Your brain is one of the most energy demanding organs in your body. It controls movement, memory, learning, emotions, concentration and countless other essential functions. While factors such as age, genetics, sleep, physical activity and stress can influence brain health, nutrition also plays an important role.

Choosing the right foods that support brain health can help provide the nutrients your brain needs to function normally. A balanced diet rich in vegetables, fruits, whole grains, fish, nuts, seeds, legumes and healthy fats can provide vitamins, minerals, antioxidants and other nutrients associated with overall brain and cognitive health.

There is no single “superfood” that can guarantee better memory or prevent cognitive decline. Instead, long term dietary patterns matter most. A varied and nutrient rich diet can support the body’s overall health which in turn provides a foundation for healthy brain function.

In this guide, we’ll explore the best brain healthy foods, important nutrients for cognitive function, foods to limit and practical ways to build a diet that supports brain wellness.

What is Brain Health?

Brain health refers to the ability of the brain to perform important functions throughout life. These functions include:

• Memory
• Learning
• Attention
• Concentration
• Problem solving
• Communication
• Emotional regulation
• Movement and coordination

Brain health can be influenced by many factors. Nutrition is one piece of the picture, along with physical activity, sleep, social connection, stress management and overall health.

A nutritious diet cannot guarantee that someone will avoid cognitive problems but consistently eating a balanced diet can help provide essential nutrients needed for normal brain function.

15 Foods That Support Brain Health and Cognitive Function

1. Fatty Fish

Fatty fish are among the most commonly recommended foods for a brain supportive diet.

Salmon, sardines, trout, mackerel, herring and similar fish provide omega-3 fatty acids including EPA and DHA. DHA is an important structural component of cell membranes including those found in the brain.

Fatty fish also provide high quality protein, vitamin B12, vitamin D, selenium and other nutrients.

Try including fish in meals such as:

• Grilled salmon with vegetables
• Sardine salad
• Baked trout with brown rice
• Mackerel with roasted vegetables

For people who eat seafood, regularly including a variety of fish can contribute to a nutrient rich eating pattern.

2. Blueberries

Blueberries are rich in vitamins, fiber and naturally occurring plant compounds called flavonoids.

Their deep color comes partly from compounds known as anthocyanins.

Berries can be an easy addition to a brain conscious diet because they are versatile and require little preparation.

Add blueberries to:

• Oatmeal
• Greek yogurt
• Smoothies
• Whole grain cereal
• Fruit salads

Other berries, including strawberries, blackberries and raspberries can provide additional variety.

3. Leafy Green Vegetables

Spinach, kale, broccoli leaves, collard greens and other leafy vegetables provide a wide range of nutrients.

They can provide:

• Folate
• Vitamin K
• Vitamin C
• Vitamin A
• Magnesium
• Carotenoids
• Dietary fiber

These vegetables can be eaten raw in salads or cooked in soups, curries, stir fries and omelets.

Try adding leafy greens to at least one meal each day as part of a broader plant rich diet.

4. Walnuts

Walnuts provide healthy unsaturated fats, fiber, protein, magnesium and plant based omega-3 fatty acids.

They can be an easy snack or a topping for other nutrient rich foods.

Try adding a small handful of walnuts to:
