Crop Variety

SAU Perilla-1 (Golden perilla BD) is a newly edible oil seed crop variety introduced by Sher-e-Bangla Agricultural University in Bangladesh. Its seed oil is a rich source of unsaturated fatty acid (91%), of which more than 50% is α-linolenic acid (type of omega-3 fatty acid). The estimated ratio of saturated, monounsaturated and polyunsaturated fatty acids was found 1: 2.26: 8.95. Moreover, the α-linolenic acid was detected (50.52%) as the most dominating polyunsaturated fatty acid, which was 4-four times higher than monounsaturated fatty acids in the oil of the crop variety. Fatty acid analysis of oil revealed a ratio (1:2.22) of Omega 6 to Omega 3 fatty acids, which lies within a healthy range as documented by the global scientific community. Compared to other plant seed oils, SAU Perilla-1 oil consists of Linoleic acid (Omega 6 fatty acid, 22.71%) – a component associated with obesity, which is far below the regular oils from soybean, sunflower and corn. Therefore, our findings indicated that SAU Perilla-1 seed is one of the best edible sources of plant oils rich in essential fatty acids conducive to human health.

The article analyzes the fatty acid composition of the frozen iwashi lipids of different shelf lives. It is established that the total amount of essential fatty acids omega-3 and omega-6 in iwashi’s fat reaches almost 90% of all polyunsaturated fatty acids and remains practically unchanged for 12 months of fish cold storage. It is shown that products from iwashi contain a significant amount of essential fatty acids, indispensable for the human body, which can be used to optimize the population nutrition and satisfy the physiological needs in eicosopentaenoic and docosahexaenoic fatty acids.

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.

AbstractA twelve-month study was conducted on changes in fatty acid composition and pesticide residues in honeybees and beebread. In honeybees, saturated fatty acid and monounsaturated fatty acid gradually increased as summer began then decreased when spring started, and polyunsaturated fatty acid had an opposite seasonal trend. Similar fluctuation was observed in the beebread collected from the same hive as those honeybees through summer to fall, especially in the essential fatty acids omega-6 and omega-3. Honeybees’ lipid metabolism can be disrupted after being exposed to a sub-lethal level of pesticide. Although three out of sixteen analyzed pesticides were detected in beebread samples summer through fall in our study, we were not able to find any negative affect of those pesticides on the honeybees’ fatty acid composition. Temporary field-realistic pesticide exposure may weaken honeybees but are unlikely to show any reflection in their fat bodies if the colony was otherwise healthy.

Prevalence Of Obesity ◽  
Underlying Diseases

Every year around the world, the prevalence of obesity is increasing. Obesity and its associated diseases have become some of the most pressing health problems in developed and developing countries. In its development, adipocytes dysfunction and chronic low-grade inflammation occur in obesity will stimulate diseases at higher risk including type 2 diabetes mellitus (T2DM), atherosclerosis, hypertension, and metabolic syndrome. Western diet and sedentary lifestyle are thought to have significantly contributed to the increase in obesity recently. Diet modification is a sound method to prevent obesity and its complications. Nevertheless, the concern lies in the ratio of omega-6 towards omega-3 fatty acids intake, which in its current state indicates an imparity. Omega-3 and omega-6 are two essential fatty acids that emerge as dominant factors in obesity through adiponectin. Adiponectin refers to a protein hormone conceived by adipocytes to prevent obesity and its subsequent complications by increasing insulin sensitivity, fatty acid oxidation, anti-inflammatory, and antiaterogenic. This study aims to determine the mechanism and the role of fatty acids in omega-6 towards those within omega-3 by using adiponectin as the indicator of advancement to obesity and its underlying diseases.

Macro And Micronutrients

In the recent decades, peoples concentrate more on reduced-consumption of diets containing saturated fatty acids and replace them with essential polyunsaturated ones, including omega-3 and omega-6 fatty acids, due to their promising nutritional benefits. Therefore, the production of chicken meat having lower fat compositions, and riches in pro-healthy fatty acid and other macro-and micronutrients deserves great attention in the food industry. The research aimed to characterize meat oils of two commercially available, domestic and poultry, chickens in the Northern part of Bangladesh (Rajshahi), followed by the investigation of their nutritional compositions and hypoglycemic effect in vivo. In this work, the oil was isolated from the dried meat sources by Soxhlet extractor and purified using a rotary evaporator. We subsequently characterized meat oil in terms of various parameters, such as iodine value, saponification number, unsaponifiable matter, free fatty acid (FFA) contents, peroxide value, and acid value. Besides, the nutritional parameters of chicken oil were investigated as percentages of essential fatty acids and several other micro-and macronutrients using gas-liquid chromatography and other conventional methods. Finally, Alloxan-induced Wister rats were fed with oil and chicken flesh to investigate the hypoglycemic effects. The experimental analyses show that chicken oil possesses a significant proportion of omega-3 and omega-6 fatty acid, macro-and micronutrients. Besides, oil and flesh were found to lower blood glucose levels in diabetic rats despite flesh could not significantly show hypoglycemic properties.

Synthesis And Degradation

The ability of derivatives of the essential fatty acids linoleic acid (C18:2, omega 6) and alpha-linolenic acid (C18:3, omega 3) to stimulate rates of protein synthesis and degradation was investigated in isolated intact muscles from fasted rabbits. Both omega 6 derivatives examined, arachidonic acid (C20:4, omega 6) and dihomo-gamma-linolenic acid (C20:3, omega 6), when added at concentrations up to 1 microM, stimulated the rate of protein synthesis and the release of prostaglandin F2 alpha (PGF2 alpha). Metabolites of the omega 6 series, namely eicosapentaenoic acid (C20:5, omega 3) and docosahexaenoic acid (C22:6, omega 3), were without effect on the rate of protein synthesis and resulted in a decrease in the release of PGF2 alpha. None of the fatty acids had a significant effect on the rate of protein degradation. Although insulin (100 mu units/ml) also stimulated rates of protein synthesis when added alone, none of the omega 3 or omega 6 fatty acids, when added with insulin at concentrations of 0.2 microM, potentiated the effect of the hormone.

ABSTRACT STUDY QUESTION Are serum omega-3 and omega-6 essential fatty acid concentrations associated with the probability of conceiving? SUMMARY ANSWER There is no strong association between serum concentrations of omega-3 and omega-6 fatty acids and the probability of conceiving naturally. WHAT IS KNOWN ALREADY Omega-3 and omega-6 fatty acid serum concentrations have been shown to play an important role in reproduction in animal models, while conflicting results have been reported in human studies of infertile women. It is unknown to what extent omega fatty acid serum concentrations impact natural fertility. STUDY DESIGN, SIZE, DURATION A nested, case–control study was conducted consisting of 200 participants [fertile: conceived within 3 cycles of attempt (n = 50), subfertile: conceived within 4 and 12 cycles of attempt (n = 100) and infertile: did not conceive within 12 cycles of attempt (n = 50)] randomly selected from the Time to Conceive cohort, a prospective time-to-pregnancy study (2008 to 2015). PARTICIPANTS/MATERIALS, SETTING, METHODS In the Time to Conceive study, women aged 30–44 years who were trying to conceive for <3 months and had no history of infertility were recruited and followed until the end of their pregnancy or ~1 year of pregnancy attempt. For this study, serum collected early in the woman’s pregnancy attempt was analysed for anti-Müllerian hormone (AMH) and omega-3 and omega-6 fatty acid concentrations by liquid chromatography-mass spectrometry. The primary outcome was a positive home pregnancy test. The secondary outcomes were miscarriage and serum AMH level. A discrete-time Cox proportional hazards model was used to estimate the fecundability ratio. The odds ratios for miscarriage were calculated using logistic regression. The association between serum omega fatty acid concentrations and AMH level (natural log transformed) was analysed using Pearson’s Correlation. MAIN RESULTS AND THE ROLE OF CHANCE A total of 200 women provided 1321 cycles for analysis. Mean omega-3, omega-6 and omega-6:omega-3 ratios did not significantly differ between the fertile, subfertile and infertile groups. There were no associations (all fecundability ratios ~1.0) between pregnancy and individual omega-3 fatty acid concentrations, including alpha-linolenic acid, eicosapentaenoic acid and docosahexaenoic acid, or omega-6 fatty acids, including linoleic acid (LA), dihommo-gamma linolenic acid and arachidonic acid. There was no significant association between any individual omega fatty acid serum concentration and the age-adjusted odds of miscarriage. No association was found between any serum omega fatty acid concentration and AMH. LIMITATIONS, REASONS FOR CAUTION This study is limited by the sample size. Omega-3 and omega-6 fatty acid concentrations were derived from serum provided at a single timepoint in the first cycle of enrollment. Serum concentrations may therefore not be representative of all critical timepoints in the menstrual cycle or throughout their attempts to conceive. Additionally, women enrolled in this study were 30 years of age and older, and therefore the findings may not apply to younger women. WIDER IMPLICATIONS OF THE FINDINGS These data would suggest that omega-3 and omega-6 serum levels are not associated with natural fertility or risk of miscarriage. However, due to the above-mentioned limitations, future investigation is still needed to determine whether omega-3 fatty acid supplementation may benefit women planning to conceive naturally. STUDY FUNDING/COMPETING INTEREST(S) This study was supported by the Division of Reproductive Endocrinology and Infertility at the University of North Carolina at Chapel Hill, by the NIH/NICHD (R21 HD060229-01 and R01 HD067683-01) and, in part, by the Intramural Research Program of the National Institute of Environmental Health Sciences (Z01ES103333).

Context. Several studies have shown a link between proinflammatory activity and the presence or deficit of some fatty acids. Inflammation is associated with several diseases including diabetes.Objective. To characterize and compare the fatty acids profiles in children with inaugural type 1 diabetes, diabetic children (at least 1 year after diagnosis), and healthy children.Design. Plasma fatty acids profiles in children with inaugural diabetes, children with noninaugural diabetes, and controls, all of whom were prepubescent with a BMI < 85th percentile, were evaluated.Results. Omega-3 fatty acid levels were higher in recently diagnosed subjects with diabetes than in controls. The ratio of omega-6/omega-3 fatty acids was higher in the control population. Omega-6 fatty acid levels were higher in the nonrecent diabetic subjects than in the children with recently diagnosed diabetes, and the levels were higher in the nonrecent diabetes group compared to the control group.Conclusion. Our findings showed higher levels of alpha-linolenic acid, EPA, and DHA, as well as mono- and polyunsaturated fatty acids, in diabetic children. These findings reinforce the importance of precocious nutritional attention and intervention in the treatment of diabetic children.
