Title Amount of Time to Eat Lunch Is Associated with Children's Selection and Consumption of School Meal Entree, Fruits, Vegetables, and Milk Type Journal Article
Year 2016 Publication Journal of the Academy of Nutrition and Dietetics Abbreviated Journal J Acad Nutr Diet
Volume 116 Issue 1 Pages 123-128
Keywords Animals; Child; Diet; *Eating; Ethnic Groups; Female; *Food Preferences; *Food Services; Fruit; Humans; *Lunch; Male; Milk; Prospective Studies; *Schools; Students; Time Factors; Vegetables; Fruit intake; Lunch period length; Milk intake; School lunch; Vegetable intake
Abstract BACKGROUND: There are currently no national standards for school lunch period length and little is known about the association between the amount of time students have to eat and school food selection and consumption. OBJECTIVE: Our aim was to examine plate-waste measurements from students in the control arm of the Modifying Eating and Lifestyles at School study (2011 to 2012 school year) to determine the association between amount of time to eat and school meal selection and consumption. DESIGN: We used a prospective study design using up to six repeated measures among students during the school year. PARTICIPANTS/SETTING: One thousand and one students in grades 3 to 8 attending six participating elementary and middle schools in an urban, low-income school district where lunch period lengths varied from 20 to 30 minutes were included. MAIN OUTCOME MEASURES: School food selection and consumption were collected using plate-waste methodology. STATISTICAL ANALYSES PERFORMED: Logistic regression and mixed-model analysis of variance was used to examine food selection and consumption. RESULTS: Compared with meal-component selection when students had at least 25 minutes to eat, students were significantly less likely to select a fruit (44% vs 57%; P<0.0001) when they had <20 minutes to eat. There were no significant differences in entree, milk, or vegetable selections. Among those who selected a meal component, students with <20 minutes to eat consumed 13% less of their entree (P<0.0001), 10% less of their milk (P<0.0001), and 12% less of their vegetable (P<0.0001) compared with students who had at least 25 minutes to eat. CONCLUSIONS: During the school year, a substantial number of students had insufficient time to eat, which was associated with significantly decreased entree, milk, and vegetable consumption compared with students who had more time to eat. School policies that encourage lunches with at least 25 minutes of seated time might reduce food waste and improve dietary intake.

Title Social facilitation of eating: effects of social instruction on food intake Type Journal Article
Year 1992 Publication Physiology & Behavior Abbreviated Journal Physiol Behav
Volume 52 Issue 4 Pages 749-754
Keywords Adolescent; Adult; Arousal; Computer Simulation; Dietary Fats/administration & dosage; *Eating; Energy Intake; Feeding Behavior/*psychology; Female; Humans; Male; Middle Aged; Motivation; Nutritive Value; *Reinforcement, Social; *Social Facilitation; Social Isolation; Sodium, Dietary/administration & dosage
Abstract To investigate whether social influences cause increases in eating behavior, thirty undergraduate psychology students completed a diet diary for three 5-day periods. Subjects were instructed to either eat alone or eat with other people, actively eating with them for two of these periods. For the third period, subjects were instructed to eat as they normally would (with or without other people present). When instructed to eat with others present, subjects overall consumed more food, water, sodium, and alcohol than when they were instructed to eat alone. In the normal condition, food intake was 60% higher when the subjects ate with others present than when they ate alone. These results suggest that social facilitation has a causal influence on eating which increases food intake.
