Picky Eating in Normally Developing Children and Young Adults

Abstract

This chapter deals with picky eating (PE) in normally developing children and adults. PE is a central component of avoidant/restrictive food intake disorder (ARFID) but not an eating disorder in itself. A large proportion of children go through a phase of PE, which usually resolves itself. A minority of children continue to be highly selective and neophobic. Extreme and consistent restricted eating in children can arrest development and cause severe health problems. There is (arguable) evidence that consistent picky eating from early childhood into preadolescence is a risk factor for restrictive eating disorders such as ARFID and anorexia nervosa. There is a growing body of research on PE in young adults; there is some evidence that adult PE is related to a less healthy lifestyle and is associated with emotional and social dysfunction and distress. This chapter reviews the definition, extent, duration, precursors, and repercussions of PE in children and young adults. It uses vignettes of picky eaters to illustrate some of the points raised in the review. In conclusion, it summarizes some of the lessstudied issues that require further research and offers practical advice.
