Brain Health: Foods to Boost Cognitive Functions

Nov 24, 2023 | Health Matters

Did you know that your kitchen holds the secret to enhanced brain power? The foods you choose every day can do more than just satisfy your cravings—they can actively boost your brain! These simple and impactful dietary choices will transform your life, allowing you to live a life you love!


How Diet Influences Cognitive Function

Eating well does more than just satisfy hunger; it’s essential for your brain’s well-being. Though arguably small, your brain is a major energy consumer, using a significant portion of the nutrients you consume. 

It’s not just about energy, though. Your brain needs different components and nutrients from your food for effective processing. Your diet’s balance of macronutrients (carbohydrates, proteins, and fats) greatly influences neurotransmitter pathways. These pathways are essential for the brain’s communication with your body, affecting everything from your mood to memory and concentration.

Your gut health also plays a noteworthy role. The gut-brain axis is a two-way communication system where your gut health impacts brain function, and vice versa. A diet that promotes a healthy gut microbiome equates to positive effects on both mental clarity, sharpened focus, and emotional well-being.

Consistent blood sugar levels are also necessary for brain health. Highs and lows can lead to mood swings, fatigue, and impaired cognitive functions. A balanced diet helps to maintain steady blood sugar levels, ensuring a consistent supply of energy to the brain.

By making informed dietary choices, you can easily and mindfully support your entire health and well-being without worrying about prescription medications or degradation of your vitality! You have the power to positively influence your brain’s fitness and performance through mindful eating, and we’re here to support you in this journey!


The Role of Hydration and Brain Function

Did you know that your brain is made up of 75% water, making hydration a non-negotiable factor in maintaining cognitive functions! It’s surprising (but not too uncommon) to know how many of you are skipping water on a daily basis. You should be drinking half of your body weight in fluid ounces per day. 

Adequate hydration helps in maintaining the flow of nutrients and oxygen to your brain, which is essential for its functioning. It also ensures your system is able to remove toxins and waste products from your brain during sleep, maintaining sharp focus and clarity of thought.

Dehydration, even in small amounts, impacts your cognitive abilities. It can lead to difficulties in concentrating, memory lapses, and a decrease in decision-making skills.

Drinking enough water is a simple yet effective way to support your brain health. For every glass of water you have, think of it as a double whammy, quenching thirst and ensuring your brain has what it needs to function at its best! 


Top Nutrients for Brain Health

Taking your health seriously can sound overwhelming and time-consuming, but it becomes easy once you know the best nutrients to amplify your brain’s health! 

This nutritional strategy supports varied aspects of brain function, from processing speed to emotional balance. Below is a curated list of my top ten nutrients that play a pivotal role in maintaining and improving brain health:

Omega-3 Fatty Acids

Found in fish like salmon and nuts like walnuts, these essential fats are key to brain cell structure and function. DHA, a type of Omega-3, is a major component of the cerebral cortex, necessary for memory, language, and cognition. EPA, another form, helps reduce inflammation and supports mood regulation. Regular intake of Omega-3s assists in maintaining brain health, enhancing learning, and protecting cognitive abilities over time.


These compounds, abundant in berries, dark chocolate, and tea, will have your cognition soaring. Flavonoids are known for their antioxidant and anti-inflammatory effects. They promote healthy blood flow to the brain, enhancing cognitive functions and memory. Regular consumption of flavonoid-rich foods can aid in slowing the progression of age-related cognitive decline.

Vitamin E

Vitamin E can be found in many products and foods due to its outstanding benefits. It is primarily found in seeds, nuts, and leafy greens and is a powerful antioxidant that safeguards our brain cells from oxidative stress and damage. This protection helps maintain our cognitive functions as you age, supporting memory retention and overall brain health.

Vitamin K

Present in leafy greens such as kale and spinach, Vitamin K is a nutrient you don’t want to miss. It aids in creating specific lipids that are critical to the brain’s structure and maintenance. Adequate Vitamin K intake is linked to improved memory performance and neuroprotective effects, particularly in aging brains.

Vitamin B12

Found primarily in animal products and fortified foods, Vitamin B12 is important for nerve health and cognitive function. It aids in producing myelin, which coats and protects nerve fibers, facilitating efficient signal transmission in the brain. Adequate B12 levels are associated with better memory recall and attention, as well as helping to prevent brain atrophy and loss of neurons.


Predominantly found in eggs, lean meats, and vegetables, Choline is a key nutrient for brain health. It is instrumental in synthesizing acetylcholine, a neurotransmitter for memory and learning processes. Adequate Choline intake is not only important for cognitive functions but also plays a role in mood regulation and the maintenance of healthy brain cell membranes.


This nutrient I am sure you have heard of! It is commonly found in red meat, beans, and cereals. Iron ensures oxygen transport to our brain, supporting overall brain energy metabolism. Adequate Iron levels are particularly important in women and children who tend to have lower levels. It’s great for supporting concentration, learning ability, and the development of cognitive skills. Iron deficiency can lead to impaired cognitive function and developmental delays, highlighting its importance in a balanced diet.


Get eating your nuts, whole grains, and avocados! Magnesium supports the biochemical reactions in the brain, including those that regulate neurotransmitter release. This regulation maintains cognitive functions such as memory and learning. Additionally, Magnesium plays a role in mood regulation, helping to alleviate stress and anxiety, which can impact cognitive clarity and focus.


Present in meat, nuts, and dairy, it’s an essential mineral for nerve signaling and cognitive stability. It regulates communication between neurons in the brain for learning and memory processes. Zinc also helps maintain the structure of proteins and cell membranes, protecting neurons from damage. Its role in synaptic plasticity – the ability to strengthen or weaken over time – is fundamental for cognitive development.


These compounds, plentiful in fruits and vegetables, particularly in blueberries, spinach, and kale, protect brain cells from oxidative stress and inflammation, factors that can contribute to cognitive decline. They help neutralize harmful free radicals, thereby reducing cellular damage. Regular intake of antioxidant-rich foods is linked to enhanced memory, better problem-solving abilities, and a lower risk of neurodegenerative diseases.

Adopting a diet rich in these nutrients represents a proactive approach to enhancing not only your physical well-being but your mental health, too! Our aim is to help you integrate these elements into your lifestyle for an easy way to enrich your life one bite at a time!


Practical Tips for Incorporating Brain Foods into Daily Meals

Adapting your diet to include brain-boosting foods can be easier and more enjoyable than you might think. It’s all about making small, manageable changes to your everyday meals. Here are five practical tips to help you seamlessly integrate these nutritious foods into your daily routine:
