Psychother Psychosom2019Systematic Review79 einflussreiche Zitationen
Major depressive disorder (MDD) is a complex mental illness with unmet therapeutic needs. The antidepressant effects of ω–3 polyunsaturated fatty acids (n–3 PUFAs) have been widely reported. The subcommittee of the International Society…
The influence of dietary and supplemental omega-3 fatty acids on the omega-3 index: A scoping review.
Front Nutr2023n=230Review69 einflussreiche Zitationen
<h4>Introduction</h4>The majority of the population do not consume adequate omega-3 fatty acids (n-3 FA), leading to global deficiencies, as evidenced by poor omega-3 status. An indicator of overall n-3 FA status, omega3-index (O3i) ≥8%…

Atherosclerosis2017Meta-Analysis68 einflussreiche Zitationen
<h4>Background and aims</h4>A recent 19-cohort meta-analysis examined the relationships between biomarkers of omega-3 fatty acids and risk for coronary heart disease (CHD). That study did not, however, report hazard ratios (HRs)…
Befund: A 1-SD increase in the Omega-3 Index was associated with a hazard ratio of 0.85 for coronary heart disease mortality.

Nutr Rev2022Meta-Analysis55 einflussreiche Zitationen
Context Randomized controlled trials (RCTs) testing supplementation with eicosapentaenoic (EPA) and docosahexaenoic (DHA) fatty acids have failed to provide evidence supporting a suggested inverse association between fish intake and…

Am J Clin Nutr2019n=1.422Study47 einflussreiche Zitationen
<h4>Background</h4>Supplemental long-chain omega-3 (n-3) fatty acids (EPA and DHA) raise erythrocyte EPA + DHA [omega-3 index (O3I)] concentrations, but the magnitude or variability of this effect is unclear.<h4>Objective</h4>The purpose…
