The diet of our ancestors was less dense in calories, being higher in fiber, rich in fruits, vegetables, lean meat, and fish. As a result, the diet was lower in total fat and saturated fat, but contained equal amounts of n-6 and n-3 essential fatty acids. Linoleic acid (LA) is the major n-6 fatty acid, and alpha-linolenic acid (ALA) is the major n-3 fatty acid. In the body, LA is metabolized to arachidonic acid (AA), and ALA is metabolized to eicosapentaenoic acid (EPA) and docosahexaenoic acid… 
Omega-3 Fatty Acids in Metabolism, Health, and Nutrition and for Modified Animal Product Foods
TLDR
Developing gene-modified oil crops to increase content of stearidonic acid supply holds promise to increase EPA synthesis in humans and domestic animals, and it seems possible that niche markets for products containing greater amounts of n-3 fatty acids can be developed without expensive protection processes and risks of decreased product quality.
Alpha-Linolenic and Linoleic Fatty Acids in the Vegan Diet: Do They Require Dietary Reference Intake/Adequate Intake Special Consideration?
TLDR
It is suggested that VGNs have a DRI-AI Special Consideration requirement for ALA and LA based on VGN dietary and biochemical indicators of status and suggestions to ensure that V GNs receive adequate intakes of LA and ALA are provided.
Co-expression of fat1 and fat2 in transgenic pigs promotes synthesis of polyunsaturated fatty acids
TLDR
The generated fat1–fat2 TG pigs can also serve as a large animal model for studying the roles of n-3 PUFAs in human development and health and provide a new strategy to produce n- 3 PUFA-rich meat for human consumption.
Long-chain Omega-3 Polyunsaturated Fatty Acids in Natural Ecosystems and the Human Diet: Assumptions and Challenges
TLDR
An attempt is made to reconsider the following assumptions of essential biomolecules, long-chain polyunsaturated fatty acids of the omega-3 family, which decrease with increasing eutrophication in aquatic ecosystems, and some of the above assumptions need to be substantially specified and changed.
Development of Rabbit Meat Products Fortified With n-3 Polyunsaturated Fatty Acids
TLDR
The recent studies indicate that the dietary inclusion from 3 to 6% of linseed might be considered as a way to achieve the enrichment of the meat with α-linolenic acid and to guarantee satisfactory product stability during further processing and storage.
Enriched eggs as a source of n-3 polyunsaturated fatty acids for humans
The aim of the research was to enrich eggs with n-3 polyunsaturated fatty acids by using plant oils and fish oil as dietary supplements in laying hens’ feed. The focus was put on the effect of the
Dose effect of α-linolenic acid on PUFA conversion, bioavailability, and storage in the hamster
TLDR
Dietary supply of ALA was therefore a very efficient means of improving the 20∶4n−6 to 20∵5n−3 balance, and bioconversion, dietary ALA failed to increase 22∶6n+3, decreased 20∷4n+6, and efficiently increased 20∬5n-3 (EPA) in RBC and cardiomyocytes, and EPA accumulation did not tend to plateau.
Oxidative stability of omega-3 polyunsaturated fatty acids enriched eggs.
TLDR
The study indicated that the n-3 PUFA in enriched eggs was relatively stable during storage and home cooking in the presence of antioxidants.

Differential effects of dietary methyl esters of long-chain saturated and polyunsaturated fatty acids on rat liver and adipose tissue lipogenesis.
TLDR
It is shown that Ci8:2 and Ci8-3 specifically inhibit rat liver fatty acid synthesis, independent of carbohydrate intake, and under these conditions adipose tissue lipogenesis was unaffected by low levels of dietary fat regardless of the degree of unsaturation.
Dietary substitution with an alpha-linolenic acid-rich vegetable oil increases eicosapentaenoic acid concentrations in tissues.
TLDR
The results indicate that alpha-LA-rich vegetable oils can be used in a domestic setting (in conjunction with a background diet low in LA) to elevate EPA in tissues to concentrations comparable with those associated with fish-oil supplementation.
Use of manufactured foods enriched with fish oils as a means of increasing long-chain n−3 polyunsaturated fatty acid intake
TLDR
Enriched manufactured foods were a feasible vehicle for increasing n−3 PUFA intake, however the nature of the foods provided as the n −3 vehicle may have contributed to the increased body weight and higher energy intakes which were adverse consequences of the intervention.
Lower ratio of n-3 to n-6 fatty acids in cultured than in wild fish.
TLDR
The ratio of n-3 to n-6 polyunsaturates was significantly lower in cultured than in wild fish (2 vs 7 in trout, 2 vs 5 in eel, and 6 vs 11 in salmon).
Egg yolk as a source of long-chain polyunsaturated fatty acids in infant feeding.
TLDR
With proper manipulation of the hens' diets, eggs could be produced with fatty acid composition similar to that of Greek eggs.

TLDR
Omega 3 fatty acids decrease the number and size of tumors and increase the time elapsed before appearance of tumors, which is essential for the normal functional development of the retina and brain, particularly in premature infants.
Does dietary linolenic acid influence blood pressure?
TLDR
Study of the long-term effects of dietary fat on blood pressure using adipose-tissue, fatty acid composition analysis in 399 free-living male subjects found dietary manipulation with n-3 fatty acids may be helpful in the treatment and prevention of hypertension.

TLDR
Dietary replacement of saturated fats by n-6 and especially n-3 PUFA but not monounsaturated fatty acids can reduce the likelihood of an ischemic event leading to sudden cardiac death.
