Food as a key disgust elicitor in infancy and childhood: Previous research and opportunities for future study

Disliked foods may have important value in the study of the development of disgust. The current review draws from literature across disciplines, including theories of disgust and studies of the development of eating behavior and food preferences, to highlight food as an important category of disgust responses across a wide age range, including children as young as 3 years old and adults. Children's disgust responses to certain types of food are considered to be both innate and culturally constrained behaviors, and their perceptions of other people's food choices indicate potential links between foods and cultural groups. We end by discussing several ongoing and future research areas, including connections between disgust responses and food rejection in infancy and children's food rejection behaviors across cultures.
