Brain health is important to consider at all ages and all stages of life. Every day, we’re learning more about the connections between brain health and the foods we eat. This powerful organ enables us to think, remember, feel, and move, and empowers every part of the body to do its job. The whole body benefits when we eat food that is good for the brain.
Foods that can support brain health
- Blueberries: Blueberries are a great food for a healthy brain. They have nutrients that support memory, decision-making, concentration and mood in kids. Plus, blueberries are high in antioxidants and their deep blue pigment, known as anthocyanins, are associated with a slower age-related decline in cognitive performance.
- Leafy Greens: Add leafy greens (think spinach, kale, arugula or Swiss chard) to your diet! Consumption of one serving of leafy greens was associated with slower cognitive decline in the Memory and Aging Project.
- Other vegetables: Consuming additional vegetables each day can further benefit brain health. Researchers suggest that vitamins K and E, lutein, beta-carotene, folate and nitrate – all found in a variety of vegetables – may play a primary role in slowing cognitive decline with aging.
- Legumes: Consumption of legumes, such as beans, peas and chickpeas, has been associated with reduced severity of dementia among older adults.
- Nuts: Nuts are a nutritious source of plant-based protein and unsaturated fat – and long-term nut consumption may also improve cognitive function and help reduce cognitive dysfunction, such as dementia.
- Olive Oil: Using olive oil as your primary cooking oil is a key component of the MIND Diet, which aims to reduce dementia and brain function decline.
- Whole Grains: The MIND Diet also suggests eating at least 3 servings of whole grains per day for optimal brain health. Whole grains, like oatmeal, brown rice and whole wheat pasta, are good sources of fiber and other essential nutrients.
- Eggs: Eggs are a nutrient-rich food providing a good or excellent source of eight essential nutrients, including choline, which helps support lifelong brain health including, thinking, mood and more.
- Seafood: Fish and shellfish are among the only foods naturally rich in the omega-3 oils EPA and DHA, which positively affect both brain and heart health.
How to include more brain foods into your diet
Including brain healthy foods in your diet can help support brain function, improve mood and reduce cognitive decline. So, here’s a plan for how to include more healthy brain foods in your daily eating patterns:
- Meal Planning: Planning out your meals for the entire week can help ensure that you’re eating lots of good-for-you foods – but thinking about a whole week of meals can be overwhelming. Give yourself a break and try to plan for just 3 days at a time. What do you have in the that you need to use? What dish can you make for dinner tomorrow that will provide leftovers for lunch the next day?
- Smart Shopping: Once you have your meal plan, shopping smart is easy! Review what you need for your planned meals, take stock of what you have in the fridge and pantry, and make a list of what you’re missing. Pro tip: organize your grocery list by the sections of the store (produce, dairy, bakery, middle aisles) to keep your time in the store efficient.
- Meal Prepping: When you get home from the store, wash and store your fruits and vegetables so that they’re ready to use. Rinse, dry and cut vegetables into sticks to have on hand for snacking. Boil some eggs so they’re ready to snack or chop into salads. Rinse and dry berries and store them in an airtight container with a paper towel.
