The Claim

Daily consumption of up to 30 grams of nuts is associated with a 12% lower risk of developing all-cause dementia over a mean follow-up period of 7.1 years in middle-aged and older adults, after adjustment for sociodemographic, lifestyle, and health factors including BMI, physical activity, smoking, alcohol use, and chronic disease burden.

In plain English

People who eat up to 30 grams of nuts every day have a 12% lower risk of developing any form of dementia over about 7 years compared to those who do not, even when accounting for differences in age, lifestyle, and health conditions.

See the scientific wording

Daily consumption of nuts (up to 30 grams per day) is associated with a 12% lower risk of developing all-cause dementia over a mean follow-up period of 7.1 years in middle-aged and older adults, independent of sociodemographic, lifestyle, and health factors such as BMI, physical activity, smoking, alcohol use, and chronic disease burden.

Why this might work

Eating nuts daily delivers compounds that calm inflammation and neutralize harmful molecules in the brain, which keeps brain cells healthy and working properly, reducing the chance of dementia.
