19. Brazil Nuts: The Selenium Superstar

Brazil nuts may seem like an ordinary snack, but they hold a superpower in stress management—they are one of the richest natural sources of selenium, a trace mineral that plays a crucial role in mental well-being. Studies have linked low selenium levels to increased anxiety, irritability, and depression, making it an essential nutrient for mood regulation and emotional stability. Selenium also supports thyroid function, which directly influences energy levels, metabolism, and the body’s ability to manage stress. A well-functioning thyroid ensures that hormone levels remain balanced, preventing mood swings and fatigue. Additionally, selenium is a powerful antioxidant that helps reduce inflammation and oxidative stress, both of which are associated with higher levels of anxiety. The best part? You only need one or two Brazil nuts per day to meet your daily selenium requirements.
