A large study in the UK has concluded that fussy eating is largely down to genetics, not parenting styles, providing a much-needed relief for parents who struggle with picky eaters. The research, published in the *Journal of Child Psychology and Psychiatry*, tracked the eating habits of identical and non-identical twins from 16 months to 13 years old.
The findings revealed a strong genetic component to fussy eating, with identical twins showing much more similar eating patterns than non-identical twins. While environmental factors play a role, particularly in early childhood, genetic influences become more prominent with age, accounting for nearly 75% of the variation in food fussiness by adolescence.
“The reason why some children are quite ‘finicky’ with trying certain sorts of food and others are more adventurous is largely down to genetic differences between children rather than parenting styles,” explained Professor Clare Llewellyn, senior author of the study.
Dr Zeynep Nas, lead author, emphasized that these findings should help ease parental anxiety about picky eating, a common and often stressful experience. However, she also stressed that strategies like offering a variety of foods and creating a calm dining environment can still be helpful, particularly for younger children.
While fussy eating is common, it is important to differentiate it from Avoidant Restrictive Food Intake Disorder (ARFID), a relatively new eating disorder characterized by extreme food selectivity. ARFID requires specialist support and is not simply a case of picky eating.
The research, conducted by scientists from UCL, King’s College London, and the University of Leeds, involved a predominantly white British sample from wealthier backgrounds. Future research will need to explore food fussiness in non-western populations where cultural and environmental factors may differ.
