A comprehensive study from the UK has revealed that “fussy eating” in children is primarily influenced by genetics rather than parenting styles. The research, published in the Journal of Child Psychology and Psychiatry, examined the eating habits of 2,400 identical and non-identical twins from ages 16 months to 13 years.
The findings indicate that identical twins exhibited significantly similar food preferences, suggesting a strong genetic component to food fussiness. The study found that genetic differences accounted for about 60% of variations in food selectivity at 16 months, rising to 74% between ages three and 13.
While genetic factors play a major role, the research also emphasizes that parents can still make a difference, especially in early childhood, by introducing a variety of foods. Professor Clare Llewellyn, the study’s senior author, noted that these insights aim to alleviate parental anxiety regarding children’s eating habits, emphasizing that fussy eating is a common, inherited trait rather than a reflection of parenting quality.
