If You're Feeling Anxious
You can't always jet off to a tropical paradise when you need to relax, but you can channel some laid-back vibes by snacking on Brazil nuts. These nuts are loaded with selenium (just one ounce contains over 700 percent of your recommended daily intake), a trace mineral that appears to play an important role in the brain. Several studies have shown that low levels of selenium lead to increased anxiety and depression, while greater selenium intake has been linked to lower anxiety and an overall improvement in mood. Brazil nuts aren't the only selenium-rich food, though; you can also try tuna, garlic, or mushrooms when you feel your anxiety rising.
