined that laying hens have the ability to synthesize EPA and DHA from α-LNA if they receive enough α-LNA through their diets.

Production of omega-3 fatty acids from lemuru fish by-products was studied by enzymatic hydrolysis using a lipase enzyme in one liter of the batch reactor. The hydrolysis temperature of fish oil was set at 45 to 55 ℃ for 0 to 24 h, whereas agitation from 50 to 150 rpm. RSM-Box Bhenken was used to study the effect of these parameters on omega-3 (EPA, docosahexaenoic acid (DHA), and α-linolenic acid (ALA)) content. The % free fatty acid (FFA), acid index, peroxide index, iodine index, and saponification index of lemuru fish oil was 0.925, 2.52, 42.5, 97.28, and 160.11%, respectively. GC-MS analysis results showed that unsaturated fatty acids content (62.34%), which are consisted of omega-3 (EPA, DHA, and ALA), omega-6 and omega-9, was much higher than saturated acids (12.97%). The experiment data showed that the highest EPA (1.221%) and DHA (0.312%) content were reached at 50 ℃ and 24 h with 150 rpm of agitation. However, through the RSM-Box Bhenken analysis and 3D surface plot, it was suggested that the optimum condition was obtained at 45 ℃ and 24 h with 150 rpm of agitation with the content of EPA, DHA, and ALA were 1.709, 0.49, and 1.237%, respectively.
