A new study led by researchers from UCL, King’s College London, and the University of Leeds has revealed that fussy eating is primarily influenced by genetic factors, remaining a stable trait from toddlerhood through early adolescence. Published in the Journal of Child Psychology & Psychiatry, the research highlights the extent to which genetics play a role in children’s eating behaviors.
The study analyzed survey results from parents of identical and non-identical twins in England and Wales, tracking their eating habits from 16 months to 13 years of age. Findings indicated that food fussiness—characterized by a limited range of accepted foods due to selectivity about tastes and textures—peaked around age seven and gradually declined thereafter.
Key findings include:
Genetic differences accounted for 60% of the variation in food fussiness at 16 months, increasing to over 74% by ages three to 13.
Environmental influences, such as family meal settings, were significant during toddlerhood but diminished as children grew older. Unique environmental factors became more important in later years, influenced by individual experiences and social interactions.
Lead author Dr. Zeynep Nas emphasized that understanding fussy eating as an innate behavior may help reduce parental guilt, clarifying that it is not solely a reflection of parenting style. “Fussy eating is not necessarily just a ‘phase’ but may follow a persistent trajectory,” she noted.
Senior author Professor Clare Llewellyn highlighted the importance of early intervention, suggesting that consistent exposure to a variety of foods during toddlerhood can encourage a broader diet. “Shared environmental factors play a role in early years, indicating that family dynamics can influence eating habits at that stage,” she added.
The research utilized data from the Gemini study, the largest twin cohort investigating genetic and environmental contributions to early growth, involving 2,400 sets of twins. Parents completed questionnaires regarding their children’s eating behaviors at various ages, allowing the researchers to analyze genetic versus environmental influences.
The results showed that while fussy eating is largely hereditary, it is not immutable. Parents can still encourage diverse eating habits throughout childhood, although peer influence may become more significant as children reach their teenage years.
Limitations of the study included a smaller participant pool at age seven and a demographic skew towards white British households from higher socio-economic backgrounds. The researchers advocate for future studies to explore diverse populations to understand the broader cultural impacts on food preferences.
Overall, this research sheds light on the complex interplay of genetics and environment in shaping children’s eating habits, providing insights for parents and healthcare providers in addressing fussy eating behaviors.
