Eating style
MIND diet
A blend of the Mediterranean and DASH diets built around leafy greens, berries, beans and whole grains. What it includes, and what the evidence on brain health actually shows.
What it is
MIND stands for Mediterranean-DASH Intervention for Neurodegenerative Delay. Its designers combined the two diets and singled out foods that earlier studies had linked with slower cognitive decline. It works as a weekly score rather than a meal plan: there are no calorie targets, portion sizes or recipes built in.
The foods to eat often are whole grains (three or more servings a day), leafy greens (six or more a week), other vegetables (daily), nuts (five or more a week), beans (four or more meals a week), berries and poultry (twice a week each) and fish (weekly), with olive oil as the main added fat. Red meat, butter, cheese, pastries and sweets, and fried food are limited.
What the evidence shows
The diet became known through a 2015 observational study of 923 older adults followed for an average of 4.5 years. Those with the highest MIND scores had a 53% lower rate of Alzheimer’s disease than those with the lowest, and those in the middle a 35% lower rate. A study like this shows an association: people who eat this way differ in other ways too.
The first large trial was published in 2023. It assigned 604 older adults with a family history of dementia to the MIND diet or a control diet, both with mild calorie restriction, for three years. Cognition improved in both groups, with no significant difference between them on tests or on brain scans. Whether a longer trial would find one is not known.
How to use it
Treat it as a checklist for the week rather than a promise. Leafy greens most days, berries twice a week, beans in several meals, nuts as a snack and olive oil for cooking are changes that also fit the Mediterranean and DASH patterns, which have trial evidence behind them for cardiovascular risk and blood pressure.
Worth knowing
- The MIND diet has not been shown in a trial to prevent or delay dementia. If you are worried about your memory, see your doctor.
- The original score counted a daily glass of wine. Later trials dropped it, and alcohol is not needed to follow the diet.
Common questions
How is it different from the Mediterranean diet?
It singles out leafy greens and berries, asks for fish only once a week, and sets specific limits on butter, cheese, red meat, fried food and sweets.
Does the MIND diet help with weight loss?
It is not designed for it and sets no calorie targets. In the 2023 trial both groups lost weight because both were also asked to eat slightly fewer calories.
