Impact of Increasing the Availability of Healthier vs. Less-Healthy Food on Food Selection: A Randomized Laboratory Experiment (2021)

This experiment explores how changing the availability of healthier versus less-healthy food options affects snack selection in a controlled setting. Participants presented with more healthy options were more likely to choose healthier snacks. However, differences were not statistically significant based on socio-economic position, suggesting that increasing healthy food availability could promote better choices across various demographics, though further research is needed to confirm.
