Under current conditions of life with its intense rhythm, launch of new technologies, lack of time, both physical and mental workloads on a person increase. In these days, doctors more often report patients’ complaints of undue tiredness: they don’t feel rested even after a holiday and/or sleep. Today we tend to detect such manifestations not only in adults. Children also become less stress-resistant, more irritable due to an overabundance of information, and are prone to frequent infections. How can we help the growing generation cope with the increasing workloads? There’s no question, everyone knows about the need to use vitamins, but the right choice is not always possible. There are currently many single-component vitamin supplements and vitamin-mineral complexes. Some people prefer not to use industrially produced vitamins, but those contained in the natural products - fruits, vegetables, berries. But unfortunately, such a diet does not include the group of fat-soluble vitamins - A, D, E, K. In addition, far from everyone understands the importance of eating fatty acids. This article is devoted to the feasibility of additional intake of fat-soluble vitamins, polyunsaturated fatty acids (omega-3), their role in the body and deficiency symptoms. It has been established that the polyunsaturated fatty acid deficiency in the early period of life may trigger the development of cardiovascular disorders, problems associated with high cholesterol content, visual impairment, a drop of immunity, learning difficulties, and nervous system disorders in children in later years. Particular attention is paid to the omega-3 polyunsaturated fatty acid supplement combined with vitamins (A, E, D3), which enhance the positive effects. In addition, it does not cause negative emotions since it has a fruity taste.

Abstract Objectives Cross-sectional studies have found positive associations of plasma omega-3 polyunsaturated fatty acids (N-3 PUFAs) and lung function parameters, including the forced expiratory volume in the first second (FEV1) and forced vital capacity (FVC). We used Mendelian randomization (MR) to address potential limitations in previous findings, including residual confounding and reverse causality, and improve causal inference for the relationship of N-3 PUFAs on lung function. Methods We instrumented the N-3 PUFAs alpha-linolenic acid (ALA), eicosapentanoic acid (EPA), docosahexaenoic acid (DHA) and docosapentaenoic acid (DPA) with genetic variants in the fatty acid desaturase (FADS1/FADS2) and fatty acid elongase (ELOVL2) genes. We performed two sample MR, using genome-wide association data for N-3 PUFAs in the Cohorts for Heart and Aging Research in Genetic Epidemiology Consortium and for FEV1 and FVC in the UK Biobank. We also performed multivariable MR (MVMR) including linoleic acid (LA), the main dietary N-6 PUFA, to account for shared genetic predictors. We used the Wald's ratio or inverse variance weighted method in all analyses. Results In univariable MR, ALA was negatively associated with FEV1 (−0.27 ± 0.13 SD/% total FA, P = 0.02), while EPA was positively associated with FEV1 (0.05 ± 0.02 SD/% total FA, P = 0.02). The DPA—FEV1 association was similar to EPA (P = 0.05). These results align with the opposing effects of FADS1/2 variants on ALA vs EPA and DPA. DHA was not associated with FEV1 and there were no statistically significant N-3 PUFA—FVC associations. Using GWAS estimates adjusted for correlated N3-PUFAs did not alter these results. In MVMR including LA, the ALA—FEV1 associations were strengthened (P = 0.007), while the EPA—and DPA—FEV1 associations were no longer statistically significant. Conclusions Our analyses suggest that higher ALA has a direct negative effect on lung function, while the positive effects of EPA and DPA may be through the balance of N-3 and N-6 PUFA metabolism. However, interpretation of MVRM findings when modeling metabolic pathways needs further consideration.

Prior research studies suggest that maternal polyunsaturated fatty acids could have protective effects on neurodevelopmental outcomes. The objective of this study was to examine associations between maternal polyunsaturated fatty acid intake during pregnancy and risk for autism spectrum disorder and other non-typical development in a prospective cohort. Eligible women already had a child with autism spectrum disorder and were planning a pregnancy or were pregnant with another child. Children were clinically assessed longitudinally and diagnosed at 36 months. Maternal polyunsaturated fatty acid intake during pregnancy was estimated using food frequency questionnaires. Maternal third-trimester plasma polyunsaturated fatty acid concentration was measured by gas chromatography. In all, 258 mother–child pairs were included. Mothers consuming more total omega-3 in the second half of pregnancy were 40% less likely to have children with autism spectrum disorder (relative risk = 0.6, 95% confidence interval: 0.3–0.98). No significant associations were observed between maternal third-trimester plasma polyunsaturated fatty acid subtype concentrations and risk of autism spectrum disorder. However, higher plasma eicosapentaenoic acid and docosahexaenoic acid concentrations were associated with lower non-typical development risk (relative risk ranging from 0.47 to 0.88). This study provides suggestive evidence of associations between risk of autism spectrum disorder in the children and maternal omega-3 intake in late pregnancy but not with third-trimester plasma polyunsaturated fatty acids. Further research is needed to evaluate these potential relationships. Lay abstract Prior studies suggest that maternal polyunsaturated fatty acids intake during pregnancy may have protective effects on autism spectrum disorder in their children. However, they did not examine detailed timing of maternal polyunsaturated fatty acid intake during pregnancy, nor did they evaluate plasma concentrations. This study investigates whether maternal polyunsaturated fatty acids in defined time windows of pregnancy, assessed by both questionnaires and biomarkers, are associated with risk of autism spectrum disorder and other non-typical development in the children. Food frequency questionnaires were used to estimate maternal polyunsaturated fatty acid intake during the first and second half of pregnancy. Gas chromatography measured maternal plasma polyunsaturated fatty acid concentrations in the third trimester. In all, 258 mother–child pairs from a prospective cohort were included. All mothers already had a child with autism spectrum disorder and were planning a pregnancy or pregnant with another child. Children were clinically assessed longitudinally and diagnosed at 36 months. For polyunsaturated fatty acid intake from questionnaires, we only found mothers consuming more omega-3 in the second half of pregnancy were 40% less likely to have children with autism spectrum disorder. For polyunsaturated fatty acid concentrations in the third-trimester plasma, we did not observe any statistical significance in relation to the risk of autism spectrum disorder. However, our study confirmed associations from previous studies between higher maternal docosahexaenoic acid and eicosapentaenoic acid plasma concentrations in the late pregnancy and reduced risk for non-typical development. This study markedly advanced understandings of whether and when maternal polyunsaturated fatty acid intake influences risk for autism spectrum disorder and sets the stage for prevention at the behavioral and educational level.

Acute respiratory distress syndrome (ARDS) is defined as the acute onset of noncardiogenic edema and subsequent gas-exchange impairment due to a severe inflammatory process. Recent report on the prognostic value of eicosanoids in patients with ARDS suggests that modulating the inflammatory response through the use of polyunsaturated fatty acids may be a useful strategy for ARDS treatment. The use of enteral diets enriched with eicosapentaenoic acid (EPA) and gamma-linolenic acid (GLA) has reported promising results, showing an improvement in respiratory variables and haemodynamics. However, the interpretation of the studies is limited by their heterogeneity and methodology and the effect ofω-3 fatty acid-enriched lipid emulsion or enteral diets on patients with ARDS remains unclear. Therefore, the routine use ofω-3 fatty acid-enriched nutrition cannot be recommended and further large, homogeneous, and high-quality clinical trials need to be conducted to clarify the effectiveness ofω-3 polyunsaturated fatty acids.

Background: Supplementation of fat, especially those having unsaturated fatty acids has been proposed to carry positive effects on the reproductive organ, beside providing dietary energy to the animals. This experiment was designed to examine the effects of dietary ω-3 or ω-6 fatty acid (FA) rich oil supplementation on blood FA, metabolite and hormone concentrations; ovarian follicular growth and corpus luteum (CL) size in Sahiwal breed heifers.Methods: Eighteen heifers of 18.33±1.14 months of age and 194±4.16 kg of mean body weight were randomly assigned to 3 diets and individually fed as per ICAR (2013) diets. The diets include chopped wheat straw, green fodder and concentrate mixture containing either (i) no added PUFA rich oil but palm oil @ 3.5% (PO; n=6); (ii) 3.5% added soybean oil as ω-6 FA source (SO; n=6); or (iii) 3.5% added linseed oil as ω-3 FA source (LO; n=6).Result: SO increased (P less than 0.05) the plasma concentration of ω-6 FA while LO increased (P less than 0.05) the plasma ω-3 FA. Plasma glucose, triglyceride and non-esterified fatty acid (NEFA) concentrations was not affected due to different diets. Plasma total cholesterol and HDL-cholesterol were significantly higher (P less than 0.05) in SO and LO in comparison to PO. However, LDL-cholesterol was at par among all the treatments. Growth Hormone (GH) was not influenced due to different types of oil in heifers’ concentrate mixture. Insulin concentration increased (P less than 0.05) in LO compared to others. IGF-1 was statistically higher (P less than 0.05) in SO and LO as compared to CON, which among themselves also varied significantly. Plasma progesterone concentration at day 12 post estrous was higher (P less than 0.05) in LO. PUFA rich oil supplementation in the concentrate mixture of heifers (SO and LO) increased (P less than 0.05) the size of the ovulatory follicles as well as size of CL. It was inferred that feeding PUFA rich oil to pre-pubertal Sahiwal heifer’s results in advantageous changes in the blood metabolites, plasma hormones and ovarian functions.

The fatty acid compositions of the fish muscle and liver are substantially affected by rearing environment. However, the mechanisms underlying this effect have not been thoroughly described. In this study, we investigated the effects of different culture patterns, i.e., marine cage culture and freshwater pond culture, on long-chain polyunsaturated fatty acids (LC-PUFA) biosynthesis in an aquaculturally important fish, the Japanese sea bass (Lateolabrax japonicus). Fish were obtained from two commercial farms in the Guangdong province, one of which raises Japanese sea bass in freshwater, while the other cultures sea bass in marine cages. Fish were fed the same commercial diet. We found that omega-3 long-chain polyunsaturated fatty acids (n-3 LC-PUFA) levels in the livers and muscles of the marine cage cultured fish were significantly higher than those in the livers and muscles of the freshwater pond cultured fish. Quantitative real-time PCRs indicated that fatty acid desaturase 2 (FADS2) transcript abundance was significantly lower in the livers of the marine cage reared fish as compared to the freshwater pond reared fish, but that fatty acid elongase 5 (Elovl5) transcript abundance was significantly higher. Consistent with this, two of the 28 CpG loci in the FADS2 promoter region were heavily methylated in the marine cage cultured fish, but were only slightly methylated in freshwater pond cultured fish (n = 5 per group). Although the Elovl5 promoter was less methylated in the marine cage reared fish as compared to the freshwater pond reared fish, this difference was not significant. Thus, our results might indicate that Elovl5, not FADS2, plays an important role in the enhancing LC-PUFA synthesis in marine cage cultures.

There are four types of fatty acids but only two types are essential nutritional requirements for many animals. These are the omega-6 polyunsaturated fatty acids (n-6 PUFA) and the omega-3 polyunsaturated fatty acids (n-3 PUFA) and because they cannot be converted to one another they are separate essential dietary requirements. They are only required in small amounts in the diet and their biological importance stems largely from their role as constituents of membrane lipids. They are synthesised by plants and, as a generalisation, green leaves are the source of n-3 PUFA while seeds are the source of n-6 PUFA in the food chain. While the fatty acid composition of storage fats (triglycerides) is strongly influenced by dietary fatty acid composition, this is not the case for membrane fats. The fatty acid composition of membrane lipids is relatively unresponsive to dietary fatty acid composition, although n-3 PUFA and n-6 PUFA can substitute for each in membrane lipids to some extent. Membrane fatty acid composition appears to be regulated and specific for different species. The role of essential fats in the diet of animals on (1) basal metabolic rate, (2) thermoregulation, (3) maximum longevity, and (4) exercise performance is discussed.
