Overview

• Participants who enhanced their adherence to the MIND diet over 10 years experienced a 25% lower risk of Alzheimer’s and related dementias compared with those whose adherence declined.
• High initial adherence to the MIND diet was linked to a 9% overall reduction in dementia risk, with a 13% decrease observed among Black, Latino and White participants.
• Risk reductions were consistent across age groups, indicating that adopting or improving the MIND diet in midlife offers benefits regardless of when individuals start.
• The protective association was weaker among Asian American and Native Hawaiian participants, suggesting the need for culturally tailored dietary frameworks.
• Results derive from the Multiethnic Cohort Study of nearly 93,000 U.S. adults aged 45–75, in which over 21,000 cases of Alzheimer’s or related dementias were recorded.
