The connection between diet and mood is a topic of growing interest in the world of nutrition and mental health. While there’s no magic food to cure all your emotional woes, it’s becoming increasingly clear that what you eat plays a significant role in how you feel. In this blog post, we’ll explore some of the dietary patterns that can improve your mental well-being.

Over the years of research, the chemistry of food has been shown to directly impact mood. A study titled ‘Food and Mood: How do diet and nutrition affect mental well-being (2020)’ suggests that through multiple hormonal, inflammatory and neural pathways, a good quality diet can have a profound impact on your mental health improving mood, stress and cognitive function.

Here are the top four dietary patterns that you can focus on in your diet to stabilise your mental well-being.

Complex Carbohydrates:

As carbohydrates are the brain’s main energy source, ensure you include wholegrains, legumes and starchy vegetables as part of your diet. This will provide a steady supply of energy to your brain and can help stabilise your mood by regulating blood sugar levels.

Nothing wrong with the occasional chocolate bar as part of a well-balanced diet however minimise your intake of such simple carbohydrates as these foods can put your mental well-being on a roller-coaster ride.

Omega-3 Fatty Acids

Approximately 8% of your brain’s weight is comprised of omega 3 fatty acids, which we need to get from foods as our body can’t create omega 3. Foods like fatty fish (salmon, mackerel, sardines), flaxseeds, and walnuts contain omega-3 fatty acids, which keep dopamine levels high in the body, reducing symptoms of depression and anxiety.

Prebiotics and Probiotics

Your gut and brain are in constant communication through what’s known as the gut-brain axis. A healthy gut microbiome, composed of trillions of microorganisms, can influence your mood and mental health. To support a healthy gut, consume foods rich in prebiotics and probiotics. Probiotics include foods that have live micro-organisms in them including natural yogurt, kefir, sauerkraut and kimchi. Prebiotic foods are high-fibre foods like oats, asparagus, chickpeas, garlic and bananas.

Balancing meals and snacks with lean protein sources provide the body with the building blocks to produce neurotransmitters like serotonin. Serotonin is often referred to as the “feel-good” neurotransmitter because of its association with feelings of well-being and happiness. Serotonin helps regulate mood, alleviate depressive symptoms and prevents extreme mood swings. Include poultry, legumes, fish or dairy products across the day to get the benefits of serotonin.

While diet alone cannot replace professional mental health care, it can play a significant role in supporting mental well-being. By focusing on nutrient-rich foods, you can harness the power of nutrition to boost your mood and overall mental health.
