Widespread use of antimicrobial drugs has led to high levels of drug-resistance in pathogen populations and a need for novel sources of anti-bacterial and anti-parasitic compounds. Macroalgae (seaweed) are potentially a rich source of bioactive compounds, and several species have traditionally been used as vermifuges. Here, we investigated the anti-parasitic properties of four common cold-water Nordic seaweeds; Palmaria palmata (Rhodophyta), Laminaria digitata, Saccharina latissima and Ascophyllum nodosum (Ochrophyta, Phaeophyceae). Screening of organic extracts against helminths of swine (Ascaris suum) and sheep (Teladorsagia circumcincta) revealed that S. latissima and L. digitata had particularly high biological activity. A combination of molecular networking and bio-guided fractionation led to the isolation of six compounds from extracts of these two species identified in both fermented and non-fermented samples. The six isolated compounds were tentatively identified by using MS-FINDER as five fatty acids and one monoglyceride: Stearidonic acid (1), Eicosapentaenoic acid (2), Alpha-Linolenic acid (3), Docosahexaenoic acid (4), Arachidonic acid (5), and Monoacylglycerol (MG 20:5) (6). Individual compounds showed only modest activity against A. suum, but a clear synergistic effect was apparent when selected compounds were tested in combination. Collectively, our data reveal that fatty acids may have a previously unappreciated role as natural anti-parasitic compounds, which suggests that seaweed products may represent a viable option for control of intestinal helminth infections.

AbstractThe fatty acid profiles of the three lipid fractions, neutral lipids (NL), free fatty acids and polar lipids (PL), from the macroalgae Palmaria palmata (wild), Alaria esculenta (cultivated) and Saccharina latissima (cultivated) were studied in light of dietary important fatty acids. Blade and stipe from the macroalgae were collected at the end of the growth season (May/June) at Frøya (Trøndelag, Norway). A total of 51 fatty acids were identified in the algae, including several fatty acids novel to one or more of the algae. The NL and PL fractions of P. palmata were the most promising from a health perspective, due to a high content of eicosapentaenoic acid (10.1 ± 0.5% and 6.6 ± 0.1%, respectively) and no trans-fatty acids. In addition, these fractions had very low omega-6/omega-3 ratios (< 0.1) and can therefore be beneficial for balancing the omega-6/omega-3 ratio in the diet. The NL fraction of A. esculenta had the highest content of monounsaturated- and polyunsaturated fatty acids (20.9 ± 1.4 and 21.8 ± 1.9% of alga, respectively), as well as the highest content of the two essential fatty acids, linoleic acid (5.3 ± 0.4% of alga) and alpha-linolenic acid (2.4 ± 0.2% of alga). Indices related to risk factors for coronary heart disease were most favourable in the NL fraction of S. latissima and the NL and PL fractions of A. esculenta.

Good sources of the long-chain n-3 fatty acids, eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) include cold-water fish and seafood; however, vegan diets (VGNs) do not include animal-origin foods. Typically, US omnivores obtain enough dietary EPA and DHA, but unless VGNs consume algal n-3 supplements, they rely on endogenous production of long-chain fatty acids. VGN diets have several possible concerns: (1) VGNs have high intakes of linoleic acid (LA) as compared to omnivore/non-vegetarian diets. (2) High intakes of LA competitively interfere with the endogenous conversion of alpha-linolenic acid (ALA) to EPA and DHA. (3) High somatic levels of LA/low ALA indicate a decreased ALA conversion to EPA and DHA. (4) Some, not all VGNs meet the Dietary Reference Intake Adequate Intake (DRI-AI) for dietary ALA and (5) VGN diets are high in fiber, which possibly interferes with fat absorption. Consequently, health professionals and Registered Dietitians/Registered Dietitian Nutritionists working with VGNs need specific essential fatty acid diet guidelines. The purpose of this review was: (1) to suggest that VGNs have a DRI-AI Special Consideration requirement for ALA and LA based on VGN dietary and biochemical indicators of status and (2) to provide suggestions to ensure that VGNs receive adequate intakes of LA and ALA.

Changes in the composition of fatty acids (FA) were determined in lipid extracts isolated from developing ovaries containing ovules and developing seeds of Echium vulgare L. The samples were collected successively over 20 days beginning with the first day after flowering. The contents of the n-6 FA family members, i.e., gamma-linolenic (GLA) (C(18:3)) and linoleic (LA) (C(18:2)) acids changed in a parallel manner and reached the maximum of 13.9% and 24%, respectively, on the 12th day, after which they fell systematically down to 8.6% and 18.2%, respectively, on the 20th day after flowering. Starting with day 13, the content of alpha-linolenic acid (ALA) (C(18:3) n-3) begins to grow intensively, from 24.2% to 39.3% on the 20th day after flowering. The increase in the content of stearidonic acid (SDA) (C(18:4) n-3), up to 10.5% on the 20th day after flowering, occurred steadily as the seeds developed, and was independent of the changes in the content of GLA and LA. The pattern of changes in the content of SDA, GLA, LA and ALA during the development of seeds, and the occurrence of SDA in the seed oil of other plants, demonstrate that the biosynthesis of SDA in the seeds is critically dependent on the presence of ALA. The above condition indicates that SDA biosynthesis in the seeds of Echium vulgare follows the scheme LA --> simultaneous, competitive, action of Delta(6) and Delta(15) desaturases, leading to the formation of GLA and ALA, respectively, and then ALA (Delta(6) des) --> SDA. The biosynthesis according to the scheme: GLA (Delta(15) des) --> SDA is highly unlikely.

Abstract Breast milk is considered a complete food and the immediate effects of breastfeeding on the babies’neurological development are already recognized. This study aimed to describe the importance of continued breastfeeding and the influence of fatty acids on the infant's neurological maturation. For the study development, a systematic review was adopted, in which online search bases such as SciELO, PubMed and Google Scholar were used and whose publications comprised the period from 2008 to 2021. Out of the 969 articles found, 47 of them were selected that fulfilled the objective of the study. Breast milk is essential for the child's development and the benefits extend into adulthood, such as less chance of developing obesity, cardiovascular diseases, diabetes, hypersensitivity reactions, respiratory and gastrointestinal diseases. The mother-child bond is strengthened, enabling the child to develop emotionally, in addition to reducing the incidence of cancer in the mother. Breast milk has essential fatty acids (AGEs), such as linoleic and alpha-linolenic acid , which are essential for the development of neurological, visual and cellular activities. These compounds are present in breast milk in greater proportion than other types of milk and the more the mother ingests foods such as deep and cold water fish, seeds, flaxseed, chia, the greater the presence of AGEs and more benefits for the embryo-fetal period and for the infant. Thus, encouraging the breast milk consumption through suction improves stomatognathic functions, promoting harmonious orofacial growth, muscle balance, breathing coordination and proper tongue posture.

Resumo O leite materno é considerado um alimento completo e os efeitos imediatos da amamentação no desenvolvimento neurológico dos bebês já é reconhecido. Esse estudo teve como objetivo descrever a importância da amamentação continuada e a influência dos ácidos graxos na maturação neurológica do lactente. Para o desenvolvimento do estudo, adotou-se uma revisão sistemática, no qual foram utilizadas as bases de busca on line como SciELO, PubMed e Google Acadêmico e cujas publicações compreenderam o período entre de 2008 a 2021. Dos 969 artigos encontrados, foram selecionados 48 que atenderam ao objetivo do estudo. O leite materno é fundamental para o desenvolvimento da criança e os benefícios se estendem até a vida adulta, tais como menor chances de desenvolver obesidade, doenças cardiovasculares, diabetes, reações de hipersensibilidade, doenças respiratórias e gastrintestinais. O vínculo mãe-filho fica fortalecido, dando condições à criança de se desenvolver emocionalmente, além de diminuir a incidência de câncer na mãe. O leite materno possui ácidos graxos essenciais (AGE), como linoleico e linolênico, que são fundamentais para o desenvolvimento das atividades neurológicas, visuais e celulares. Esses compostos estão presentes no leite materno em maior proporção que outros tipos de leite e quanto mais a mãe ingerir alimentos como peixes de águas profundas e frias, sementes, linhaça, chia, maior será a presença dos AGE e mais benefícios para o período embriofetal e para o lactente. Desta forma incentivar o consumo de leite materno de forma prolongada, pela sucção melhora as funções estomatognáticas, promovendo crescimento orofacial harmonioso, equilíbrio da musculatura, coordenação da respiração e postura adequada de língua.

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.

Background. Omega-3 (n-3) and omega-6 (n-6) polyunsaturated fatty acids (PUFAs) may have different effects on cognitive health due to their anti- or pro-inflammatory properties. Methods. We aimed to prospectively examine the relationships between n-3 and n-6 PUFA contents in serum phospholipids with incident all-cause dementia and Alzheimer’s disease dementia (AD). We included 1264 non-demented participants aged 84 ± 3 years from the German Study on Ageing, Cognition, and Dementia in Primary Care Patients (AgeCoDe) multicenter-cohort study. We investigated whether fatty acid concentrations in serum phospholipids, especially eicosapentaenoic acid (EPA), docosahexaenoic acid (DHA), alpha-linolenic acid (ALA), linoleic acid (LA), dihomo-γ-linolenic acid (DGLA), and arachidonic acid (AA), were associated with risk of incident all-cause dementia and AD. Results. During the follow-up window of seven years, 233 participants developed dementia. Higher concentrations of EPA were associated with a lower incidence of AD (hazard ratio (HR) 0.76 (95% CI 0.63; 0.93)). We also observed that higher concentrations of EPA were associated with a decreased risk for all-cause dementia (HR 0.76 (95% CI 0.61; 0.94)) and AD (HR 0.66 (95% CI 0.51; 0.85)) among apolipoprotein E ε4 (APOE ε4) non-carriers but not among APOE ε4 carriers. No other fatty acids were significantly associated with AD or dementia. Conclusions. Higher concentrations of EPA were associated with a lower risk of incident AD. This further supports a beneficial role of n-3 PUFAs for cognitive health in old age.

Perilla frutescens seeds are rich in Omega-3 fatty acids which are important for human health. Intake of fatty acids depends on their presence in popular foods such as white bread. Current study evaluates the replacement of wheat flour by whole perilla at 1, 3 and 5% in white bread processing and its impacts on chemical and sensorial attributes, underscoring Omega-3 amounts. The use of whole perilla increases the Omega-3 content in white bread, balances the ratio n-6/n-3, decreases the specific volume, and maintains the concentration of phenolic compounds and antioxidant activity. The formulation with 1% whole perilla has a better acceptability and supplies 5.63 and 8.19% of the American recommended daily intake of alpha-linolenic acid for adult males and females, respectively.

Abstract. The ability of the cold-water coral Lophelia pertusa to exploit different food sources was investigated under standardized conditions in a flume. The tested food sources, dissolved organic matter (DOM, added as dissolved free amino acids), bacteria, algae, and zooplankton (Artemia) were deliberately enriched in 13C and 15N. The incorporation of 13C and 15N was traced into bulk tissue, fatty acids, hydrolysable amino acids, and the skeleton (13C only) of L. pertusa. Incorporation rates of carbon (ranging from 0.8–2.4 μg C g−1 DW d–1) and nitrogen (0.2–0.8 μg N g−1 DW d–1) into coral tissue did not differ significantly among food sources indicating an opportunistic feeding strategy. Although total food assimilation was comparable among sources, subsequent food processing was dependent on the type of food source ingested and recovery of assimilated C in tissue compounds ranged from 17% (algae) to 35% (Artemia). De novo synthesis of individual fatty acids by L. pertusa occurred in all treatments as indicated by the 13C enrichment of individual phospholipid-derived fatty acids (PLFAs) in the coral that were absent in the added food sources. This indicates that the coral might be less dependent on its diet as a source of specific fatty acids than expected, with direct consequences for the interpretation of in situ observations on coral nutrition based on lipid profiles.
