The Claim

Greater fish consumption during childhood is associated with slower perceptual speed and simple/choice reaction time in older adulthood.

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

What the research says

Supports is higher

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

In plain English

Kids who eat more fish may grow up to be slower at quick thinking tasks like reacting to buttons or spotting changes, even though we don’t know why.

See the scientific wording

Greater fish consumption during childhood is associated with slower perceptual speed and simple/choice reaction time in older adulthood, suggesting early-life dietary patterns may have long-term, unexpected effects on cognitive processing speed, though this association remains correlational and unexplained by current data.

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 people who ate more fish as kids tended to react more slowly and process information more slowly when they got older, even though we don’t yet know why. So yes, the study backs up the idea that eating more fish as a child might have a surprising downside for brain speed later in life.
