The Claim

There is no significant association between erythrocyte membrane levels of long-chain n–3 fatty acids (including DHA and DPA) and cognitive performance in 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.

In plain English

Studies show that having more of certain healthy fats in your red blood cells doesn't seem to make your memory or thinking any better if you're an older adult who's otherwise healthy.

See the scientific wording

No significant association exists between erythrocyte membrane levels of long-chain n–3 fatty acids (including DHA and DPA) and cognitive performance in healthy older adults, contradicting the hypothesis that these fatty acids support cognitive function 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 with more omega-3 fatty acids in their blood didn’t perform better on memory or thinking tests, and eating more fish didn’t help either—so it doesn’t look like these fats boost brainpower in older people.
