The Claim
Among older adults aged 81 and older with the APOE ε4 gene variant, consuming one or more seafood meals per week is associated with a slower rate of decline in global cognitive function, semantic memory, and perceptual speed over a period of nearly five years.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Eating seafood at least once a week might help older adults with a specific gene variant keep their memory and thinking skills sharper for longer, compared to those who don't eat seafood as often.
See the scientific wording
Among older adults aged 81 and older with the APOE ε4 gene variant, consuming one or more seafood meals per week is associated with a slower rate of decline in global cognitive function, semantic memory, and perceptual speed over nearly five years, suggesting that dietary seafood may help protect cognitive abilities in this genetically vulnerable population.
What the research says
1 studyStudy: APOE ε4 and the associations of seafood and long-chain omega-3 fatty acids with cognitive decline
For older people with a specific gene that raises dementia risk, eating seafood once a week or more was linked to slower memory and thinking decline over nearly five years. This suggests seafood might help protect their brains.
