Abstract

Objective: Diet may reduce Alzheimer’s dementia risk and slow cognitive decline, but the understanding of the relevant neuropathologic mechanisms remains limited. The association of dietary patterns with Alzheimer’s disease (AD) pathology has been suggested using neuroimaging biomarkers. This study examined the association of MIND and Mediterranean dietary patterns with beta-amyloid load, phosphorylated tau tangles, and global AD pathology in postmortem brain tissue of older adults. Methods: Autopsied participants of the Rush Memory and Aging Project) with complete dietary information (collected through a validated food frequency questionnaire) and AD pathology data (beta-amyloid load, phosphorylated tau tangles, and global AD pathology [summarized neurofibrillary tangles, neuritic and diffuse plaques]) were included in this study. Linear regression models controlled for age at death, sex, education, APO-ε4 status, and total calories were used to investigate the dietary patterns (MIND and Mediterranean diet) and dietary components associated with AD pathology. Further effect modification was tested for APO-ε4 status and sex. Results: Among our study participants (N=581, age at death: 91.0 ± 6.3 years; mean age at first dietary assessment: 84.2 ±5.8; 73% female; 6.8 ± 3.9 years of follow-up) dietary patterns were associated with lower global AD pathology (MIND: β= -0.022, p=0.034, standardized β=-2.0; Mediterranean: β=-0.007, p=0.039, standardized β=-2.3) and specifically less beta-amyloid load (MIND: β=-0.068, p=0.050, standardized β=-2.0; Mediterranean: β=-0.040, p=0.004, standardized β=-2.9). The findings persisted when further adjusted for physical activity, smoking, and vascular disease burden. The associations were also retained when participants with mild cognitive impairment or dementia at the baseline dietary assessment were excluded. Those in the highest tertile of green leafy vegetables intake had less global AD pathology when compared to those in the lowest tertile (Tertile-3 vs. Tertile-1: β= -0.115, p=0.0038). Conclusion: The MIND and Mediterranean diets are associated with less postmortem AD pathology, primarily beta-amyloid load. Among dietary components, green leafy vegetables inversely correlate with AD pathology.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
