When you’re reaching for your next snack or meal, consider the contents and how they impact your emotional state. Here are several mood-boosting foods that will help you not only feel full, but good too. 1. Trail Mix: Nuts and seeds contain depression-combating protein and fibre, while berries contain energy-boosting sugars. 2. Fatty Fish: Contain omega-3s, an essential nutrient for maintaining long-term mental wellbeing. 3. Fermented Foods: Contain probiotics, which are great for the gut, and therefore the brain. 4. Dark Chocolate: Contains flavonoids, which have been linked to increased brain health (eat this in moderation, though).
