University students who recall warm, secure memories from childhood are more likely to maintain healthier diets, according to a research published in the journal Interpersonal and Biological Processes. The study, involving nearly 3,000 Chinese university students, sheds light on how early emotional experiences continue to shape physical health well into young adulthood.
Researchers from Jishou University surveyed 2,984 students aged 17–26, examining the links between early warm and secure memories, anxiety levels, physical activity, and eating habits. The findings revealed that students with stronger positive childhood memories were significantly more likely to report healthier dietary patterns, including greater consumption of fruits and vegetables and lower intake of sugary drinks.
Anxiety emerged as a key factor connecting early memories to food choices. Students who reported fewer warm childhood experiences tended to have higher anxiety levels, which in turn was associated with poorer eating habits. The researchers suggest that anxiety may push individuals towards high-calorie, high-sugar foods as a way of seeking temporary emotional relief.
The study found that anxiety partially explained the relationship between childhood memories and diet, accounting for around 21% of the overall effect. This means that even when anxiety was taken into account, early warm memories still directly predicted healthier eating, suggesting the relationship operates through multiple pathways.
Physical activity was found to play a moderating role in the connection between early memories and anxiety. Students who were more physically active showed a weaker link between lacking warm childhood memories and experiencing anxiety. Regular exercise appeared to buffer some of the psychological impact of difficult early experiences, reducing the extent to which those memories translated into higher anxiety.
The research highlights how factors from very early in life can have measurable effects on health behaviours at university, a period when many students are forming long-term dietary habits without parental oversight. Financial pressures, academic stress, and easy access to fast food all make healthy eating more difficult during the university years, meaning that psychological resilience developed in childhood may play a more important role than previously recognised.
More than a quarter of university students have been found to exhibit disordered eating behaviours in previous research, and unhealthy diets during adolescence have been associated with impaired memory function and low mood. This study adds to a growing body of evidence suggesting that addressing mental well-being is inseparable from promoting good nutrition in young people.
The authors acknowledge that the cross-sectional design of the study means causal relationships cannot be confirmed. All data were self-reported, which introduces the possibility of recall bias. They call for future longitudinal research spanning multiple countries and age groups to build on these findings.
The researchers recommend that health interventions targeting university students should draw on the psychological resource of positive early memories while also encouraging regular physical activity to help manage anxiety.
