Feeding a child can often feel like navigating a minefield, especially when faced with a picky eater. This common dilemma affects countless families, leading to mealtime struggles, frustration, and concern over nutritional needs. A new study aims to shed light on this age old dilemma, suggesting that picky eating may genetic.

A recent study from researchers at University College London and King’s College London reveals that picky eating may be significantly influenced by genetics rather than parenting practices.

“We would like to emphasize that the behavior is not due to poor parenting,” Zeynep Nas, PhD, a UCL researcher and one of the lead authors of the study said in an interview with Parents.com. “And differences we see between children in their fussy eating may be largely due to genetic differences between them.”

The study analyzed data from 4,804 British twins and found that identical twins, sharing 100% of their genes, showed more similarity in picky eating behaviors than non-identical twins, who share only 50%. These findings indicate a strong genetic component to why some children are more selective with their food. Dr. Bad emphasizes that this research aims to alleviate the guilt parents often feel regarding their children’s eating habits.

“We hope that this will alleviate some of the guilt and blame experienced by many parents and that it is reassuring for many people to know that genetics play a large role in explaining why some children are fussier than others about the foods they are willing to eat,” Dr. Nas said.

While genetics play a crucial role, the environment also influences feeding behaviors, particularly during toddlerhood. Shared experiences, such as family meals, are impactful during early development, but non-shared environments, like peer interactions, can shape eating habits later on. Dr. Nas points out that although genetics influence picky eating, tailored environmental interventions can still support individual needs.

“The fact that the tendency to be a fussy eater is under genetic influence does not mean that the environment doesn’t matter,” says Dr. Nas. “In fact, the study indicates that toddlerhood could be a key window of opportunity to support children with their fussy eating.”

Experts caution against mistaking picky eating with more serious feeding disorders, which affect a significant number of young children. Pediatric feeding disorder (PFD) can emerge when eating struggles persist and affect a child’s nutritional intake or mental health. Early intervention is key to mitigating potential long-term issues.
