Mental Health & Nutrition

When I present on the topic of mood and nutrition, I’m often met with surprise. Many people believe their moods are fixed - an unchangeable result of their personality or genetics. But the truth is, we have the power to influence our moods through the choices we make every day, including what we eat.
For so many of my clients, learning that they can make changes to improve their mental health is a game-changer. It’s empowering to realise that by nourishing our bodies with the right foods, we can also nourish our minds.

In recent years, research has increasingly highlighted the vital role that nutrition plays not just in our physical health but in our mental well-being too. It’s becoming clear that what we eat can profoundly influence how we think, feel, and even manage stress and anxiety.

Key nutrients that support mental health: 

  1. Omega-3 Fatty Acids

    • Why They Matter: Omega-3s are essential fats that our bodies cannot produce on their own. These fats are crucial for brain function, particularly in regulating mood and cognitive processes. Studies have shown that a diet rich in omega-3s can help reduce symptoms of depression and anxiety.
    • Where to Find Them: You can get your dose of omega-3s from fatty fish like salmon, mackerel, and sardines, as well as plant-based sources like flaxseeds, chia seeds, and walnuts.
  2. B Vitamins

    • Why They Matter: B vitamins, especially B6, B12, and folate, are integral in the production of neurotransmitters like serotonin and dopamine, which regulate mood and energy levels. Deficiencies in these vitamins have been linked to an increased risk of mood disorders, including depression.
    • Where to Find Them: Incorporate animal proteins, whole grains, eggs, leafy greens, and legumes into your diet to ensure you're getting enough B vitamins.
  3. Antioxidants

    • Why They Matter: Antioxidants help combat oxidative stress in the brain, which can lead to inflammation and has been associated with mental health issues. By protecting brain cells, antioxidants can support cognitive function and emotional balance.
    • Where to Find Them: Colorful fruits and vegetables like berries, citrus fruits, dark chocolate, and leafy greens are all rich in antioxidants.
  4. Vitamin D
    • Why They Matter: Vitamin D plays a crucial role in mood regulation by supporting serotonin production, reducing inflammation, and protecting brain health. Adequate levels of Vitamin D help maintain stable circadian rhythms, which are vital for mood stability. It's particularly important in preventing and alleviating Seasonal Affective Disorder (SAD), a type of depression that occurs in winter when sunlight exposure is low. Ensuring sufficient Vitamin D levels can have a positive impact on overall mental health and well-being.

      Where to Find Them: Vitamin D can be naturally obtained from several sources, with sunlight being the most prominent, as your skin produces Vitamin D when exposed to it. Dietary sources include fatty fish like salmon, sardines, and tuna, which are rich in Vitamin D. Egg yolks also contain small amounts of this essential nutrient.

The Gut-Brain Connection: How Your Gut Health Affects Your Mind

The relationship between your gut and brain is so significant that it’s often referred to as the "gut-brain axis." The gut houses trillions of bacteria that produce neurotransmitters like serotonin, which directly impact mood and behaviour. A healthy gut can help maintain a balanced mood, while an imbalanced gut can contribute to feelings of anxiety and depression.

  • Probiotics and Prebiotics:

    • Probiotics are live beneficial bacteria found in fermented foods like yoghurt, kefir, sauerkraut, and kimchi. These can help replenish good bacteria in the gut, promoting a healthy balance.
    • Prebiotics are types of fibre that feed the good bacteria in your gut. Foods rich in prebiotics include garlic, onions, leeks, asparagus (I am eagerly waiting for my plants to pop out of the ground any day now!), and bananas.
  • Fibre: Fibre is essential for gut health as it helps maintain regular bowel movements and feeds the beneficial bacteria. A diet rich in fibre from fruits, vegetables, whole grains, and legumes can support a healthy gut microbiome.

Eating for a Healthy Mind: Practical Tips

  • Balance Your Plate: Aim to include a variety of nutrients in every meal. Combine protein, healthy fats, and complex carbohydrates to keep your blood sugar stable, which can help manage mood swings.

  • Stay Hydrated: Dehydration can affect your concentration and mood, so make sure you're drinking enough water throughout the day.

  • Limit Processed Foods: Highly processed foods, especially those high in sugar and unhealthy fats, can contribute to inflammation and negatively impact your mental health.

  • Mindful Eating: Pay attention to how certain foods make you feel. Keeping a food diary can help you identify any dietary patterns that might be affecting your mood.

The Bottom Line:

Your diet is a powerful tool that can influence your mental health in significant ways. By focusing on nutrient-dense foods that support brain function and gut health, you can boost your mood, enhance cognitive function, and improve overall well-being. Remember, nourishing your body is just as important as nourishing your mind - small dietary changes can lead to big improvements in how you feel!

I also believe that taking care of your sex hormones, thyroid health, liver health, and managing inflammation can significantly impact how we feel. Perhaps that could be the focus of my next write-ups!
