City Know-hows
The built food environment has a significant influence on population health, for better and for worse. Evidence shows that urban planning can play a major role in creating food environments that support healthy food choices; however current transit-oriented developments have not yet considered access to healthy food outlets. We found evidence that a high proportion (79 – 84%) of food outlets could be classified as ‘unhealthy’ across eight transport hubs identified for accelerated development in New South Wales.

The problem
Research shows that density of unhealthy food outlets is associated with poorer diets and obesity, the latter are responsible for over 11 million deaths annually. Therefore, it is important to increase access to healthier food options, near where people ‘live, work and play’. This presents potential conundrums for urban planning and design, where intensification of existing urban places and development of new ones tend to be premised on the idea of vibrant places activated by out-of-home eating opportunities.
What we did and why
To evaluate the healthfulness of current food environments surrounding eight transport hubs identified for accelerated development, we identified the number and type of food outlets within a 1,200-metre radius of the rail or metro station for each transport hub. Food outlets were categorised as unhealthy, less healthy and healthy using an adapted version of the Food Environment Score which was developed by Australian nutrition and public health experts.
Our study’s contribution
We found evidence of a high proportion of food outlets classified as unhealthy across ALL transport hubs. The proportion ranged from 78.7% to 93.8% of total food outlets. The most prevalent food outlet type was restaurants/cafes (49.5%), followed by specialty foods (8.4%), and independent takeaways (7.6%) . Across all transport hubs, 64.1% of food outlets identified offered an online food delivery service(s).
Impacts for city policy and practice
This study provided us with the evidence that current food environments are predominantly unhealthy in transport hubs selected for further development. This warrants further attention from city planners. We suggest that further research is needed to understand ways that healthy food environments can be prioritised, especially in areas identified for re-zoning and intensified development. This will ultimately help combat the ubiquity of diet-related non-communicable diseases in increasingly urbanised cities.

Walking is one of the simplest ways to support health, but people only walk when streets feel comfortable, safe, and attractive. Our study shows that small design choices at the street level can strongly shape walkability, and that immersive virtual reality can help cities test these choices before making expensive changes.
