^∗Spearman correlation analysis acted as a univariate analysis. ^†Partial correlation analysis adjusted for age, gender, and education years. Data are shown as the mean ± Standard deviation. FFQ: Food frequency questionnaire; MMSE: Mini-mental status examination; AD: Alzheimer disease; CSF: Cerebrospinal fluid; Aβ₄₂: β-Amyloid (1–42); Aβ₄₀: β-Amyloid (1–40).
