How does expressing gratitude prior to a family meal influence what one eats or how one acts?  Gratitude can take many forms, including grace, a blessing, or a prayer.  To this impact of gratitude, we surveyed 66 preschool families who either always or never prayed before their dinner. Saying a prayer before a meal was related to positive social behaviours such as helping prepare the meal (p < .01) and eating at the table (p < .05). It was also modestly related to healthier eating behaviours, such as serving a wider variety of items at dinner (5.8 vs. 4.9 items).  This research has gratitude-expressing implications for both religious and nonreligious families.
