    MIND diet associated with reduced incidence of Alzheimer's disease
    (Elsevier BV, 2015) Morris, Martha Clare; Tangney, Christy C.; Wang, Yamin; Sacks, Frank; Bennett, David A.; Aggarwal, Neelum T.
    INTRODUCTION: In a previous study, higher concordance to the MIND diet, a hybrid Mediterranean-Dietary Approaches to Stop Hypertension diet, was associated with slower cognitive decline. In this study we related these three dietary patterns to incident Alzheimer's disease (AD). METHODS: We investigated the diet-AD relations in a prospective study of 923 participants, ages 58 to 98 years, followed on average 4.5 years. Diet was assessed by a semiquantitative food frequency questionnaire. RESULTS: In adjusted proportional hazards models, the second (hazards ratio or HR = 0.65, 95% confidence interval or CI 0.44, 0.98) and highest tertiles (HR = 0.47, 95% CI 0.26, 0.76) of MIND diet scores had lower rates of AD versus tertile 1, whereas only the third tertiles of the DASH (HR = 0.61, 95% CI 0.38, 0.97) and Mediterranean (HR = 0.46, 95% CI 0.26, 0.79) diets were associated with lower AD rates. DISCUSSION: High adherence to all three diets may reduce AD risk. Moderate adherence to the MIND diet may also decrease AD risk.

    MIND diet slows cognitive decline with aging
    (Elsevier BV, 2015) Morris, Martha Clare; Tangney, Christy C.; Wang, Yamin; Sacks, Frank; Barnes, Lisa L.; Bennett, David A.; Aggarwal, Neelum T.
    INTRODUCTION: The Mediterranean and dash diets have been shown to slow cognitive decline; however, neither diet is specific to the nutrition literature on dementia prevention. METHODS: We devised the Mediterranean-Dietary Approach to Systolic Hypertension (DASH) diet intervention for neurodegenerative delay (MIND) diet score that specifically captures dietary components shown to be neuroprotective and related it to change in cognition over an average 4.7 years among 960 participants of the Memory and Aging Project. RESULTS: In adjusted mixed models, the MIND score was positively associated with slower decline in global cognitive score (β = 0.0092; P < .0001) and with each of five cognitive domains. The difference in decline rates for being in the top tertile of MIND diet scores versus the lowest was equivalent to being 7.5 years younger in age. DISCUSSION: The study findings suggest that the MIND diet substantially slows cognitive decline with age. Replication of these findings in a dietary intervention trial would be required to verify its relevance to brain health.
