Slow Food Movement. An international movement begun by Carlo Petrini with a forerunner organisation, Arcigola, founded in 1986 to resist the opening of a McDonald's (fast food restaurant) near the Spanish Steps in Rome.
One such influence is mindful eating, or focusing on the food you're eating. Enjoy the aroma, savor every bite, eat slowly, and chew each mouthful thoroughly for maximum pleasure. Slow eating releases more flavors from food and extends the time the food lingers in your mouth.
