Jan 18, 2024 | Health Matters, Learn to Eat Clean and Healthy

Does your mind feel like it’s running slowly? Imagine reaching peak mental performance with just a few changes to your next meal! We’re here to show you how specific foods can transform your mental stamina and cognitive function, turning that mental fatigue into a thing of the past.


Can Food Help Your Cognition?

The connection between your diet and cognitive performance is deeply intertwined. When you consume food, it’s broken down into nutrients that are absorbed into your bloodstream and carried to your brain. Once there, these nutrients play several integral roles throughout your body. They provide the energy your brain cells need to function effectively, forming the foundation for all cognitive activities. Glucose and fats (our brains are made up of 80% fats), for instance, are primary energy sources for the brain, influencing attention, memory, and learning.

But your food doesn’t just act as energy; certain nutrients are involved in synthesizing neurotransmitters, the brain’s chemical messengers. Neurotransmitters like serotonin, dopamine, and norepinephrine regulate mood, concentration, and alertness. They are directly influenced by the food you eat! A lack of essential nutrients can lead to a decline in the production of these neurotransmitters, affecting how your brain processes information.

Brain function is also heavily impacted by inflammation and oxidative stress. Nutrients that have anti-inflammatory and antioxidant properties help protect brain cells from damage and deterioration, which can affect cognitive function. This protection is key in maintaining brain health over time, especially as we age.

Have you heard of your gut-brain connection? This conceptualizes the evidence we have that what you eat directly affects your mind, and likewise, than your mental health (mind) directly affects your gut health. Understanding this can help you ensure you are staying at peak performance in both your mind and body. When you nurture your microbiome, you’re looking out for your cognition, and everything in between! Our physiology works together as one dynamic, impressive, system.

It’s safe to say, the foods you consume profoundly impact your brain’s ability to perform. They provide the necessary energy, support neurotransmitter synthesis, and protect against cellular damage, all essential for optimal mental performance. 


Can What You Eat Help With Your Emotions?

The food you eat is closely tied to your emotional regulation and stability. This is because the nutrients you consume foster a delicate balance of biochemical reactions and hormone release. 

As we covered, nutrients from food impact the synthesis and function of neurotransmitters. Some of these are responsible for mood regulation. Unlike direct energy sources for the brain, these nutrients subtly modify the brain’s environment, affecting how it responds to and processes emotional stimuli. This modification can either enhance or hinder the brain’s ability to manage emotions effectively.

Your diet choices influence hormonal balance, which is critical for emotional (and reproductive) health. Hormones related to stress, sleep, and pleasure are affected by dietary choices. The brain’s emotional processing centers require specific nutritional support to function optimally, highlighting the importance of diet in emotional well-being. 

What’s on your plate can even cause or relieve neuroinflammation. Chronic brain inflammation has been linked to mood disorders. Nutrients that have anti-inflammatory properties can help mitigate this, supporting healthier emotional responses.

By understanding the significance of mindful eating, you can ensure your diet supports your physical health, cognitive performance, and emotional health. 


Top 20 Foods to Eat for Mental Performance

If you want to boost your mental performance, start by adding these key ingredients into your meals whenever possible:

  1. Fatty Fish: Rich in omega-3 fatty acids, fatty fish like salmon and trout are incredible for brain health. Omega-3s aid in building brain and nerve cells, essential for learning and memory.
  2. Blueberries: Packed with antioxidants, blueberries can delay brain aging and improve memory. Antioxidants act against oxidative stress and inflammation, conditions that can contribute to brain aging and neurodegenerative diseases.
  3. Turmeric: This deep-yellow spice has curcumin, which can cross the blood-brain barrier and directly enter the brain to benefit cells. It’s a potent anti-inflammatory and antioxidant compound, boosting serotonin and dopamine.
  4. Broccoli: High in antioxidants and vitamin K, broccoli is excellent for brain health. Vitamin K enhances cognitive abilities and is essential for forming sphingolipids, a type of fat densely packed into brain cells.
  5. Pumpkin Seeds: Contain powerful antioxidants and a rich source of iron, zinc, magnesium, and copper. Each of these nutrients is important for brain health – for nerve signal control, brain cell production, and regulation of neurotransmitters.
  6. Dark Chocolate: Contains flavonoids and antioxidants. Flavonoids are brain-boosting compounds, enhancing memory and slowing down age-related mental decline.
  7. Nuts: Especially walnuts, are good sources of protein, healthy fats, and antioxidants. These nutrients can boost mood and protect against neurodegenerative diseases.
  8. Oranges: High in vitamin C, essential for preventing mental decline. Vitamin C is a powerful antioxidant that helps fight off the free radicals that can damage brain cells.
  9. Eggs: A great source of several nutrients tied to brain health, including vitamins B6 and B12, folate, and choline. Choline is used to create acetylcholine, a neurotransmitter that helps regulate mood and memory.
  10. Green Tea: As well as improving alertness, it can boost brain function. It contains L-theanine, which can increase the activity of the neurotransmitter GABA, reducing anxiety.
  11. Avocados: These fruits are full of monounsaturated fats, promoting healthy blood flow, which is essential for a healthy brain. Healthy fats also help keep blood pressure levels steady, which benefits brain health.
  12. Beets: Beets are known for their ability to increase blood flow to the brain, enhancing mental performance. The nitrates in beets help improve blood flow, which is required for optimal brain functioning.
  13. Seeds (Flaxseed and Chia seeds): Rich in alpha-linolenic acid, a type of omega-3 fatty acid, these seeds are important for brain function and reducing inflammation.
  14. Whole Grains: Foods like oatmeal, barley, and whole-grain breads provide a steady supply of energy (glucose) to the brain, which is paramount for maintaining concentration and cognitive functioning.
  15. Tomatoes: With powerful antioxidants like lycopene, tomatoes help protect against free radical damage to cells, which is a concern in the development of dementia, especially Alzheimer’s.
  16. Poultry or other Lean Proteins: Sources like chicken and turkey or other lean proteins have essential amino acids needed for neurotransmitter function. These proteins also contain B-vitamins, which aid in brain health and cognitive function.
  17. Leafy Greens: Vegetables such as kale and spinach are rich in folate and other essential vitamins, and contain antioxidants that are key in promoting brain health and new brain cell growth.
  18. Blackcurrants: High in vitamin C, known for its ability to increase mental agility, blackcurrants are excellent for cognitive function.
  19. Carrots: Carrots are a good source of luteolin, a compound that helps reduce age-related memory deficits and inflammation in the brain, thus aiding cognitive health.
