If you’d like to keep your guests happy – serve barbecued chicken! How it works...

Your cookout will be even happier if you serve barbecued chicken...

Researchers at the University of Western Ontario explain: The chicken is rich in vitamin B6, which boosts our mood-boosting serotonin levels. Slather that in tomatoes and spices used in barbecue sauce and you’ll be getting even more blues-busters thanks to the high antioxidant levels in there.

If you’re looking for some happy side dishes – try some black-eyed peas, mustard greens or beets. They’ve all got feel-good folic acid. And don’t forget the blue tablecloth – it’s the color that evokes the most positive emotions from people.
