One of the best ways to protect your brain is through your diet. What you eat has a big impact on how well your mind works. Researchers have found that the MIND diet is especially helpful for brain health. It combines the Mediterranean diet and the DASH diet. Together, they lower the risk of Alzheimer’s disease and dementia
The MIND diet was created to protect the brain from memory loss and thinking problems. Studies show that it lowers the risk of Alzheimer’s disease even in people who only follow it loosely. Other research links this diet to slower cognitive decline and better brain aging. The MIND diet is simple. You don’t have to count calories. Just focus on eating more of certain foods and less of others.
Healthy foods to eat often:
- Whole grains
- Green leafy vegetables (like spinach or kale)
- Beans
- Nuts
- Fish and poultry
- Berries
- Olive oil as your main fat
Unhealthy foods are not banned, but they should be limited. Here’s what to avoid:
- Try to eat red meat no more than four times a week.
- Keep sweets and pastries to five or fewer per week.
- Limit cheese, fried food, and fast food to one serving per week.
- Use butter sparingly, no more than 1 tablespoon a day
Changing your diet all at once can feel hard. Habit science shows that small steps work best. Try one of these ideas this week:
- Cut back slowly. If you eat sweets 6 days a week, reduce to 5 days.
- Add healthy foods. If you don’t usually eat leafy greens, add spinach or kale to two meals.
- Swap something. Try fruit instead of candy, grilled chicken instead of fried chicken, or olive oil instead of butter.
Over time, small diet changes add up to support memory, focus, and overall brain health.
