Modeling Nutrient Intake: The Role of Dietary Information

摘要

Measuring the effect of nutrition information on an individual's intake ofdietary fiber is crucial for understanding and quantifying the linkage between nutrition education programs and actual consumption behavior. Dietary information and intake data for a sample of U.S. household meal planners are used to estimate the effect of fiber-specific information on dietary fiber intake. The information variables are measured using survey responses to a series of questions on fiber content of foods, attitude toward consuming fiber-rich foods, and awareness of fiber-health links. Results indicate that attitudes about eating high-fiber foods and awareness of the linkage between dietary fiber intake and some diseases are important determinants of an individual's fiber intake.
