1. Fatty Fish (Salmon, Mackerel, Sardines)
Fatty fish are rich in omega-3 fatty acids, especially DHA and EPA, which are essential for brain cell structure and communication. Studies show that people who eat fish regularly have slower cognitive decline and a lower risk of Alzheimer’s disease. Try eating grilled salmon or tuna twice a week to nourish your brain.

2. Blueberries
Blueberries are packed with antioxidants and flavonoids that protect the brain from oxidative stress and inflammation — two major causes of memory loss. Regular consumption of berries may improve learning, delay brain aging, and enhance coordination. Add them to your morning oatmeal or smoothies for a sweet, brain-boosting start.
3. Leafy Green Vegetables (Spinach, Kale, Broccoli)
Leafy greens are loaded with vitamins K, E, and folate, which are crucial for brain health. These nutrients reduce inflammation and support proper nerve function. Eating one serving of greens daily may slow cognitive decline and improve focus. Include spinach salads or steamed broccoli in your meals regularly.

4. Nuts and Seeds
Walnuts, almonds, and sunflower seeds are excellent sources of vitamin E and healthy fats. Vitamin E acts as a strong antioxidant that protects brain cells from damage. Research shows that people with higher vitamin E intake have a lower risk of cognitive decline. Snack on a handful of nuts daily to keep your brain sharp.
5. Olive Oil
Extra virgin olive oil is a cornerstone of the Mediterranean diet, known for its powerful anti-inflammatory properties. It contains polyphenols that may reduce the formation of harmful brain plaques linked to Alzheimer’s disease. Use olive oil for cooking or as a salad dressing to support both heart and brain health.

Bonus Tip: Stay Hydrated and Active
Food alone isn’t enough — combine a healthy diet with regular exercise, mental stimulation, and sufficient hydration. Drinking water and staying physically active improve blood flow to the brain, which helps preserve memory and focus over time.

Protecting your brain starts in your kitchen. By including these five dementia-fighting foods — fatty fish, blueberries, leafy greens, nuts, and olive oil — you can strengthen your memory, boost concentration, and reduce the risk of cognitive decline.
