In a study, subjects who were told that a given food was very flavorful were more willing to try the food and more likely to enjoy it than were subjects who were told that the food was nutritious. Few people, when given a choice between foods that are flavorful but not nutritious and foods that are nutritious but not flavorful, will choose the foods that are nutritious but not flavorful. Most people currently believe that wholesome foods are more flavorful, on average, than unwholesome foods are. The studies that revealed that people choose the foods they eat primarily on the basis of flavor also revealed that people rated as most flavorful those foods that were least nutritious.
