The Claim

Higher fish intake or elevated long-chain n–3 fatty acid levels have no beneficial effect on cognitive performance in cognitively healthy older adults.

Source: Cognitive performance in older adults is inversely associated with fish consumption but not erythrocyte membrane n-3 fatty acids.

Supports is higher

Support is ahead, but a single strong opposing study can change this.

Description
1 study reviewed
In plain English

Eating more fish or having more omega-3 fatty acids in your body doesn't seem to help your brain work better if you're an older adult who's already thinking clearly.

See the scientific wording

There is no evidence that higher fish intake or long-chain n–3 fatty acid levels benefit cognitive performance in cognitively healthy older adults, challenging the widely held belief that these dietary components support brain health in aging.

What the research says

1 study

  1. Study: Cognitive performance in older adults is inversely associated with fish consumption but not erythrocyte membrane n-3 fatty acids.

    This study found that older adults who ate more fish didn’t perform better on memory or thinking tests — and in some cases, they performed worse. So, the idea that fish helps your brain as you age isn’t supported by this research.
