The Claim

Daily nut consumption is associated with a reduced risk of all-cause dementia in adults aged 60 and older, but not in adults younger than 60.

In plain English

Adults aged 60 and older who eat nuts daily have a lower risk of developing dementia from any cause compared to those who do not, while this association is not observed in younger adults.

See the scientific wording

Daily nut consumption is associated with a reduced risk of all-cause dementia in adults aged 60 and older, but not in younger adults, indicating that the protective effect may be more relevant in later life.

Why this might work

Eating nuts every day delivers compounds that calm inflammation and reduce damage from harmful molecules in the brain. These compounds also improve blood flow to the brain by cleaning up fats in the blood and helping blood vessels relax. Together, this keeps brain cells healthier and working longer, especially as people age.

  1. Study: Nut consumption is associated with a lower risk of all-cause dementia in adults: a community-based cohort study from the UK Biobank

    Eating a small handful of unsalted nuts every day was linked to a lower chance of getting dementia over 7 years, especially in older people — but the study didn’t break down the results by age, so we can’t be sure it’s only helpful for those 60+.
