A healthy diet is a key ingredient to good health and can help prevent a number of adverse health conditions. Although many people can describe a healthy diet, they often cannot accurately report the nutritional content of their own diets. In this study, daily dietary feedback consisting of recommended daily nutrient values accompanied by estimated calorie and fat data of daily food purchases was provided to four college undergraduates. The estimated calorie and percentage of calories from fat data were based on records of participant purchases at university dining establishments. The introduction of daily dietary feedback resulted in the students purchasing fewer calories and fewer calories from fat per day.
