Mozaffarian D, Rimm EB. Fish intake, contaminants, and human health: evaluating the risks and the benefits. JAMA. 2006;296(15):1885-1899. PMID 16882980(verification gap: A 2006 narrative synthesis, not a systematic review, and it predates the large randomised omega-3 trials, so it is weighted as background rather than as current trial evidence.) Structured evidence synthesis of benefits and contaminant risks of fish intake, combining cohort findings with exposure and toxicology estimates. · weight 0.2 · Modest fish intake (one to two servings a week) was associated with about 36% lower coronary death risk, and roughly 250 mg a day of EPA and DHA appeared sufficient for primary prevention. The authors concluded benefits outweigh risks for adults, and advised women of childbearing age and nursing mothers to eat two seafood servings a week while limiting a few high-mercury species and consulting local advisories for locally caught fish.
Abdelhamid AS, Brown TJ, Brainard JS, Biswas P, Thorpe GC, Moore HJ, et al. Omega-3 fatty acids for the primary and secondary prevention of cardiovascular disease. Cochrane Database Syst Rev. 2020;3(3):CD003177. PMID 32114706(verification gap: Almost all evidence is from capsule supplements and enriched foods rather than eating fish, so it does not test the food itself.) Cochrane systematic review and meta-analysis of 86 randomised controlled trials with 162,796 participants, 12 to 88 months long, testing long-chain omega-3 supplementation, ALA, or omega-3 rich foods and dietary advice. · weight 1.0 · Moderate- and high-certainty evidence suggested that increasing EPA and DHA has little or no effect on mortality or cardiovascular health, and that earlier suggestions of benefit came from trials at higher risk of bias. Long-chain omega-3 reduced triglycerides by about 15% in a dose-dependent way. Increasing ALA probably makes little or no difference to mortality.
