Salmon: benefits vs risks (2005)
Quantitative analysis of the benefits and risks of consuming farmed and wild salmon.
Overview
Foran JA et al.. J Nutr 2005 · PMID 16251623 · DOI 10.1093/jn/135.11.2639
The omega-3 benefit of salmon partly offsets contaminant risk; some farmed salmon was similar to wild.
Does the study support the specific claim? Partly · Methodological quality: moderate

2. Research question
Do omega-3 benefits outweigh contaminant risks for farmed vs wild salmon?
3. Study design and population
- Study design
- Risk assessment – Quantitative benefit-risk analysis (omega-3 benefit vs contaminant risk) for farmed and wild salmon
- Population
Modelled consumers
- Country
US-based analysis of multinational samples
- Period
2005
- Sample size
Salmon samples of Hites et al.
4. Methods and endpoints
- Exposure / intervention
EPA+DHA intake; contaminant exposure
- Comparator
Farmed vs wild; subgroups
- Endpoints
Benefit-risk ratios
- Statistical methods
Not stated in abstract
5. Actual results
- Results
Recommended EPA+DHA achievable while keeping acceptable non-cancer risk; not achievable solely from salmon at acceptable carcinogenic risk; benefit-risk ratio greater for wild than farmed as a group, but some farmed subgroups on par with wild.
- Absolute risks
not reported
- Authors' conclusion
Risk 'is partially offset by the fatty acid-associated health benefits'; vulnerable groups can choose least contaminated wild salmon or other n-3 sources.
6. Strengths
- Considers benefits
7. Weaknesses
- Same conservative cancer-risk framework
- Old samples
8. Risk of bias
- Orienting tool
- none applicable
- Type of assessment
- simplified assessment (abstract only)
- Full formal assessment
- no
- Overall risk of bias
- some concerns
- Rationale
As A-FSH-04.
9. Assessment of the statistical interpretation
Model-based ratios.
10. Relevance to the specific claim
Limits C-FSH-03.
11. Independent contrary findings
12. Transferability to Germany and Europe
Low.
13. Overall methodological judgement
Shows the archive's selection omits benefit-side findings of the same group.

- What the archive says about the study
Listed in bibliography only.
- A. What was actually studied?
Benefit-risk.
- B. What did the authors find?
Benefit partially offsets risk; some farmed subgroups similar to wild.
