A new study led by researchers from UCL, King’s College London, and the University of Leeds found that fussy eating is mainly influenced by genes and is a stable trait from toddlerhood to early adolescence. The study, published in the Journal of Child Psychology & Psychiatry, analyzed data from twins in England and Wales from 16 months to 13 years old. Genetic differences accounted for 60-74% of food fussiness variation, while environmental factors showed only minimal effects. The study suggests that fussy eating is largely innate, not necessarily a result of parenting, and interventions in early childhood can help children eat a wider range of foods.
