Subjects rated food items based on A) Preference (i.e. “wanting/desirability”), rated on a scale of 1–4 B) Perceived healthiness, rated on a scale of −3 to +3 and C) Tastiness, rated on scales −3 to +3. Food items rated 3 or 4 in the preference/desirability block were scored as “preferred”, while those rated 2 or 3 in the healthiness/tastiness blocks were rated as perceived “healthy”/“tasty” and −2 or −3 as perceived “unhealthy”/“untasty”.
