Presently alpha-linolenic acid (ALA) is the most widely used vegetarian LC3PUFA, but only marginal amounts are converted into eicosapentaenoic (EPA) and docosahexaenoic acid (DHA); both of which are strongly related to human health. Currently, fish oils represent the most prominent dietary sources of EPA and DHA; however, these are unsuitable for vegetarians. Alternative sources include flaxseed, echium, walnut, and algal oil but their conversion to EPA and DHA must be considered. The present… Expand

Bioavailability and conversion of plant based sources of omega-3 fatty acids - a scoping review to update supplementation options for vegetarians and vegans.
TLDR
Preliminary advice for vegetarians and vegans is regular consumption of preformed EPA and DHA supplements may help maintain optimal O3I, and further studies should establish optimum EPA andDHA ratios and dosages in vegetarian and vegan populations. Expand
Alternative origins for omega-3 fatty acids in the diet
TLDR
Alternative sources hold the potential to meet the demand for fish and fish oils, while reducing the negative impact on fish stocks and introducing plant-derived omega-3 to livestock feeds may enhance the Omega-3 LC PUFA content within meat and dairy products. Expand
Healthy yogurt fortified with n-3 fatty acids from vegetable sources.
TLDR
The concentration of n-3 polyunsaturated fatty acids (PUFA) in yogurt was increased using 5 different vegetable oils obtained from flaxseed, Camelina sativa, raspberry, blackcurrant, and Echium plantagineum to produce fortified yogurts accepted by consumers. Expand
Hypolipidemic Effect of Alpha-Linolenic Acid Rich Blended and Interesterified of Refined Palm Olein Oil With Flaxseed Oil as Compared to Native Oil Fed Rats
Omega-3 and omega-6 are two types of dietary polyunsaturated fatty acids (PUFA) and considered as essential fatty acids. These essential fatty acids cannot synthesise by mammals [1]. Hence it must be… Expand
Bioavailability of long-chain n-3 fatty acids from enriched meals and from microencapsulated powder
TLDR
Bioavailability of LC n-3 PUFAs in encapsulated powder is very similar to the bioavailability in ready-to-eat meals enriched with liquid fish oil, and encapsulated Powder can be considered useful to increase LC n -3 PUFA concentrations in blood. Expand
Development of a Natural Product Rich in Bioavailable Omega-3 DHA from Locally Available Ingredients for Prevention of Nutrition Related Mental Illnesses
TLDR
Findings indicate that ready-to-use natural food rich in preformed Omega-3 DHA and EPA can be developed from locally available ingredients. Expand
The development of vegetarian omega-3 oil in water nanoemulsions suitable for integration into functional food products
Abstract Global trends show that habitual omega-3 intakes are short of recommended guidelines, particularly among vegetarians and vegans. The potential health implications of low long chain omega-3… Expand
Microalgae: An alternative natural source of bioavailable omega-3 DHA for promotion of mental health in East Africa
Abstract Mental health illness associated with poor nutrition is a serious public concern worldwide. The most at risk individuals are children and adolescents in the developing world. Deficiencies in… Expand
A diet enriched with Mugil cephalus processed roes modulates the tissue lipid profile in healthy rats: a biochemical and chemometric assessment.
TLDR
The overall data suggest that mullet bottarga may be considered as a natural bioavailable source of n-3 PUFA and qualify it as a traditional food product with functional properties and a potential functional ingredient for preparation ofn-3PUFA enriched foods. Expand
The oxidative stability of omega-3 oil-in-water nanoemulsion systems suitable for functional food enrichment: A systematic review of the literature
TLDR
Quillaja saponin is a promising natural emulsifier that can produce nanoemulsion systems with equivalent/increased oxidative stability in comparison to other emulsifiers, which is useful as consumers are demanding natural, cleaner label food products. Expand

Achieving optimal essential fatty acid status in vegetarians: current knowledge and practical implications.
TLDR
Total n-3 requirements may be higher for vegetarians than for nonvegetarians, as vegetarians must rely on conversion of ALA to EPA and DHA, although the response is generally less for ALA than for EPA andDHA. Expand
Bioavailability of omega-3 essential fatty acids from perilla seed oil.
TLDR
Enteric-coating (Entrox), which improves stability of omega-3 capsules, has been shown to facilitate fish oil absorption after chronic treatment, and significantly greater increases in plasma ALA levels from baseline to 24h were observed after ingestion of Entrox vs. non-coated product, suggesting a possible benefit of Entox with long-term treatment.

TLDR
Preformed DHA in the diet of omnivores explains the relatively higher proportion of this fatty acid in blood and tissue lipids compared with vegetarians. Expand
UK Food Standards Agency alpha-linolenic acid workshop report.
TLDR
There is a need to prove the efficacy of ALA supplementation on cardiovascular disease, before further investigating effects on cardiovascular risk factors, and the possibility of feeding livestock ALA-rich oils to provide a means of increasing the dietary intake in human consumers of EPA and DHA. Expand
N-3 Omega fatty acids: a review of current knowledge.
TLDR
This review will attempt to outline the current position of n-3 omega fatty acids in the field of clinical nutrition and healthcare and outline the studies needed to determine whether there are significant advantages in taking them as food supplement without any adverse effects. Expand
Understanding omega-3's.
TLDR
This document will provide an overview of omega-3 fatty acids with a focus on specific sources, metabolism, safety issues, and their potential indication for cardiovascular prevention. Expand
Dietary echium oil increases plasma and neutrophil long-chain (n-3) fatty acids and lowers serum triacylglycerols in hypertriglyceridemic humans.
TLDR
Dietary plant oils rich in stearidonic acid are metabolized to longer-chain, more unsaturated (n-3) PUFA, and these oils appear to possess hypotriglyceridemic properties typically associated with fish oils. Expand
Omega-3 fatty acids and coronary heart disease risk: clinical and mechanistic perspectives.
TLDR
The potential mechanisms by which omega-3 fatty acids reduce cardiovascular disease risk are reviewed, including prevention of arrhythmias as well as lowering heart rate and blood pressure, decreasing platelet aggregation, and lowering triglyceride levels. Expand
A practical approach to increasing intakes of n-3 polyunsaturated fatty acids: use of novel foods enriched with n-3 fats
Objectives: To assess the effects of providing a wide range of foodstuffs containing n-3 polyunsaturated fatty acids (PUFA), occurring naturally or from fortification, on intake and blood and tissue… Expand
Dietary intake of stearidonic acid-enriched soybean oil increases the omega-3 index: randomized, double-blind clinical study of efficacy and safety.
TLDR
SDA-enriched soybean oil is a land-based n-3 fatty acid that is a sustainable approach to increasing tissue concentrations of long-chain polyunsaturated n- 3 fatty acids. Expand
