Diet has a significant impact on mental health. Each ingredient has a unique role in creating a harmonious composition of health and well-being. The right food choices have a direct impact on clarity and mental peace. What you eat affects your mood, cognitive abilities, and risk of developing mental health conditions. Studies have shown that a diet consisting of fruits, vegetables, whole grains, and healthy fats improves mood, reduces stress and anxiety, and protects against cognitive decline. On the other hand, a diet composed mainly of processed foods, sugar, and unhealthy fats has been linked to poor mental health and a higher risk of developing mood disorders. It is important to see the link between diet and mental health and to make informed food choices that support your overall well-being.

The Interplay of Neurotransmitters and Hormones

The connection between diet and mental health is complex and multi-faceted. Diet affects mental health on a chemical level by influencing the levels and balance of neurotransmitters and hormones in the brain. Neurotransmitters, such as serotonin, dopamine, and norepinephrine, play a crucial role in regulating mood, attention, and emotional well-being. Hormones, such as cortisol and insulin, also have a significant impact on mood and cognitive function.

Fruits, vegetables, healthy fats, and whole grains significantly reduce inflammation, support healthy insulin function, and provide the brain with the nutrients it requires to produce and balance neurotransmitters and hormones. In contrast, a diet of processed foods, sugar, and unhealthy fats can cause inflammation, oxidative stress, and insulin resistance, disrupting the delicate balance of neurotransmitters and hormones in the brain.

A Holistic Approach to Health 

A healthy diet is one of the key factors of a holistic approach to health. This approach considers the interplay between physical, emotional, and environmental factors that impact a person’s well-being. It recognizes that mental health is not just the lack of mental illness but a state of balance and happiness that can be achieved through a combination of lifestyle choices, including a nutritious diet, regular exercise, stress management techniques, and social support. This way, individuals can create a healthy, balanced lifestyle that promotes a sound mind and body.

Foods that Boost Mental Health

Several ingredients and components provide mental and emotional balance, creating a harmony that lifts you from the inside out.

Salmon and Other Fatty Fish

Salmon has a high content of omega-3 fatty acids, which improve mood, reduce symptoms of depression and anxiety, and boost cognitive function. They also help reduce inflammation in the brain, which is a risk factor for many mental health conditions. Eicosapentaenoic acid and docosahexaenoic acid (DHA), two omega-3 fatty acids found in salmon and fatty fish, are particularly beneficial for mental health. EPA has a direct anti-inflammatory effect on the brain and helps regulate neurotransmitter levels. At the same time, DHA is an important component of the brain’s cellular membranes and is involved in neurotransmitter signaling. Clinical trials suggest the key role of EPA treatment in cases of borderline personality disorder and that of combined therapy with omega-3 and omega-6 fatty acids for cases of ADHD. Some trials have also reported the importance of the supplementary use of omega-3 fatty acids in managing chronic depression and schizophrenia.

Salmon and fatty fish are also good sources of vitamins B12 and D, which are important for brain health and mood regulation.


Blueberries, strawberries, and blackberries are good for mental health due to their high level of antioxidants, vitamins, and minerals. Antioxidants, such as anthocyanins and polyphenols, help protect the brain from oxidative stress and inflammation, which can impair cognitive function and contribute to mental health problems such as depression and anxiety. A diet rich in berries is particularly important in improving cognitive function in older adults. 

Berries contain vitamin C, which is important for the production of serotonin, dopamine, and folate.

A study concluded that introducing a Mediterranean-style diet, which is high in fruits, vegetables, whole grains, and healthy fats, significantly improved mental health in subjects with depression.

Nuts and seeds 

Nuts and seeds contain essential nutrients, such as omega-3 fatty acids, magnesium, and vitamin E, which help reduce inflammation in the brain, improve mood and cognitive function, and protect against age-related decline. Additionally, nuts and seeds are high in protein which is integral to healthy brain function. They also regulate blood sugar levels, positively affecting mood and energy levels. 

Leafy greens

Leafy greens, like spinach, kale, and collard greens, contain various nutrients that can positively impact mental health. They are high in folate, vitamin B9, and vitamin K, reducing the risk of Alzheimer’s disease. Another important component of leafy greens is antioxidants, such as vitamin C and beta-carotene protect the brain from oxidative stress, which can cause brain cell damage. Purslane contains high levels of omega-3 fatty acids. 

Whole grains

Whole grains provide the brain with complex carbohydrates and fiber, which help regulate and maintain blood sugar levels, positively impacting mood and energy levels. They are also a rich reserve of magnesium, and B vitamins, such as thiamine and niacin, which are crucial for brain function and mental health. They also contain antioxidants, such as selenium and vitamin E, that help protect the brain from oxidative stress.

According to a systematic review in the British Journal of Psychiatry, individuals who follow a diet that is rich in whole grains, vegetables, fruits, and healthy fats have a lower risk of depression compared to those who have a diet of processed foods, sugar, and unhealthy fats.

Fermented foods

Foods like yogurt, kefir, kimchi, and sauerkraut are rich in serotonin and probiotics, which are beneficial bacteria that can improve gut health and, in turn, boost mental well-being.

The relationship between the gut and the CNS is based on a triad of:

  • Diet
  • Microbiome
  • Inflammation

Gut-brain axis 

The gut-brain axis refers to the link between the gut microbiome and the brain, and the health of the gut microbiome has been shown to impact mental health. Probiotics in fermented foods can help to improve the diversity and balance of the gut microbiome, which can, in turn, improve mental health.


Chronic low-grade inflammation has been linked to several mental health conditions, and probiotics have been shown to have anti-inflammatory effects.

Dark chocolate

Dark chocolate is rich in flavonoids, an antioxidant that improves mood, reduces stress, and improves cognitive function, including attention and reaction time. Dark chocolate also contains theobromine and phenylethylamine, both of which are involved in the regulation of mood. Furthermore, it reduces stress by lowering levels of the stress hormone cortisol.


A healthy diet plays a paramount role in maintaining good mental health. A large meta-analysis of multiple studies found that consuming a diet of fruits, vegetables, and whole grains was associated with a 35% lower risk of depression compared to a diet high in processed foods and sugar.

However, one should consider that while incorporating these foods into a balanced diet can have benefits, they should not be considered the sole solution for mental health issues. A balanced diet with various nutrient-dense foods in moderation is the best way to support mental health. It’s always preferred to consult with a healthcare professional for personalized advice on improving one’s diet for optimal mental health.
