A new direction for public health care: changing cafeteria eating habits.

A "Food for Thought" game, an eight-week, media-based nutrition program designed to influence food choices in a cafeteria setting, was conducted in a National Institutes of Health employee cafeteria. Its purpose was to encourage customers to select lower-caloric food during lunch. The effects of the program on food choices and total calories of food purchased each day were measured by time series analyses. During the eight-week intervention period, skim milk purchases increased, and dessert and bread sales, as well as average number of calories purchased per day per person, declined significantly. Some evidence for a maintenance effect over a ten-week follow-up period was obtained. The "Food for Thought" game delivered nutrition education in an upbeat but unobtrusive way. Although people patronize cafeterias to eat, socialize, and relax and not to be educated, this program had only minimal requirements for participation. The result was a high level of interest and involvement. People can "learn while they eat," if careful attention is paid to customer needs and principles of effective communication.
