Diet‐Driven Metabolite Patterns Link the MIND Diet to Dementia Biomarkers
Diandra N. Denier‐Fields, Ruocheng Dong, Briana L Rocha, Nathaniel A. Chin, Ramiro Eduardo Rea Reyes, Rachael E. Wilson, Erin McMullen Jonaitis, Rebecca E. Langhough et al.. Alzheimer s & Dementia, 2025-12-01
Topic: Risk, prevention and care in population studies
Sample characteristics are shown in Table 1. The first four principal components (PCs) explained 38% of the variance in the MIND diet-associated metabolites. Figure 1 presents the top seven metabolites for each PC. Regression models (Table 2) identified significant positive PC-biomarker associations: PC1 with ptau217 and NfL; PC2 with GFAP and NfL; PC3 with all four biomarkers; and PC4 with ptau217. Mediation analysis will examine whether these PCs mediate the relationship between the MIND diet and plasma biomarkers. MIND diet-associated plasma metabolite groups correlate with plasma biomarkers of AD and neurodegeneration. These groups of metabolites include essential amino acids, omega-3 fatty acids, plant and gut microbe-derived metabolites, and sphingolipids. These findings highlight the potential importance of dietary interventions in modulating metabolic pathways linked to dementia biomarkers.
Key findings
- Sample characteristics are shown in Table 1.
- The first four principal components (PCs) explained 38% of the variance in the MIND diet-associated metabolites.
- Figure 1 presents the top seven metabolites for each PC.
- Regression models (Table 2) identified significant positive PC-biomarker associations: PC1 with ptau217 and NfL; PC2 with GFAP and NfL; PC3 with all four biomarkers; and PC4 with ptau217.
- Mediation analysis will examine whether these PCs mediate the relationship between the MIND diet and plasma biomarkers.
Why it matters
This study found that groups of MIND diet-associated plasma metabolites correlate with plasma biomarkers of Alzheimer's disease and neurodegeneration, including ptau217, NfL, and GFAP. It states that mediation analysis will examine whether these metabolites mediate the relationship between the MIND diet and plasma biomarkers, so these findings highlight potential metabolic pathways rather than a proven prevention or treatment.
