This paper presents the evaluation of positive promotion of squash (<span name="style_italic">Sechium edule</span>) and broccoli (<span name="style_italic">Brassica oleracea</span> L) on attitude (positive, negative or neutral) and sensory liking of 213 preschool children between 4 and 6 years old. For that propose, in San José, Costa Rica, during the year 2012, the strategy for encouraging reading known as <span name="style_italic">Kamishibai</span> was used, exposing children to 10 interventions in the form of storytelling sessions, where they were divided into four groups according to their gender and the gender of the character in the story that promoted the vegetables. Determinations for attitude, by an interview, and liking, by sensory panel, were established before and after the intervention with the <span name="style_italic">Kamishibai</span>. All activities were conducted in a playground set for this purpose in the classroom. From the results, it can be argued that the use of the <span name="style_italic">Kamishibai</span> as a strategy for encouraging reading increased significantly both the positive attitude and the liking for the vegetables in children (p&lt;0.05), regardless of their gender and the gender of the characters who made the promotion. as a strategy for encouraging reading increased significantly both the positive attitude and the liking for the vegetables in children (p<0.05), regardless of their gender and the gender of the characters who made the promotion.
