MIND Diet

What it is

MIND (Mediterranean–DASH Intervention for Neurodegenerative Delay) is operationalised as 10 brain-healthy foods to emphasise and 5 unhealthy foods to limit. Higher adherence scores associated with slower cognitive decline and lower Alzheimer’s risk in Rush Memory and Aging Project cohorts.

The 10 brain-healthy foods

• Green leafy vegetables (≥6 servings/week).
• Other vegetables (≥1/day).
• Berries (≥2 servings/week; specifically berries, not other fruit).
• Nuts (≥5 servings/week).
• Olive oil (primary added fat).
• Whole grains (≥3 servings/day).
• Fish (≥1 serving/week).
• Beans (≥3 servings/week).
• Poultry (≥2 servings/week).
• Wine (1 glass/day or less — this guideline pre-dates more cautious recent thinking on alcohol).

The 5 to limit

• Red meat, butter/margarine, cheese, pastries/sweets, fried/fast food.

What the RCT showed

The 3-year MIND-diet RCT (Barnes et al., 2023, N=604, mild cognitive concerns, with weight loss) did not show a significant cognitive benefit beyond the calorie-restricted control. The observational signal remains; the causal interpretation is weaker.

Practical takeaway

Even if MIND doesn’t separate from generic healthy patterns, the underlying message — leafy greens, berries, fish, olive oil, nuts — is consistent with the rest of cardiometabolic-prevention nutrition.
