Hypothesis
Can we quantitatively analyze the net risk/benefit of individual fish species based on their methylmercury and omega-3 fatty acid content?
Conclusion
The study provides a framework for developing fish consumption advice that balances the benefits of omega-3 fatty acids against the risks of methylmercury.
Supporting Evidence
- Estimated omega-3 FA benefits outweigh MeHg risks for some species like farmed salmon and herring.
- Swordfish and shark were found to have higher MeHg risks.
- Separate advice is warranted for neurodevelopmental and cardiovascular risk groups.
Takeaway
Some fish are good for you because they have healthy fats, but others can be harmful because they have too much mercury. This study helps figure out which fish are safe to eat.
Methodology
The study identified dose-response relationships for methylmercury and omega-3 fatty acids and calculated the net risk/benefit for 16 commonly consumed fish species.
Limitations
The conclusions are tentative due to uncertainties in the underlying dose-response relationships.
Statistical Information
Confidence Interval
95% confidence interval, 8–21% reduction in CHD mortality per 100 mg/day omega-3 FA ingested.
