Certain foods can improve our mood by boosting serotonin production in the brain, releasing energy and making us feel alert and motivated. A diet high in these foods can make a huge difference to how we feel physically, mentally and emotionally.

• Flaxseeds, sunflower seeds, pumpkin seeds, sesame seeds, peanuts, almonds, cashews and, in particular, walnuts, boost serotonin production.
• Essential fatty acids increase serotonin production. Omega-3 fatty acids found in oily fish, evening primrose and flax oil, are helpful.
• Eggs contain crucial amino acids and the essential fatty acids needed to make serotonin.
• Baked sweet potatoes, mushrooms, corn, broccoli, spinach and soy products all help stabilise serotonin levels.
• Poultry – turkey and duck in particular – contain tryptophan, which boosts serotonin production in the brain.
• Try the Grace Happy Days Smoothie (pictured) – cacao and banana both boost serotonin levels. Blend together 2tsp raw cacao powder, 1 banana, 100ml almond milk, ½tsp maca powder, 1tbsp chia seeds, pinch of ground cinnamon and 1tbsp coconut yogurt.
