ABSTRACT

Gas-liquid chromatography analyses have been carried out to investigate the composition of esterified fatty acids in the plasma lipids in 130 Greenland Eskimos, compared with those of 32 Greenland Eskimos living in Denmark and of 31 Caucasian Danes in Denmark. While the Eskimos living in Denmark did not differ substantially from other persons living in Denmark and, from what is found in other studies in Western communities, the Greenland Eskimos showed a completely different pattern. They demonstrated a much higher proportion of palmitic, palmitoleic, and timnodonic acids, while they had a markedly lower concentration of linoleic acid. The total concentration of polyunsaturated fatty acids was lower in Greenland Eskimos than in the other groups. These findings are discussed in the light of the generally accepted opinion of the beneficial effect on plasma lipid levels and on the morbidity of coronary atherosclerosis of a high dietary intake of polyunsaturated fatty acids. As plasma lipid and lipoprotein levels in Greenland Eskimos in a previous study were found markedly lower than those found in Western populations, and as coronary atherosclerosis seems to occur far less commonly among Eskimos in Greenland than among peoples in industrialized countries, it was found difficult to combine these observations with the results from the present study. If dietary differences are the main reason for the differences in plasma lipid concentrations, the results from the present study point more toward qualitative than toward quantitative differences in respect of fatty acid composition of the food.

Omega-3 Fatty Acids
2023, Clinical Lipidology: A Companion to Braunwald's Heart Disease
Omega-3 fatty acids (FAs) are effective therapies for triglyceride reduction, particularly in patients with severe hypertriglyceridemia. Recent data have demonstrated that icosapent ethyl 4 g daily also has profound benefit in cardiovascular risk reduction. This chapter summarizes the nomenclature, lipid-lowering effects, cardiovascular benefits, and mechanisms of omega-3 FAs, with a focus on their clinical utility for hypertriglyceridemia and cardiovascular risk reduction. Future directions for clinical trials are also discussed, with the hope that icosapent ethyl will be only the first of multiple therapeutic options for prevention in this class.
New alternative sources of omega-3 fish oil
2023, Advances in Food and Nutrition Research
Long-chain omega-3 polyunsaturated fatty acids such as eicosapentaenoic and docosahexaenoic acids play an important role in brain growth and development, as well as in the health of the body. These fatty acids are traditionally found in seafood, such as fish, fish oils, and algae. They can also be added to food or consumed through dietary supplements. Due to a lack of supply to meet current demand and the potential for adverse effects from excessive consumption of fish and seafood, new alternatives are being sought to achieve the recommended levels in a safe and sustainable manner. New sources have been studied and new production mechanisms have been developed. These new proposals, as well as the importance of these fatty acids, are discussed in this paper.
Omega-3 and cardiovascular prevention – Is this still a choice?
2022, Pharmacological Research
There is currently growing attention being paid to the role of elevated triglycerides (TGs) as important mediators of residual atherosclerotic cardiovascular disease (ASCVD) risk. This role is supported by genetic studies and by the persistent residual risk of ASCVD, even after intensive statin therapy. Although TG lowering drugs have shown conflicting results when tested in cardiovascular outcome trials, data from the REDUCE-IT study with the ethyl ester of ω-3 eicosapentaenoic acid (EPA) have revived hope in this area of research. The aim of the present review is to critically discuss the most recent large trials with ω-3 fatty acids (FAs) trying to elucidate mechanistic and trial-related differences, as in the case of REDUCE-IT and STRENGTH studies. The ω-3 FAs may lower cardiovascular risk through a number of pleiotropic mechanisms, e.g., by lowering blood pressure, by mediating antithrombotic effects, by providing precursors for the synthesis of specialized proresolving mediators that can inhibit inflammation or by modulating the lipid rafts enriched in cholesterol and sphingolipids. In conclusion, in a field fraught with uncertainties, the ω-3 FAs and especially high dose icosapent ethyl (the ethyl ester of EPA) are at present a most valuable therapeutic option to reduce the ASCVD risk.
The Omega-3 Index is higher in people from a coastal town versus 5 inland US cities: An observational study
2022, Nutrition Research
Higher omega-3 fatty acid blood levels, as assessed by the Omega-3 Index (O3I, erythrocyte eicosapentaenoic [EPA] + docosahexaenoic [DHA] percentage), have been linked with lower risk for cardiovascular disease and total mortality. Because seafood is an excellent source of EPA and DHA, we reasoned that people living on the coast with direct access to fresh seafood might have higher O3I levels than people living inland. Using O3I data originally collected for other purposes and an observational design, we compared the mean O3I from people in Newport, RI, with that of people living from 5 inland US cities (Indianapolis, IN; Charleston, WV; Lexington, KY; Oklahoma City, OK; and Memphis, TN). The Newport samples were collected at free, industry-sponsored health fairs, whereas the inland city samples were collected at free public health screenings sponsored by the Seafood Nutrition Partnership in 2014 through 2015. The mean (standard deviation) O3I in the Newport sample (n = 226) was 5.13% (1.34%) and the mean of the 5 cities (n = 1109) was 4.48% (1.08%) (P < .001). An O3I of ≥8% (considered optimal) was found in 3% of the Newport sample and in 1% of the pooled inland cities (P < .05). An O3I of ≤4% (considered low) was found in 22% of the Newport sample and in 41% of the pooled inland cities (P < .001). These data support our hypothesis, but because only 3% of those in the Newport sample had an O3I >8%, even greater seafood intake (or the use of fortified foods or dietary supplements) is needed to attain optimal omega-3 status.
Microbial production of polyunsaturated fatty acids — high-value ingredients for aquafeed, superfoods, and pharmaceuticals
2021, Current Opinion in Biotechnology
Polyunsaturated fatty acids (PUFAs), primarily docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA), have received worldwide attention in recent years due to an increasing awareness of their uniqueness in improving diet and human health and their apparently inevitable shortage in global availability. Microbial cell factories are a major solution to supplying these precious molecules in sufficient amounts and providing PUFA-rich aquafeed, superfoods, and medical formulations. This review assesses the PUFA world markets and highlights recent advances in upgrading and streamlining microalgae, yeasts, fungi, and bacteria for high-level PUFA production and broadening of the PUFA spectrum.
Polyunsaturated fatty acids synthesized by freshwater fish: A new insight to the roles of elovl2 and elovl5 in vivo
2020, Biochemical and Biophysical Research Communications
At present, fish provide an important supply of long-chain polyunsaturated fatty acids (LC-PUFAs) for human consumption. Previous studies have shown that fatty acyl elongase 2 (elovl2) and elovl5 play important roles in fish LC-PUFA synthesis. Generally, freshwater fish have a stronger ability to synthesize LC-PUFAs than marine fish. However, the roles of elovl2, elovl5 and elovl2 + elovl5 in LC-PUFA synthesis of freshwater fish in vivo are not very clear. In this study, the elovl2 knockout zebrafish (elovl2^−/−), elovl5 knockout zebrafish (elovl5^−/−) and the double gene knockout zebrafish (DKO) were generated by CRISPR/Cas9 technology for the first time. Compared with wild type zebrafish (WT), elovl5-deletion zebrafish showed a significant increase in C22 PUFA content, which might be due to the up-regulation expressions of elovl4b and elovl2. elovl5 expressed at very low levels in livers of elovl2^−/− relative to WT, indicating that elovl5 may be an “assistant attacker” of elovl2 in LC-PUFA synthesis of zebrafish. Moreover, there were no significant differences in levels of C18–C22 PUFAs between DKO and WT, indicating that besides elovl2 + elovl5 path, LC-PUFA synthesis in zebrafish could be performed by other paths. In addition, the hepatic lipidomic analysis results revealed that the contents of C22:6n-3 in phosphatidyl ethanolamine (PE-DHA) and PE-C22 PUFAs were more easily affected by the absence of elovl2 and elovl5. Our results suggest that the elovl2+elovl5 path is not the only path for LC-PUFA synthesis in zebrafish, and provide novel insights into the roles of elovl2 and elovl5 in LC-PUFA synthesis of freshwater fish.
