The Claim

Consumption of unsalted nuts is associated with a 17% lower risk of all-cause dementia compared to consumption of salted or roasted nuts, indicating that nut processing methods may influence dementia risk.

In plain English

People who eat unsalted nuts have a 17% lower risk of developing dementia compared to those who eat salted or roasted nuts, suggesting that how nuts are processed affects dementia risk.

See the scientific wording

Consumption of unsalted nuts, but not salted or roasted nuts, is associated with a 17% lower risk of all-cause dementia, suggesting that processing methods may influence the neuroprotective potential of nuts.

Why this might work

Eating unsalted nuts delivers antioxidants and healthy fats that enter the brain, calm overactive immune cells, and reduce damage from harmful molecules, which keeps brain cells working longer and prevents memory loss.

  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

    People who ate unsalted nuts every day had a 17% lower chance of getting dementia over 7 years, but those who ate salted or roasted nuts didn’t get the same benefit — so how the nuts are prepared might matter for brain health.
