Objective: To test the effects of a cooking program on healthy food decisions. Design: An experimental between-subjects design with 3 conditions: healthy, unhealthy, and control. Setting: Class settings in 5 different schools. Participants: One hundred twenty-five children between 10 and 12 years of age. Interventions: Video clips of cooking program containing healthy foods versus cooking program containing unhealthy foods versus control program. Main outcome measures: Healthy versus unhealthy food choice. Analysis: Logistic regression analysis, with the control condition as a reference in the first contrast test and the unhealthy food condition as a reference in the second contrast, to examine effects on food choice between conditions. Results: Children who watched the cooking program with healthy foods had a higher probability of selecting healthy food than children who watched the cooking program with unhealthy foods (P = .027), or with the control condition (P = .039). Conclusions and Implications: These findings indicated a priming effect of the foods the children were exposed to, showing that nutrition education guided by reactivity theory can be promising. Cooking pro- grams may affect the food choices of children and could be an effective method in combination with other methods to improve their dietary intake.
