Food for brain health – brain boosting foods

The brain is a vital organ that plays a crucial role in our overall well-being. It controls our thoughts, emotions, memories, and bodily functions. Just like any other organ in our body, the brain requires proper nutrition to function optimally. In this article, we will explore the importance of food for brain health, the role of nutrition in supporting brain function, and the best brain-boosting foods to enhance brain health. So, let’s dive in!

Understanding brain health

Importance of brain health

The brain is responsible for processing information, regulating bodily functions, and controlling our behaviour. Maintaining brain health is essential for cognitive function, memory retention, and overall mental well-being. As we age, it becomes even more crucial to prioritise brain health to reduce the risk of age-related cognitive decline and neurodegenerative diseases such as Alzheimer’s and dementia.

Factors affecting brain health

Several factors can influence brain health. These include genetics, lifestyle choices, environmental factors, and overall health conditions. While we can’t control our genetics, we have the power to make positive changes in our lifestyle and diet to support our brain’s health and longevity.

Role of food for brain health

Nutrition plays a vital role in maintaining optimal brain health. The brain requires a steady supply of nutrients to function efficiently and repair any damage. Food for brain health can protect the brain from oxidative stress, inflammation, and other forms of cellular damage. By eating a nutrient-rich diet, we can provide our brains with the essential building blocks it needs to stay healthy.

In fact, evidence suggests that what is good for your heart health is also good for your brain health.

Key nutrients for brain health

Certain nutrients are particularly beneficial for brain health due to their specific functions and protective properties. Including these nutrients in your diet can help support brain function and reduce the risk of cognitive decline. Let’s explore some of these key brain boosting foods.

Omega-3 fatty acids

Omega-3 fatty acids, especially EPA and DHA, are crucial for brain health. These fatty acids are found in high amounts in fatty fish like salmon, mackerel, and sardines. Omega-3s play a role in brain development and function, and they have been linked to improved cognitive performance and a reduced risk of neurodegenerative diseases.


Antioxidants are compounds that help protect the brain from oxidative stress and inflammation. Berries, particularly blueberries, are rich in antioxidants and have been shown to improve memory and cognitive function. Other antioxidant-rich brain boosting foods include dark chocolate, spinach, and colourful fruits and vegetables.

B Vitamins

B vitamins, including folate, B6, and B12, are essential for brain health. They are involved in the production of neurotransmitters, which transmit signals between brain cells. Foods rich in B vitamins include leafy greens, legumes, eggs, and fortified cereals.

Vitamin D

Vitamin D deficiency has been linked to cognitive impairment and an increased risk of neurodegenerative diseases. Sunlight is the best source of vitamin D, but it can also be obtained from fatty fish, fortified dairy products, and supplements.


Magnesium is an essential mineral that plays a role in neurotransmitter function and has been associated with improved memory and learning abilities. Magnesium-rich food for brain health include almonds, spinach, avocados, and whole grains.


Zinc is involved in numerous processes in the brain, including neurotransmitter synthesis and regulation of synaptic plasticity. Brain boosting foods rich in zinc include oysters, beef, pumpkin seeds, and fortified cereals.


Iron is necessary for oxygen transport to the brain and the production of neurotransmitters. Good sources of iron include lean meats, legumes, fortified cereals, and leafy greens.


Choline is a nutrient that supports brain health and is a precursor to the neurotransmitter acetylcholine. Eggs, liver, and soybeans are excellent sources of choline.

Food for brain health

Now that we understand the key nutrients for brain health, let’s explore the specific brain boosting foods that can provide these nutrients and boost brain function.

Fatty fish

Fatty fish such as salmon, trout, and sardines are rich in omega-3 fatty acids. These fatty acids are essential for brain health, as they support the structure of brain cells and promote communication between brain cells. Regular consumption of fatty fish has been associated with a reduced risk of cognitive decline and improved memory.

As delicious as salmon can be, it is usually farmed in unhealthy and unsustainable conditions. The pick of the fish on this list is probably sardines, but that can be a hard sell. Here are some recipes that might whet your appetite for sardines.

Meditteranean sardine salad – – looks like a lovely quick and tasty lunch!

Sardine patties – – would be a great dinner with a salad, or a side of sweet potato fries

If you don’t mind carbs – try this sardine puttanesca – – you might want to nix the breadcrumbs!

Sardine fishcakes – – always a good idea if you are strapped for cash this week. Would be delicious with brown rice and accoutrements and/or a green leafy salad.


Blueberries are packed with antioxidants that help protect the brain from oxidative stress and reduce inflammation. Studies have shown that regular blueberry consumption can improve memory and delay age-related cognitive decline. Add a handful of blueberries to your breakfast or enjoy them as a healthy snack.

Unless you are eating steel-cut oats for breakfast, I wouldn’t recommend having cereal for breakfast, which removes the opportunity for blueberries with breakfast. However, they can be a great topping on Greek yoghurt for a snack. (They can be expensive in winter months though!)


Turmeric contains a compound called curcumin, which has potent anti-inflammatory and antioxidant properties. Curcumin can cross the blood-brain barrier and has been shown to have neuroprotective effects. Incorporate turmeric into your cooking or try adding a turmeric supplement to your daily routine.

The best way I have found to consume turmeric is in a golden milk latte. This Amazonia Golden Latte is easy to prepare, full of goodness and delicious! Find it in Australia

Or a similar product in the USA – 


Broccoli is rich in antioxidants and brain-healthy nutrients like vitamin K, vitamin C, and folate. These nutrients help protect the brain from damage and support cognitive function. Include broccoli in your salads, stir-fries, or steamed vegetable dishes.

Here is a delicious broccoli soup and a wonderful broccoli salad to make for lunch in winter/summer months:

Cream of broccoli soup – – I made it today. It is truly superb.

Favourite broccoli salad recipe – – still tasty without cheese!

Pumpkin seeds

Pumpkin seeds are an excellent source of magnesium, iron, zinc, and antioxidants. These nutrients contribute to brain health by supporting neurotransmitter function and reducing oxidative stress. Enjoy a handful of pumpkin seeds as a snack or sprinkle them over salads and yogurt.

Dark chocolate

Dark chocolate contains flavonoids, antioxidants that improve blood flow to the brain and enhance cognitive function. It also contains small amounts of caffeine, which can improve alertness. Choose dark chocolate with at least 70% cocoa content for maximum benefits. It is one of the best brain boosting foods out there, and not least because it is so delicious!

I tend to make hot chocolate with pure cacao powder instead of eating chocolate for dessert.  A teaspoon of cacao in a cup of hot oat milk – (dissolve the powder in a little hot milk first, then add the rest) does everything for my brain that a square of dark chocolate would, but without the risk of overindulging (and eating the whole block).


Oranges and other citrus fruits are high in vitamin C, which is essential for preventing mental decline. Vitamin C is a powerful antioxidant that helps protect brain cells from damage and supports the production of neurotransmitters. Enjoy oranges as a refreshing snack or squeeze fresh orange juice.

Green tea

Green tea is rich in antioxidants and contains an amino acid called L-theanine, which can improve focus and promote relaxation. The combination of caffeine and L-theanine in green tea provides a gentle energy boost without the jitters. Add a cup of green tea or even better, a cup of matcha to your daily routine and reap the benefits.

If you really want to take green tea consumption to another level you could try organic matcha powder. It is also lovely in a cup of hot oat milk (just be sure to dissolve the powder in a little hot milk first, before adding the rest, so that the powder dissolves and doesn’t form clumps). It can be an acquired taste, but you can add maple syrup if you would prefer it to be a little sweeter.

Matcha is like green tea, but on steroids, and it has so many positive benefits for your health. It is one of the best brain boosting foods you can find.

Nuts and seeds

Nuts and seeds, such as almonds, walnuts, and flaxseeds, are packed with nutrients that support brain health. They contain a combination of omega-3 fatty acids, antioxidants, vitamin E, and other beneficial compounds. Snack on a handful of nuts or sprinkle seeds over salads and oatmeal.

Whole grains

Whole grains, such as oats, quinoa, and brown rice, provide a steady release of glucose to the brain. This helps improve concentration and cognitive function. Choose whole-grain bread, pasta, and cereals to fuel your brain throughout the day.

The Mediterranean Diet and brain health

The Mediterranean diet is a popular eating pattern known for its numerous health benefits, including brain health. Let’s take a closer look at how the Mediterranean diet can support your brain.

Overview of the Mediterranean Diet

The Mediterranean diet emphasizes whole, unprocessed foods, with an abundance of fruits, vegetables, whole grains, legumes, nuts, seeds, and olive oil. It also includes moderate amounts of fish, poultry, and dairy products, while limiting red meat and sugary foods.

Benefits of the Mediterranean Diet for brain health

The Mediterranean diet is rich in nutrients and food for brain health, including omega-3 fatty acids, antioxidants, and vitamins. It has been associated with a reduced risk of cognitive decline, improved memory and focus, and a lower incidence of neurodegenerative diseases.

Sample Mediterranean diet meal plan

Here’s a sample meal plan to give you an idea of how to incorporate the Mediterranean diet into your daily routine:

  • Breakfast: Greek yogurt topped with berries and a sprinkle of nuts, or an omelette made from one organic egg, some chopped olives, onion, mushrooms, spinach and organic tomato on whole grain toast with olive oil and a cup of green tea or organic coffee.
  • Lunch: Mediterranean salad with mixed greens, cherry tomatoes, cucumber, olives, feta cheese, and grilled chicken. Dress with olive oil and lemon juice.
  • Snack: A handful of almonds and an orange.
  • Dinner: Baked salmon with lemon and herbs, served with quinoa and roasted vegetables. Enjoy a glass of red wine in moderation.
  • Dessert: A square of dark chocolate or a cup of hot chocolate made from cacao powder.

Hydration and brain function

Proper hydration is essential for overall health, and it also plays a significant role in brain function. Let’s explore the importance of staying hydrated for optimal brain health.

Importance of hydration

The brain is made up of about 75% water, and even mild dehydration can affect cognitive function, mood, and concentration. When you’re dehydrated, your brain cells shrink, leading to slower processing speeds and reduced mental clarity.

Effects of dehydration on the brain

Dehydration can cause symptoms such as fatigue, headaches, dizziness, and difficulty concentrating. Studies have shown that even mild dehydration can impair memory, attention, and other cognitive functions.

Tips for staying hydrated

To stay properly hydrated and support your brain function, follow these tips:

  • Drink water throughout the day, aiming for at least eight glasses (2 litres) of water.
  • Limit your consumption of sugary drinks and caffeinated beverages, as they can contribute to dehydration.
  • Eat water-rich foods like watermelon, cucumbers, and soups.
  • Keep a water bottle with you at all times to remind yourself to drink.
  • Listen to your body’s thirst cues and drink whenever you feel thirsty.

The Gut-Brain connection

Research has shown that there is a strong connection between the gut and the brain. The health of our gut microbiota, the trillions of bacteria residing in our digestive system, can influence brain health and function. Let’s explore this fascinating connection.

Gut microbiota and brain health

The gut microbiota plays a crucial role in regulating brain function and mental well-being. The gut and the brain communicate through a complex network called the gut-brain axis. The balance of beneficial and harmful bacteria in the gut can impact mood, cognition, and behaviour.

Foods that promote a healthy gut

Consuming a diet rich in fibre and fermented foods can support a healthy gut microbiota. Include the following food for brain health in your diet to promote a healthy gut:

  • Fibre-rich foods: Whole grains, fruits, vegetables, legumes, and nuts provide fibre, which nourishes beneficial gut bacteria.
  • Fermented foods: Yogurt, kefir, sauerkraut, kimchi, and kombucha contain probiotics, which are beneficial bacteria that support gut health.

Probiotics and prebiotics

Probiotics are live bacteria that provide health benefits when consumed. They can be found in certain foods like yogurt or taken as supplements. Prebiotics, on the other hand, are non-digestible fibres that serve as food for beneficial gut bacteria. They can be obtained from certain fruits, vegetables, and whole grains (bananas, onions and leeks for example). Consuming probiotic and prebiotic-rich foods can help maintain a healthy balance of gut bacteria and support brain health.

Lifestyle factors for brain health

In addition to nutrition, several lifestyle factors play a significant role in maintaining optimal brain health. Let’s explore these factors and how they can support your cognitive function.

Physical exercise

Regular physical exercise has been linked to improved brain health and cognitive function. Exercise increases blood flow to the brain, stimulates the release of growth factors that promote the formation of new brain cells, and reduces the risk of chronic conditions that can negatively impact brain health. Aim for at least 150 minutes of moderate-intensity exercise or 75 minutes of vigorous exercise each week.

Mental stimulation

Engaging in mentally stimulating activities can help keep your brain sharp and reduce the risk of cognitive decline. Read books, solve puzzles, play brain-training games, learn a musical instrument, or engage in activities that challenge your cognitive abilities.

Quality sleep

A good night’s sleep is essential for brain health and cognitive function. During sleep, the brain consolidates memories, repairs cells, and flushes out toxins. Aim for 7-9 hours of quality sleep each night by establishing a relaxing bedtime routine and creating a sleep-friendly environment.

Stress management

Chronic stress can have detrimental effects on brain health and cognition. Find healthy ways to manage stress, such as practising mindfulness meditation, deep breathing exercises, yoga, or engaging in hobbies and activities that bring you joy and relaxation.


Prioritizing brain health is crucial for maintaining cognitive function, memory retention, and overall well-being. By understanding the importance of nutrition, including key nutrients in the choice of food for brain health in our diet, and adopting a brain-healthy lifestyle, we can support our brain’s health and reduce the risk of cognitive decline. Remember to incorporate foods like fatty fish, blueberries, turmeric, and dark chocolate, and follow the principles of the Mediterranean diet. Stay hydrated, nurture a healthy gut, and embrace physical exercise, mental stimulation, quality sleep, and stress management for optimal brain health.
