Correct your nutrition and supplement

Eating the right diet and digesting and absorbing the right nutrients can improve our mental health by reducing inflammation, aiding detoxification, balancing our blood sugar, balancing our hormones, improving our gut health, and providing the right building blocks to make the right hormones and neurotransmitters for better mental health.

There is increasing awareness that our current dietary patterns and lifestyles of processed foods and eating on the run, coupled with the environmental and social impacts of climate change, urbanisation, 24/7 technology, increasing noise, light, air, water and soil pollution, are all detrimental to our mental health.Logan, A. C., & Jacka, F. N. (2014). Nutritional psychiatry research: an emerging discipline and its intersection with global urbanization, environmental challenges and the evolutionary mismatch. Journal of physiological anthropology33(1), 22. [accessed 13th July 2020].

By returning to more traditional diets and nutrition patterns, and by making sure that we are obtaining optimal nutrients from better diets consumed in healthier emotional and physical environments, we can have a substantial positive impact on our mental health.

The single most important thing you can do to keep your brain functioning at its peak and prevent brain ageing […] you must be vigilant about what you put on your plate. It’s as simple as that. Nutrition is the most important tool for staying mentally and physically fit.Perlmutter, D. and Colman, C. (2004). The Better Brain Book. New York: Riverhead Books, p. 61.

See below for guidelines on how to correct your nutrition and supplement for better mental health.

In order to optimise digestion, nutrient absorption and blood sugar levels:

  • Eat at least three complete meals a day (containing the three main macronutrient groups – complex carbohydrates, proteins and fats) and do not skip meals (unless you are deliberately doing intermittent fasting, which can also be helpful to mental health). Read more about how to correct each of the three main macronutrient groups by clicking on the links below.
  • Eat while sitting down in a stress free environment and focus on chewing your food carefully and consciously (some say at least 30 times for each mouthfulMercola. (2015). Should You Really Chew Your Food 32 Times? [online] Mercola. Available at: [accessed 15 Nov. 2017].).
    • The stress hormone cortisol can increase if you eat on the run, work on your computer or mobile phone or have an argument while you eat. It slows down digestion and the release of digestive enzymes
    • Stress and increased cortisol levels can also increase gut permeability which can reduce nutrient absorption and cause inflammation over the long term
    • Stress is implicated in IBS and peptic ulcer diseaseVanuytsel, T., van Wanrooy, S., Vanheel, H., Vanormelingen, C., Verschueren, S., Houben, E., Salim Rasoel, S., Tóth, J., Holvoet, L., Farré, R., Van Oudenhove, L., Boeckxstaens, G., Verbeke, K. and Tack, J.

Available at: [accessed 18 Aug. 2017].

Avoid processed foods, and foods containing refined carbohydrates such as sugars and white flours.

Eat whole foods, especially vegetables and fruit which are extremely rich in key vitamins, minerals, antioxidant and anti-inflammatory phytochemicals.

A whole food diet of vegetables, fruits and healthy proteins will contain both macronutrients (types of food required in large amounts in the diet, consisting in carbohydrates, proteins and fats) and micronutrients (vitamins, minerals, certain essential amino-acids and certain essential fatty acids which we obtain from our food) which your body needs for optimal mental health:

  • It has been shown that micronutrients are capable of influencing genetic expression, with the result that depending on which micro and macro nutrients you absorb, genes for health or disease can be switched on or offVerheesen, R. and Schweitzer, C. (2009). Micronutrients and amino acids, main regulators of physiological processes. [online] Medical Hypotheses, 73 (4), pp. 498-502. Available at: [accessed 18 Aug. 2017].
  • These micronutrients are essential for optimal function of our organs, and a correct balance is crucial for our mental healthBurdon, R. and Kiroski, I. (2013). Current progress and impact of broad-spectrum micronutrients and the future of mental health research: insight from Dr. Bonnie Kaplan. [online] Journal of Undergraduate Research in Alberta, 3 pp. 1–3. Available at: [accessed 18 Aug 2017].
  • Micronutrients are essential for anti-oxidation, anti-inflammation and detoxification
  • Micronutrients are also essential for hormone balance, which is important for our mental health

Diets high in vegetables, fruit and wild fish are associated with a lower risk of depressive symptoms.Minocha, A. (2014). Is It Leaky Gut Or Leaky Gut Syndrome? Shreveport, LA: Logos Enterprises LLC., Perlmutter, D. and Colman, C. (2004). The Better Brain Book. New York: Riverhead Books, p. 62.

“Traditional diets” which are rich in whole foods, fruit, vegetables and fish, for instance Japanese and Mediterranean diets, have been found to lower the risk of depression and anxiety by 25-30% Jacka, F., Pasco, J., Mykletun, A., Williams, L., Hodge, A., O’Reilly, S., Nicholson, G., Kotowicz, M. and Berk, M.

Higher consumption of vegetables may cut the odds of developing depression by as much as 62%:Greger, M. and Stone, G. (2016). How Not To Die. London: Macmillan, p. 203.

  • Vegetables and fruits are rich in vitamins A, C and E, key antioxidants which act by reducing damage from free radicals, scavenging reactive oxygen species (ROS), and increasing antioxidant enzyme activity
  • Plant foods such as vegetables, fruits, herbs, teas, etc. are a great source of polyphenols which are anti-inflammatory and antioxidant, and as such have antidepressant qualitiesGreger, M. and Stone, G. (2016). How Not To Die. London: Macmillan, p. 57.
  • Monoamine oxidase (MAO) inhibitors are an established medication for the treatment of depression, and work by reducing excess MAO, which is believed to be in part responsible for depression
  • Many plant foods apples, berries, grapes, onions and green tea contain phytonutrients which naturally inhibit MAO
  • Vegetables and fruit are also rich in fibre which is helpful to gut health and improves digestion and absorption of nutrients

Let food be thy medicine and medicine be thy foodHippocrates, 4th century BC

To become more aware of your eating habits and how you could improve them for better mental health, try keeping a food and mood diary for two weeks, noting down what you eat, when you ate it, and how it made you feel, both physically and emotionally:Talbott, S. (2007). The Cortisol Connection. Alameda, CA: Hunter House, p. 228.

  • Notice any patterns which emerge
  • Notice emotional symptoms – do some foods make you feel happy, lethargic, spaced out, anxious, relaxed or even depressed?
  • Notice physical symptoms – do some foods give you bloating, gas, a fast beating heart, dizziness or indigestion?

Have a blood test with an integrative practitioner to check your nutritional levels (vitamins, minerals, EFAs, etc.) once a year if possible to identify any deficiencies.

Identify problem foods and beverages, by noticing any negative effects on your mental or physical health when you consume them, and/or with a food intolerance test. Once you have identified them, make sure to cut them out of your diet.

It should be possible to absorb all the nutrients we need for our mental health by eating whole foods. However, several factors can impact our ability to absorb these nutrients:

  • Poor diet:
    • A diet high in processed foods and beverages, low in whole foods
  • Poor lifestyle habits:
    • Stress, pollution, smoking, eating on the run, excess alcohol, medication, caffeine and sugar all increase the need for nutrients, and make it harder for our body to absorb nutrients
  • Poor nutrient content of whole foods:
    • Most fruit and vegetables are grown on poor soil which modern farming methods have depleted of minerals
  • Pregnancy and breastfeeding can leave us nutrient-depleted
  • Poor digestion and absorption due to:
    • Poor eating habits – eating too fast, skipping meals or eating while stressed can reduce nutrient absorption
    • Gut issues caused by stress, antibiotics, contraceptive pills, nutritional intolerances, NSAIDs, pollution
    • Problem foods and beverages that we may be allergic or intolerant to, and which can cause inflammation, digestion and absorption issues

As a result we may not be absorbing the right quantities of minerals, vitamins, EFAs and amino acids in order to build the right hormones and neurotransmitters for mental health. If you are deficient in certain micro-nutrients, you can take supplements.

More information on correcting your macro-nutrients:

For optimum mental health, it is necessary to identify nutritional deficiencies and imbalances in order to correct them. In an ideal world you would be able to work with a nutritionist, or other qualified health practitioner, to develop an optimal nutrition and supplement program:

  • This program would be customized to your specific mental health symptoms, nutritional deficiencies and your genetic make-up
  • Nutritional deficiencies can also be diagnosed through blood or urine analyses

However if you cannot work with a nutritionist or health practitioner, cultivate food awareness and become familiar with healthy eating guidelines and your nutritional needs.

Supplementation can be helpful in making sure that we are getting the right nutrients for our mental health. It is best to supplement according to our specific nutritional deficiencies, which can be identified with various diagnostic tests (blood, urine, etc.)

Choosing and using supplements

There are thousands of supplements on the market. Ideally, you would work with a trained dietician, nutritionist, doctor or healthcare practitioner to select the best products for your unique biochemical needs. Always read the label.

Check for the following:

  • A reputable manufacturer
  • Independent verification of active ingredients
  • Long history of safe use
  • Sources subject to clinical trials with published results
  • Check for contradictions with any existing medications
  • Free of: toxins, preservatives, fillers, binders, excipients, flow agents, shellacs, coloring agents, gluten, yeast, lactose, and other allergens
  • Always use supplements in addition to a healthy diet, never as a replacement or compensation for an unhealthy diet

Follow the recommended dose, unless you have been advised otherwise by a professional healthcare practitioner.

If you are on a budget

Supplements can become extremely expensive, particularly if you are tackling multiple symptoms. If this is an issue, the ideal supplement regime may be impossible to follow, however you may achieve significant benefits from following a regime based on the essentials:

  • A high quality multi-mineral/multi-vitamin containing all the basic essential vitamins and minerals
  • A complete B complex
  • Vitamin C
  • Omega 3 fatty acids – 1000mg fish oil containing EPA/DHA in a ratio of around 300/200
  • Magnesium and zinc at night
  • Probiotics — as broad spectrum as possible.

Supplementing with herbs and spices can be very helpful for addressing mental health symptoms, and in conjunction with correcting your nutrition and taking dietary supplements, can really boost your healing.

Herbs and spices can often be a second line of defence, when dietary supplements alone are not enough.

Ideally work with a herbalist to develop a herbal supplement programme.

How to heal with herbs and spices.

You can have an excellent diet, however as we have seen in gut issues, if your gut is leaky, or you have gut dysbiosis, or digestion issues, you will not absorb the correct macro and micro nutrients from your diet that you need to make the right hormones and neurotransmitters for optimal mental health.

Healing your gut can be one of the most important steps you can take in order to correct your nutrition and supplement. Read more about how to heal your gut by clicking on the links below.

Other lifestyle and psycho-spiritual solutions to correct nutritional imbalances

As we have seen in nutritional imbalances, lifestyle and psycho-spiritual factors such as stress and poor state of mind can also lead to nutritional imbalances. Below are some solutions to these contributors which, in turn, can help you correct your nutrition.

Correct breathing can help calm our nervous system, and is important for proper digestion and absorption of nutrients.

How to breathe better. 

Having a calm nervous system, especially around mealtimes, is essential to digesting and absorbing nutrients from our food. We can enhance our state of relaxation by practicing relaxation techniques regularly.

How to practise relaxation techniques.

A regular meditation practice can help to balance our nervous system, thereby improving our digestion and absorption of nutrients.

How to meditate.

Regular exercise helps to boost our metabolism, improve our blood and lymph circulation, and calm our nervous system. All these effect are helpful in improving our digestion and absorption of nutrients.

How to exercise right.

Mind body therapies such as yoga, qi gong, massage, acupuncture, etc. can help balance hormones, boost metabolism, calm the nervous system, improve blood and lymph circulation, all of which are helpful for digestion and absorption of nutrients.

How to practise mind body therapies.

Connecting with nature and natural light can calm the nervous system. A gentle walk in the country after a meal can help with digestion and absorption of nutrients.

Connect with nature and natural light. 

Getting enough sleep (7 to 8 hours a night) is important for digestion and absorption. A lack of sleep can cause inflammation and an increase in stress hormones, which over time can hamper our ability to digest and absorb nutrients. In order to optimise nutrients absorption, it is important to get enough sleep every night.

How to sleep better.

Using technology and social media around or during mealtimes can increase our stress levels and prevent us from being in the present moment. For optimal digestion and absorption, it is important not to multitask, to be relaxed, and focussed on the present moment. Therefore managing technology and social media use can help with optimal digestion and absorption of nutrients.

Manage your technology and social media use.

Mental therapy can help to calm the nervous system, by helping us get a perspective on our problems. It can help to feel more in control of our lives and heal past trauma. A more balanced nervous system is important for optimal digestions and absorption of nutrients.

Engage in mental therapy.
