Highlights
- The MIND diet combines the Mediterranean and DASH diets with a brain focus.
- It emphasizes leafy greens, berries, nuts, beans, whole grains, fish, and olive oil.
- It limits red meat, butter, cheese, sweets, and fried food.
- Observational studies link it with lower Alzheimer's risk and slower decline.
Most diets are designed to help you lose weight or protect your heart. The MIND diet is different. It was created specifically with the brain in mind, combining the best of two well-researched eating patterns to support memory and thinking as we age.
Since it was introduced in 2015, the MIND diet has received a lot of attention, and it's consistently ranked among the healthiest eating plans. This guide explains what the MIND diet is, what you eat (and limit), what research shows, and simple ways to start following it.
What Does MIND Stand For?
MIND stands for Mediterranean-DASH Intervention for Neurodegenerative Delay. It's a blend of two eating patterns:
- The Mediterranean diet: based on traditional eating in countries like Greece and Italy, rich in vegetables, fruit, whole grains, legumes, fish, nuts, and olive oil
- The DASH diet: short for Dietary Approaches to Stop Hypertension, designed to lower blood pressure
The MIND diet takes elements of both and places special emphasis on foods linked to brain health in research, particularly leafy green vegetables and berries.
Who Created the MIND Diet?
The MIND diet was developed by nutritional epidemiologist Dr. Martha Clare Morris and her colleagues at Rush University Medical Center in Chicago. They reviewed years of research on diet and brain health and designed an eating pattern around the foods most strongly associated with protecting the brain.
The 10 Brain-Healthy Food Groups
The MIND diet encourages these foods, with suggested amounts:
- Green leafy vegetables: at least six servings a week (spinach, kale, collards, salad greens)
- Other vegetables: at least one serving a day
- Berries: at least two servings a week (blueberries and strawberries are favorites)
- Nuts: five or more servings a week
- Beans and legumes: at least three or four meals a week
- Whole grains: three or more servings a day
- Fish: at least once a week
- Poultry: at least twice a week
- Olive oil: as your main cooking oil
- Wine: the original plan allowed up to one glass a day, but many experts now say there's no need to drink for brain health, and non-drinkers shouldn't start
The 5 Food Groups to Limit
- Red meat: fewer than four servings a week
- Butter and stick margarine: less than a tablespoon a day
- Cheese: less than one serving a week
- Pastries and sweets: fewer than five servings a week
- Fried or fast food: less than once a week
These foods are high in saturated fat, added sugar, or both, which are linked with poorer heart and brain health.
Why Berries and Leafy Greens?
Unlike the Mediterranean diet, which encourages fruit in general, the MIND diet specifically highlights berries. Research has linked berries, rich in antioxidants called flavonoids, with slower cognitive decline. Similarly, leafy greens are packed with folate, vitamin K, lutein, and other nutrients associated with better memory in older adults.
What Does the Research Show?
The Original Studies
In 2015, Morris and colleagues followed nearly 1,000 older adults for several years. They found that people who followed the MIND diet most closely had a 53 percent lower risk of developing Alzheimer's disease than those who followed it least. Even people who followed it moderately well had about a 35 percent lower risk.
A related study found that people who closely followed the MIND diet had slower cognitive decline, equivalent to being about seven and a half years younger in brain age.
Later Research
Other observational studies in different countries have also linked the MIND diet with better cognitive health and lower dementia risk. A study of brain autopsies found that people who followed the diet more closely had better cognitive function before death, regardless of the amount of Alzheimer's-related changes in their brains, suggesting the diet may help build resilience.
The MIND Trial
In 2023, researchers published a three-year randomized trial in The New England Journal of Medicine. Participants followed either the MIND diet or a control diet, and both groups also cut calories slightly. Both groups improved their thinking test scores, and there was no significant difference between them.
Researchers noted that the control group also improved its diet during the study, and that three years may be too short to see differences in cognitive decline. The takeaway: a healthier diet overall, combined with modest weight loss, appeared to benefit both groups.
Benefits Beyond the Brain
Because the MIND diet combines two heart-healthy eating patterns, it may also help:
- Lower blood pressure
- Improve cholesterol levels
- Reduce the risk of heart disease and stroke
- Support healthy weight
- Lower the risk of type 2 diabetes
All of these support brain health too.
Why the MIND Diet Is Easy to Follow
Many people find the MIND diet more flexible than other eating plans:
- No calorie counting is required
- No foods are completely banned
- You don't have to follow it perfectly to benefit
- It uses everyday, affordable foods
Research suggests even moderate adherence may help, so small changes count.
Simple Ways to Start
- Eat a salad a day: an easy way to meet the leafy greens goal
- Keep frozen berries: add them to breakfast or yogurt
- Snack on nuts: a small handful most days
- Add beans: to soups, chili, salads, and wraps
- Swap butter for olive oil: for cooking and on bread
- Choose whole grains: oatmeal, brown rice, whole-wheat bread
- Plan a fish night: once or twice a week
- Save sweets and fried foods for occasional treats
A Sample MIND Diet Day
- Breakfast: Oatmeal with blueberries and chopped walnuts
- Lunch: Large spinach salad with chickpeas, cucumber, tomatoes, and olive oil dressing, with whole-grain bread
- Snack: A handful of almonds
- Dinner: Grilled chicken or salmon with roasted vegetables and brown rice
- Dessert: Fresh strawberries
If you eat out often, look for dishes built around vegetables, beans, fish, or chicken, ask for olive oil instead of butter, and choose fruit for dessert. Small, consistent choices add up over time.
Pair the MIND Diet With Other Brain Habits
Diet is one piece of the brain health puzzle. For the greatest benefit, combine it with:
- Regular physical activity
- Seven to nine hours of sleep
- Social connection
- Stress management
- Keeping your mind active through learning, reading, and brain games
Frequently Asked Questions
Is the MIND diet good for everyone?
It's a balanced, healthy eating pattern suitable for most adults. Talk to your doctor if you have specific dietary needs.
Do I have to drink wine on the MIND diet?
No. Many experts now advise that there's no need to drink alcohol for brain health.
How is the MIND diet different from the Mediterranean diet?
It specifically emphasizes leafy greens and berries and sets limits on foods like butter, cheese, and sweets.
Can the MIND diet prevent Alzheimer's?
No diet can guarantee prevention, but research links the MIND diet with lower risk and slower cognitive decline.
Key Takeaways
- The MIND diet combines the Mediterranean and DASH diets with a brain focus.
