Research summary
- Omega-3 fatty acids from fatty fish are supported by meta-analyses linking higher intake or blood levels to lower cardiovascular disease risk, alongside reviews on cognitive protection.
- However, the cognitive evidence is notably mixed: reviewed randomized trials of supplementation show benefit in some populations with mild cognitive impairment but not consistently in general or overweight populations, and one meta-analysis on dosage found effects on cardiovascular outcomes vary with the amount consumed.
- This is a case where cardiovascular benefit is reasonably well supported by converging meta-analyses, while cognitive benefit remains an active and less settled area of research, so the overall confidence is moderate rather than strong.
