You Snacked on Microwave Popcorn
No matter what's irking you—your partner's tap-tap-tapping foot, a snarky comment, a printer jam—the wrong type of popcorn may play a role in turning annoyance into full-blown rage. Other culprits can include frozen pizza, crackers, canned frosting, coffee creamer...or anything else that contains high levels of trans-fatty acids (partially hydrogenated oils—see this list). There's a strong association between anger issues and the consumption of trans fats, claim researchers at the University of California at San Diego, who surveyed people's eating habits and moods. The theory is that trans fats may inhibit absorption of healthy omega-3 fats, which are known for tamping down hostile behaviors and making us feel calmer.
