Nutrition and Mental Health
Fuelling Your Brain for Optimal Function
When we think about looking after our mental health, we often focus on therapies, stress management techniques, and mindfulness. But what if I told you the food you eat plays a crucial role in your mental wellbeing? It's true! The connection between nutrition and mental health is becoming increasingly clear, with research demonstrating that what we consume can significantly impact our mood, cognitive function, and overall psychological health. Then there’s the gut-brain connection.
What is the gut-brain connection?
The gut and the brain are in constant communication, linked by a complex network known as the gut-brain axis. The gut microbiome, the trillions of bacteria residing in our digestive system, plays a crucial role in this connection. These bacteria produce neurotransmitters, such as serotonin and dopamine, which influence our mood, sleep, and cognitive function. An unhealthy gut microbiome, on the other hand, can contribute to inflammation and imbalances in neurotransmitter production, potentially increasing the risk of mental health problems. Now, I hear you ask…
Are there key nutrients for mental wellbeing?
Yes! There are, these are some:
Omega-3 Fatty Acids: Found in oily fish (salmon, mackerel, sardines), flaxseeds, and walnuts, omega-3s are essential for brain health. They support cognitive function, mood regulation, and may help protect against depression and anxiety.
B Vitamins: B vitamins, particularly B6, B9 (folate), and B12, are vital for neurotransmitter production and brain function. Leafy green vegetables, legumes, and fortified cereals are excellent sources. Other sources include dairy such as cow’s milk and butter, or certain types of meats.
Vitamin D: Often referred to as the "sunshine vitamin," vitamin D plays a role in mood regulation and cognitive function. While sunlight is the best source, it can also be found in oily fish, eggs, and fortified foods. It’s not unusual to have insufficient levels of Vitamin D in our country, however. Very little sunshine throughout the year contributes to this.
Magnesium: This mineral is involved in over 300 bodily processes, including nerve function and stress response. Leafy greens, nuts, seeds, and whole grains are good sources.
Zinc: Zinc is essential for brain development and function, playing a role in learning and memory. It can be found in meat, shellfish, legumes, and nuts.
The important thing to remember is that all of these are easy enough to get into your diet, whether you have a diet that excludes animal products or not. It might just require a little more careful planning. On that basis, you may be somebody who just needs a plan, and you don’t like to think about planning food too much. So here are some ideas.
What are some diets for good mental health?
Mediterranean Diet: This diet, rich in fruits, vegetables, whole grains, legumes, and olive oil, has been linked to a reduced risk of depression and cognitive decline.
Limiting Processed Foods: Highly processed foods, laden with sugar, unhealthy fats, and artificial additives, can negatively impact mood and cognitive function.
Prioritise whole foods: Base your diet on fruits, vegetables, whole grains, lean protein, and healthy fats.
Cook at home more often: This allows you to control the ingredients and make healthier choices.
Stay hydrated: Dehydration can affect mood, concentration, and energy levels.
Limit caffeine and alcohol: While these substances can provide a temporary boost, they can also disrupt sleep and exacerbate anxiety.
And in summary?
By nourishing your body with the right nutrients, you can support your brain and enhance your mental wellbeing. Remember, food is not just fuel; it's medicine. Making conscious food choices can be a powerful tool in your journey towards optimal mental health.
Can you help me?
Kind of. I’m not a dietician, so you can’t expect loads of advice from me on nutrition, but I can always consult with you on the types of things you might want to prioritise, and even go over strategies for making the time for eating well, strategies for planning your meals, crafting a selection that caters for sensory differences, among other things. Let’s have a chat about lifestyle and diet.

Final thoughts
The modern world demands our constant attention. We are often pulled from pillar to post. For this reason, we find ourselves eating junk food, forgetting to drink, and deprioritising that which is easy to deprioritise. I hope this blog helped you think about how important it is to eat well, and to start thinking about it. Even if that’s just your first step.
