The old saying, "You are what you eat" is apparently true in more ways than we realize.  People have multiple reasons for choosing what they eat, including comfort and self-validation. Pre-meal "rituals" make our food taste better.  Having “Happy Birthday” sung to you in a restaurant heightens the anticipation of digging into birthday cake. Clinking glasses before drinking a toast, and rubbing chopsticks together make dining a more emotionally gratifying experience.

The widespread popularity of social media has taken this to a new level. When you're scanning Facebook, or Instagram, you may not care to see photos of other people's meals. The food pornographers among us derive an emotional gratification from snapping a pic with their smartphones  and posting them online. Experts say these rituals pique our attention and heighten our involvement with the experience of eating, which makes us enjoy it more.
