What Defines the MIND Diet
How do researchers define and score the MIND diet, and what foods make up the pattern?
MIND Diet Companion gathers the studies that define and score the MIND eating pattern here — the hybrid of the Mediterranean and DASH diets, its 15 dietary components, and how adherence is measured.
📄 MIND Diet Associated With Reduced Incidence of Alzheimer's Disease
Morris MC, et al. — Alzheimer's & Dementia, 2015 · pubmed / 25681666
MIND Diet Companion research surfaced this report because it covers how the MIND diet is defined and scored. The 2015 paper that introduced the pattern built a 15-component score — 10 brain-healthy groups (green leafy vegetables, other vegetables, berries, nuts, beans, whole grains, fish, poultry, olive oil, and wine) and 5 to limit (red meat, butter and margarine, cheese, pastries and sweets, and fried or fast food) — and in a prospective cohort of 923 older adults reported a hazard ratio of 0.47 (95% CI 0.26 to 0.76) for incident Alzheimer's disease in the highest versus lowest score tertile. The finding is an observational association from a single community cohort, not a demonstration of cause.
What it examines: the definition of the 15-component MIND diet score and its association with incident Alzheimer's disease. Why it's in the MIND Diet Companion research index: the origin paper that defines the MIND diet pattern and its scoring.
📄 Validation of a MIND Diet Screener in Older Adults
Dempsey DA, et al. — Alzheimer's & Dementia, 2025 · pubmed / 41065051
MIND Diet Companion research surfaced this report because it covers how MIND adherence is measured in practice. The 2025 study validated a brief 15-item MIND diet screener against a full food-frequency questionnaire in 92 older adults, reporting a correlation of r = 0.71 and a weighted kappa of 0.67, with 63% of people classified into the same category and 1% grossly misclassified. It is a measurement-validation study in a small sample, not a test of any health outcome.
What it examines: the accuracy of a short 15-item MIND diet screener against a full food-frequency questionnaire. Why it's in the MIND Diet Companion research index: the instrument researchers use to score MIND adherence quickly.
📄 The MIND Diet and Cognitive Health: A Systematic Review
Tse JHW, et al. — The Journal of Nutrition, Health & Aging, 2025 · pubmed / 40644764
MIND Diet Companion research surfaced this report because it covers how the MIND diet has been studied overall. The 2025 systematic review of 39 articles from 14 countries found positive associations with global cognition in 14 of 19 studies and protection against dementia or Alzheimer's in 10 of 11, while stating that randomized-trial results remain mixed and that scoring methods vary across studies. It summarizes a body of mostly observational work and does not itself establish cause.
What it examines: the overall pattern of findings across 39 MIND diet studies, observational and randomized. Why it's in the MIND Diet Companion research index: a recent synthesis of the MIND diet literature that also flags its limits.

Frequently Asked Questions
What is the MIND diet?
The MIND diet is a hybrid of the Mediterranean and DASH diets introduced in 2015, scored on 15 components — 10 to favor (such as green leafy vegetables, berries, nuts, whole grains, fish, and olive oil) and 5 to limit (red meat, butter, cheese, sweets, and fried food) (Morris, 2015). This summarizes research and is not medical advice.
How is the MIND diet scored?
Researchers score 15 dietary components from food-frequency data; a validated 15-item screener agreed closely with a full questionnaire (r = 0.71; Dempsey, 2025). Higher scores mean closer adherence.
Does the MIND diet prevent Alzheimer's?
The original cohort linked the highest MIND scores to lower incidence of Alzheimer's disease (hazard ratio 0.47; Morris, 2015), but these are observational associations, and randomized-trial results are mixed (Tse, 2025).
How good is the evidence behind the MIND diet?
A 2025 review of 39 studies found mostly positive observational associations (14 of 19 for global cognition) but noted that randomized trials are mixed and scoring is inconsistent (Tse, 2025). Observational associations are not proof of cause.
