Omega-3 fatty acids are the most widely used nonvitamin supplement in the United States by both adults and children. 1 We presently lack data from adequately powered controlled trials to say definitively whether omega-3 (n-3) fatty acids are efficacious as mono-therapy in the treatment of major depressive disorder (MDD). Data are inconclusive regarding their efficacy as adjunctive therapy in MD...

Omega-3 fatty acids are important for several neuronal and cognitive functions. Altered omega-3 fatty acid status has been implicated in reduced resistance to stress and mood disorders. We therefore evaluated the effects of repeated restraint stress (6 h/day for 21 days) on adult rats fed omega-3 deficient, control or omega-3 enriched diets from conception. We measured body weight, plasma corti...

In the OMEGA study on patients after myocardial infarction, 1 the anticipated statistical power of 80% was not reached, which was attributed to the low incidence of sudden cardiac death in patients receiving current guideline-adjusted medical treatment. To detect an improvement of clinical outcome by omega-3 fatty acids, it is considered important to focus on patients with poor heart function. ...

Recent data suggest that omega-3 fatty acids may be effective in epilepsy, cardiovascular disorders, arthritis, and as mood stabilizers for bipolar disorder; however, the mechanism of action of these compounds is unknown. Based on earlier studies implicating omega-3 fatty acids as inhibitors of protein kinase C activity in intact cells, we hypothesized that omega-3 fatty acids may act through d...

Objectives: Considering the increasing prevalence of depression in modern societies and the positive effects of omega-3 polyunsaturated fatty acids on depression, this study aims to investigate the omega-3 and omega-6 content of various foodstuffs, prescribed or prohibited by Iranian Traditional Medicine (ITM). Materials and Methods: Firstly, reliable sources of Iranian Traditional Medicine wer...

Several sources of information suggest that human beings evolved on a diet with a ratio of omega-6 to omega-3 essential fatty acids (EFA) of approximately 1 whereas in Western diets the ratio is 15/1-16.7/1. Western diets are deficient in omega-3 fatty acids, and have excessive amounts of omega-6 fatty acids compared with the diet on which human beings evolved and their genetic patterns were es...

OPINION STATEMENT Early secondary prevention trials of fish and omega-3 polyunsaturated fatty acid (PUFA) capsules reported beneficial effects on cardiovascular disease (CVD) outcomes, including all-cause mortality and sudden cardiac death. These clinical findings, as well as observational and experimental data, demonstrated that omega-3 PUFAs reduced the risk of coronary outcomes and overall m...

A high omega-6/omega-3 ratio, as is found in today's Western diets, promotes the pathogenesis of many chronic diseases, including cardiovascular disease. Increased dietary intake of linoleic acid (LA) leads to oxidation of low-density lipoprotein (LDL), platelet aggregation, and interferes with the incorporation of essential fatty acids (EFA) in cell membrane phopholipids. Both omega-6 and omeg...

Omega-3 fatty acid supplemented total parenteral nutrition improves the clinical outcome of patients undergoing certain operations; however, its benefits for patients with hepatitis type B virus (HBV)-associated hepatocellular carcinoma (HCC) who have undergone hepatectomy are still not clear. The aim of this study was to evaluate the effect of omega-3 fatty acid supplemented total parenteral n...

BACKGROUND Depression is a common disorder affecting 10-15% women in the postpartum period. Postpartum depression can disrupt early mother-infant interaction, and constitutes a risk factor for early child development. Recently, attention has been drawn to the hypothesis that a low intake of seafood in pregnancy can be a risk factor for postpartum depression. Seafood is a unique dietary source o...
