Studies have shown that diets high in fish oil, which contains omega-3 fatty acids, can fight anxiety and aggression — road rage, anyone?

The best way to up your daily dose of omega-3s is to regularly consume oily fish like salmon, herring and anchovies, but if seafood is not your thing consider a quality supplement. According to studies, fish oil also fights inflammation, boosts the immune system and might even ease the symptoms of bipolar disorder and clinical depression.
