19 Brain-Boosting Foods to Fight Alzheimer’s

Do you know your diet could be your greatest ally in fighting Alzheimer’s? Recent data shows that around 6.9 million Americans have Alzheimer’s, and this number is only expected to increase to 13 million by 2050. 

In Alzheimer’s, the neurons (cells in the brain) that are affected first are in charge of memory, language, and thinking, causing early issues in these areas. Interestingly, the brain changes behind these symptoms can start up to 20 years before anyone notices something’s off. This considerable time gap indicates why it’s essential to look after our brain health with a good diet and lifestyle before any symptoms appear.

In fact, the MIND diet, which is a mix of the Mediterranean and DASH diets, has been associated with a reduced risk of Alzheimer’s disease. Here are 19 brain-boosting foods to keep cognitive decline at bay and protect your lovely memories and quality of life. 

1. Leafy Greens

Leafy greens like spinach, kale, and collard greens top the list of brain-boosting foods. These veggies contain vitamin K, lutein, folate, and beta-carotene. These nutrients are your brain’s best friends. They help protect your brain cells from damage and reduce the risk of brain diseases like Alzheimer’s.

According to Research by Rush University in Chicago, adding these leafy greens into your diet can significantly slow cognitive decline. Plus, they’re easy to add to meals, whether in a salad, smoothie, or side dish. 

2. Beans

Beans are superfoods not only for your body but for your brain as well. Regular consumption of beans can even lower your chances of brain diseases like Alzheimer’s and is highly recommended as part of the MIND diet. 

Beans are rich in fiber and protein and help maintain a stable glucose level in the blood, which is essential for optimal brain function. They also contain a plentiful amount of antioxidants and essential B vitamins that help keep your brain healthy by fighting inflammation and oxidative stress, two factors that cause a drop in your cognitive abilities.  

Not only that, the slow-burning carbs in beans provide a steady energy source for the brain, keeping it fueled for longer periods and improving mental functions. Additionally, beans are loaded with magnesium, which is vital for brain messaging. Magnesium helps with memory and learning by improving the communication between brain cells. 

Add beans to salads and main dishes, or turn them into a yummy side dish.

3. Olive Oil

People who regularly use olive oil, such as in cooking or on salads, have a lower risk of developing brain problems as they age. 

Extra-virgin olive oil is particularly beneficial for our brains because of its healthy fats and polyphenols. These components are known for their unique anti-inflammatory and antioxidant properties, which are essential for boosting brain power. 

Research suggests that polyphenols can help to clear the toxins associated with Alzheimer’s disease from the brain. Plus, the good fats in olive oil help keep your brain cells in the best shape, which means better thinking and less chance of memory loss!

4. Berries

Berries, mainly blueberries, strawberries, and blackberries, are rich in antioxidants such as flavonoids. These small but mighty fruits help negate the effects of oxidative stress and inflammation in the brain. 

Studies have suggested that the antioxidants in berries can improve communication between brain cells and promote cell survival, enhancing memory and motor function. 

Including berries in your diet can be as simple as adding them to your morning cereal, blending them into smoothies, or munching on them throughout the day. Their versatility and health benefits make berries a crucial part of the MIND diet and a tasty solution for maintaining brain function.

5. Nuts

Nuts are a fantastic nutrient powerhouse and excellent for boosting brain health. Almonds, walnuts, and hazelnuts contain high levels of Vitamin E, an antioxidant known for shielding cell membranes from oxidative stress and slowing down the cognitive decline related to aging and diseases like Alzheimer’s.

Walnuts go a step further with omega-3 fatty acids, specifically alpha-linolenic acid (ALA), linked to improved brain health and a reduced risk of brain diseases. 

Eating a handful of nuts daily is recommended to support your cognitive function and overall health.

6. Whole Grains

Whole grains, such as oats, brown rice, barley, and whole wheat, provide a stable energy supply to our brains throughout the day. This continuous energy source helps boost concentration and focus, allowing the brain to perform at its best.

In addition, whole grains contain essential B vitamins, including B6, B12, and folic acid, which help reduce levels of homocysteine in the blood. High levels of homocysteine are linked with an increased risk of cognitive decline and Alzheimer’s disease. 

By keeping these levels in check, whole grains can help protect the brain from damage and promote overall mental well-being.

7. Oily Fish

Oily fish like salmon, mackerel, and sardines are loaded with omega-3 fatty acids, especially EPA (eicosapentaenoic acid) and DHA (docosahexaenoic acid), directly linked to brain health. These fatty acids are essential for keeping brain cell walls healthy, helping cells communicate, and creating new brain cells. 

Moreover, diets rich in omega-3s from oily fish can improve mood and reduce the risk of depression. 

Eating oily fish at least three times a week can provide these necessary nutrients, enhancing brain health and longevity.

8. Poultry

Poultry, including chicken and turkey, is a fantastic source of lean protein. It offers a lower-fat alternative to red meat and is crucial for brain health.

Poultry contains vitamin B6 and niacin, which are necessary for producing serotonin and dopamine, neurotransmitters (hormones) that regulate mood and cognitive functions such as memory and thinking. Chicken and turkey are also packed with choline, another essential nutrient for developing and maintaining healthy brain cells, further boosting cognitive functions.

Add poultry to your diet a few times a week, and you’ll have lower stress levels and improved mental health. It’s all thanks to those hormones that play a significant role in keeping our emotions balanced and our minds clear.

9. Wine

Drinking some wine, especially red wine, might benefit your brain. Red wine contains antioxidants like resveratrol and flavonoids. Resveratrol is especially interesting because it can improve blood flow to the brain, which might boost brain health and cognitive functions. It is a magic ingredient in grape skins that protects brain cells from damage. 

A study suggests that moderate wine drinkers had lower risks of developing Alzheimer’s disease compared to non-drinkers. But remember, the key is moderation, typically defined as one glass per day for women and up to two glasses per day for men, as part of a balanced diet and lifestyle. 

10. Citrus Fruits

Fruits play a crucial role in maintaining brain health thanks to their high levels of antioxidants, vitamins, and minerals. In addition to berries, which we discussed earlier, citrus fruits, like oranges and lemons, are another excellent choice for brain health. 

They are high in vitamin C, which is known to fight off oxidative stress. This stress can damage brain cells and affect the ability to think clearly or recall information. 

Regular consumption of vitamin C-rich fruits can support cognitive health by defending the brain against such damage.

11. Vegetables

In addition to leafy greens, cruciferous vegetables like broccoli, Brussels sprouts, bell peppers, and carrots are rich in antioxidants and carotenoids, powerful brain protectors. These compounds have been linked to improved memory, focus, and overall cognitive performance. 

Additionally, vegetables are low in calories and fiber, making them perfect for maintaining a healthy weight and reducing the risk of chronic diseases such as diabetes and heart disease. 

By incorporating a variety of colorful vegetables into your diet, you can support both physical and cognitive health for optimal well-being. 

12. Seeds

Seeds are tiny but rich in nutrition and can do wonders for brain health. Flaxseeds, chia seeds, and hemp seeds are essential because they contain high amounts of alpha-linolenic acid (ALA), omega-3 fatty acid. 

Omega-3s are crucial for brain health. ALA, in particular, is linked to a reduced risk of age-related mental decline and has been shown to improve memory and cognitive performance.

Pumpkin seeds deserve special mention. These little powerhouses contain brain-boosting nutrients like zinc, magnesium, iron, and copper. Zinc keeps your nerve signals on point, magnesium helps with learning and memory, iron fights off brain fog, and copper controls nerve signals.

In addition to omega-3 fatty acids, sunflower seeds are rich in vitamin E, an antioxidant believed to protect the brain against oxidative stress and age-related decline.

13. Herbs and Spices

Herbs and spices play a significant role in maintaining and enhancing brain health. Turmeric, for instance, is famous for its compound curcumin, which is packed with anti-inflammatory and antioxidant properties.

Research suggests that curcumin may help improve symptoms of Alzheimer’s disease by reducing inflammation and oxidation in the brain. 

Cinnamon is another star spice. It improves cognitive processing and fights neurological disorders. Again, cinnamon’s unique compounds can protect brain cells against oxidative stress, reduce inflammation, and improve motor function. 

14. Dark Chocolate

Research suggests dark chocolate has neuroprotective effects. Regular consumption helps lower the risk of brain diseases by keeping neurons alive, encouraging new brain cells to grow, and boosting brain flexibility.  This is partly due to increased blood flow and flavonoids’ anti-inflammatory effects. 

Additionally, dark chocolate has been linked to the production of endorphins, the body’s natural “feel-good” chemicals. Endorphins can improve mood and decrease stress levels, indirectly benefiting brain health.

Choosing dark chocolate with a high cocoa content (70% or higher) is crucial to reap these benefits as it contains less sugar and more beneficial compounds. However, moderate your intake, as dark chocolate is still calorie-dense. Incorporating small amounts into your diet can be an enjoyable and effective way to support cognitive function and overall brain health.

15. Eggs

Eggs are packed with ingredients that are great for the brain, such as vitamins B6 and B12, folate, and choline. Choline is particularly important as it plays a significant role in brain development and function. The body uses it to produce acetylcholine, a neurotransmitter that helps regulate mood and memory.

Studies suggest that higher intakes of choline can improve memory and cognitive processing, making eggs an essential part of your diet for maintaining mental sharpness.

Eggs also contain a lot of Vitamin B12, which keeps nerve fibers and brain cells healthy. B12 deficiency can cause memory problems and nerve damage. Folate, another brain booster found in eggs, works with B12 to keep the mind active.

16. Cheese

Cheese also offers promising benefits for brain health. This dairy product is rich in essential nutrients like calcium, protein, and vitamins A and B-12, which help maintain neurological function and overall brain health. Additionally, certain aged cheeses are a source of tyramine, an amino acid that enhances alertness and memory.

Studies show eating cheese regularly can help prevent age-related cognitive decline as part of a balanced diet. 

Although the saturated fats in cheese were once argued as bad, new research indicates that these fats are essential for brain cell membranes, helping cell communication and function. 

17. Yogurt

Yogurt, known for being rich in probiotics, is critical in maintaining brain health through the gut-brain axis, an essential pathway through which the gut and brain communicate. Probiotics in yogurt are good bacteria that keep the gut healthy, indirectly helping you feel less stressed, improve your mood, and help your brain work better.

A healthy gut can affect brain chemicals like serotonin, which makes you happy and reduces inflammation. Lack of these chemicals is linked to brain diseases like Alzheimer’s and Parkinson’s.

Regular yogurt consumption can also help absorb essential nutrients crucial for brain health, such as B vitamins, calcium, and magnesium. These nutrients are vital for brain development, neurotransmitter function, and protection against oxidative stress. 

18. Coffee

The primary active ingredient in coffee, caffeine, is a powerful stimulant that can enhance brain function by increasing alertness, attention, and concentration. This makes coffee a popular choice for improving mental performance, especially during tasks that require complete focus.

Beyond its direct stimulating effects, long-term coffee consumption has been linked with a reduced risk of neurological diseases, including Parkinson’s and Alzheimer’s. Studies suggest that caffeine may offer protective benefits by controlling the accumulation of toxic proteins linked to neurodegeneration. 

19. Tea

Tea, mainly green tea, is another beverage known for its brain-boosting abilities. It contains antioxidants that protect brain cells and can improve memory, focus, and the speed at which you process information.

Green tea also contains a unique amino acid, L-theanine, which can cross the blood-brain barrier and calm the brain. This ingredient works well with caffeine to make you more focused and in a better mood without feeling shaky, like you might with coffee. 

Drinking green tea regularly could also lower your chances of getting brain diseases like Alzheimer’s because it fights inflammation and protects brain cells.
