The Impact

Numerous United Kingdom and European Union expert panels recommend that the general adult population consumes ~250 mg of eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) per day through the consumption of one portion of oily fish per week. The long-chain omega-3 fatty acids EPA and DHA are only found in appreciable amounts in marine organisms. Increasing oily fish consumption conflicts with sustaining fisheries, so alternative dietary sources of EPA and DHA must be explored. Mussels are high in omega-3 polyunsaturated fatty acids (PUFAs) and a good source of essential amino acids. Therefore, we aimed to investigate the impact of introducing mussels as a protein source in the lunchtime meal three times per week for two weeks on the omega-3 status of free-living participants. Following an initial two-week monitoring period, 12 participants (eight male and four female) attended the nutrition laboratory three times per week for two weeks. Each participant received a personalised lunch constituting one-third of their typical daily calorie consumption with ~20% of the calories supplied as cooked mussels. A portion of cooked mussels from each feeding occasion was tested for total omega-3 content. The mean ± SD mussel EPA + DHA content was 518.9 ± 155.7 mg/100 g cooked weight, meaning that each participant received on average 709.2 ± 252.6 mg of EPA + DHA per meal or 304.0 ± 108.2 mg of EPA + DHA per day. Blood spot analysis revealed a significant increase in the omega-3 index (week 1 = 4.27 ± 0.81; week 4 = 5.07 ± 1.00) and whole blood EPA content during the study (%EPA week 1 = 0.70 ± 0.0.35; %EPA week 4 = 0.98 ± 0.35). Consuming mussels three times per week for two weeks as the protein source in a personalised lunchtime meal is sufficient to moderately improve the omega-3 index and whole blood DHA + EPA content in young healthy adults.

The Impact

From a global health perspective, increased intake of omega-3 fatty acids (FAs), in particular eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), are beneficial for human health. However, the consumption of EPA- and DHA-rich foods such as fatty fish is low in the Western diet. Therefore, finding new ways to motivate people to increase their consumption of omega-3 FAs is essential. To find effective ways to motivate individuals, understanding people’s awareness of omega-3 FAs and how they obtain their knowledge about nutrition and health is critical. Consequently, we developed an online survey to assess awareness and self-reported intake of omega-3 FAs and supplements in young adults. EPA and DHA are also produced endogenously to a limited extent through a pathway regulated by fatty acid desaturase 1 and 2 (FADS1 and FADS2) genes. Of relevance, single nucleotide polymorphisms (SNPs) in the FADS genes influence levels of omega-3 FAs, where minor allele carriers have lower levels compared with major allele carriers. Accordingly, we conducted a clinical trial to investigate FA levels in response to dietary EPA and DHA supplementation in young adults stratified by SNPs in FADS1 and FADS2. The level of reported awareness of omega-3 terminology varied depending on an individual’s field of study and thus providing all participants with the same set of nutrition information could be an effective tool to increase knowledge and motivate behaviour change. Additionally, the variation in FA levels in accordance to SNPs in FADS1 and FADS2 could be used to create tailored nutritional recommendations which may improve lifestyle habits. The results discovered in the first 2 studies regarding awareness of omega-3 FAs and genetic variation were subsequently used to design a nutrigenetics intervention in young adults. Individuals who received their FADS1 genetic information were more aware of different omega-3 FAs and reported fewer barriers to their consumption by the end of the study, compared with those who did not receive their personal genetic information. All participants increased their intake of EPA and DHA, which was reflected in the analyses of red blood cells. Overall, this thesis demonstrates the power of combining nutritional and genetic information as motivators to increase omega-3 consumption.

Different Tissues

Omega-3 long-chain polyunsaturated fatty acids (n-3 LC-PUFA), such as eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) play an important role in human health. Fish oils enriched with EPA and DHA have commercialized in triacylglycerol (TAG) and ethyl ester forms (EE). In this study, we compared the impact of diets containing fish oil in ethyl ester and triacylglycerol forms as a lipid source in five different tissues as liver, skeleteral muscle, brain, and epididymal white adipose tissue (WAT). The DHA levels were higher in the WAT and skeletal muscle of TAG and EE groups in comparison with the SB group. The body weight and brain, liver, epididymal WAT, and gastrocnemius muscle weights, and serum glucose, TG, cholesterol were not different between the groups. Thus, we conclude that EPA and DHA in the form of EE or TAG influence the fatty acids composition of different tissues.

The sensitivity of fingertip whole blood to reflect habitual dietary and dose-dependent supplemental omega-3 long-chain polyunsaturated fatty acid (n-3 LCPUFA) intake in premenopausal women was compared to that of venous erythrocytes and plasma fatty acids. Samples were obtained from women in a randomised, double-blind, placebo-controlled trial in which premenopausal women (n = 53) were supplemented with DHA-rich tuna oil capsules and/or placebo (Sunola oil) capsules (6 capsules per day) for 8 weeks to achieve doses of either 0, 0.35, 0.7 or 1.05 g/day n-3 LCPUFA. All blood biomarkers were very similar in their ability to reflect dietary n-3 LCPUFA intake (r = 0.38–0.46 for EPA and DHA intake), and in their dose-dependent increases in n-3 LCPUFA levels after supplementation (R2 = 0.41–0.51 for dose effect on biomarker EPA and DHA levels (mol %)). Fingertip whole blood is an effective alternative to erythrocytes and plasma as a biomarker n-3 LCPUFA intake in premenopausal women.

The nutrient composition of 15 commercially available microalgae powders of Arthrospira platensis, Chlorella pyrenoidosa and vulgaris, Dunaliella salina, Haematococcus pluvialis, Tetraselmis chuii, and Aphanizomenon flos-aquae was analyzed. The Dunaliella salina powders were characterized by a high content of carbohydrates, saturated fatty acids (SFAs), omega-6-polyunsaturated fatty acids (n6-PUFAs), heavy metals, and α-tocopherol, whereas the protein amounts, essential amino acids (EAAs), omega-3-PUFAs (n3-PUFAs), vitamins, and minerals were low. In the powder of Haematococcus pluvialis, ten times higher amounts of carotenoids compared to all other analyzed powders were determined, yet it was low in vitamins D and E, protein, and EAAs, and the n6/n3-PUFAs ratio was comparably high. Vitamin B12, quantified as cobalamin, was below 0.02 mg/100 g dry weight (d.w.) in all studied powders. Based on our analysis, microalgae such as Aphanizomenon and Chlorella may contribute to an adequate intake of critical nutrients such as protein with a high content of EAAs, dietary fibers, n3-PUFAs, Ca, Fe, Mg, and Zn, as well as vitamin D and E. Yet, the nutritional value of Aphanizomenon flos-aquae was slightly decreased by high contents of SFAs. The present data show that microalgae are rich in valuable nutrients, but the macro- and micronutrient profiles differ strongly between and within species.

The Impact

Milk contains several important nutrients that are beneficial for human health. This review considers the nutritional qualities of essential fatty acids (FAs), especially omega-3 (ω-3) and omega-6 (ω-6) polyunsaturated fatty acids (PUFAs) present in milk from ruminant and non-ruminant species. In particular, the impact of milk fatty acids on metabolism is discussed, including its effects on the central nervous system. In addition, we presented data indicating how animal feeding—the main way to modify milk fat composition—may have a potential impact on human health, and how rearing and feeding systems strongly affect milk quality within the same animal species. Finally, we have presented the results of in vivo studies aimed at supporting the beneficial effects of milk FA intake in animal models, and the factors limiting their transferability to humans were discussed.

AbstractBackgroundThe objective of the study was to compare the effect of eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) dietary supplementation on their concentration in total lipids (TL) and lipid fractions of maternal and umbilical vein (UV) blood. The specific objective was to analyze the impact of EPA and DHA supplementation on pregnancy outcome and neonatal birth weight.MethodsWomen were randomly single-blinded (randomized controlled trial; ISRCTN36705743) allocated to the group receiving EPA and DHA supplementation (supplemented group) or the group receiving placebo-corn oil (control group) in the time period from January 1st, 2016 until March 1st, 2017. Women in the supplemented group (n=45) took 360 mg EPA and 240 mg DHA daily while controls (n=42) were given a placebo. Maternal and UV bloods were obtained at delivery. After lipid extraction, phospholipids (PL), cholesterol esters (CE), triacylglycerols (TG) and non-esterified fatty acids were separated by thin layer chromatography and analyzed by gas chromatography.ResultsHigher DHA concentrations in TL (37.24±21.87 mg/L), PL (13.14±8.07 mg/L) and triacylglycerols (2.24±2.21 mg/L) were recorded in mothers from the supplemented group when compared to the study group (TL 21.89±14.53 mg/L; P<0.001; PL 9.33±5.70 mg/L; P=0.013; TG 0.56±0.43 mg/L; P<0.001). Higher DHA concentrations in UV samples were found in TL (11.51±7.34 mg/L), PL (5.29±3.31 mg/L) and triacylglycerols (0.62±0.46 mg/L) from the supplemented groups compared with controls (TL 7.37±3.60 mg/L; P=0.002; PL 3.52±2.19 mg/L; P=0.005; TG 0.40±0.46 mg/L; P=0.035). The ratio of AA:DHA was lower in maternal (2.43) and UV serum (4.0) of the supplemented group than in the control group (maternal 3.85 P<0.001; UV 4.91 P<0.001).ConclusionThe study demonstrated the higher ratio of AA/DHA in the control group indicating that pregnant women on the traditional Herzegovina diet need supplementation with DHA and EPA.

The Impact

Viral infections are a leading cause of morbidity and mortality worldwide, and the importance of public health practices including handwashing and vaccinations in reducing their spread is well established. Furthermore, it is well known that proper nutrition can help support optimal immune function, reducing the impact of infections. Several vitamins and trace elements play an important role in supporting the cells of the immune system, thus increasing the resistance to infections. Other nutrients, such as omega-3 fatty acids, help sustain optimal function of the immune system. The main aim of this manuscript is to discuss of the potential role of micronutrients supplementation in supporting immunity, particularly against respiratory virus infections. Literature analysis showed that in vitro and observational studies, and clinical trials, highlight the important role of vitamins A, C, and D, omega-3 fatty acids, and zinc in modulating the immune response. Supplementation with vitamins, omega 3 fatty acids and zinc appears to be a safe and low-cost way to support optimal function of the immune system, with the potential to reduce the risk and consequences of infection, including viral respiratory infections. Supplementation should be in addition to a healthy diet and fall within recommended upper safety limits set by scientific expert bodies. Therefore, implementing an optimal nutrition, with micronutrients and omega-3 fatty acids supplementation, might be a cost-effective, underestimated strategy to help reduce the burden of infectious diseases worldwide, including coronavirus disease 2019 (COVID-19).

Pampus Argenteus

Marine fish are well-known for being a high-quality protein source having high concentration of essential amino acids. It has high concentration of mono unsaturated and poly unsaturated fatty acids, which may aid in the optimization of lipid profiles and the reduction of the risk of coronary heart disease (CHD). The goal of this study was to estimate the nutritional and biochemical status of raw sea fish Pampus argenteus after 30 days of frozen storage at -200C with 15-day intervals. Nutrient study showed a decrease in protein and lipid content. The changes of hydrogen peroxide and oxidized lipid products were estimated in the muscle tissue during fresh and storage condition. Results indicate that during storage the oxidative stress increased. An antioxidant enzyme (superoxide dismutase, smutase, catalase, glutathione peroxidase) measurement was determined. The increased amount of oxidative stress during fish storage is shown by the differential activity of antioxidant enzymes. The amount of protein in fish varies slightly between species and even within species. Fish is high in protein, vitamins, minerals, and omega-3 fatty acids, which are essential for brain development (Spencer et al., 1971; Jacylin et al., 2010). A well-balanced diet consists variety of fish that can help in children's growth and development as well as their heart health (Jinadasa, 2014).
