Dietary magnesium intake and dementia risk in community-dwelling people aged 40-74 years: an 8-year cohort study.

ABSTRACT: Dietary magnesium (Mg) is a potentially modifiable factor in preventing dementia, but current evidence supporting this remains insufficient and inconclusive. This study aimed to determine whether dietary Mg is associated with the risk of dementia among middle-aged and older people.
