URGENT UPDATE: A groundbreaking study by Monash University and Deakin University in partnership with Ritchies IGA supermarkets has significantly changed grocery shopping habits across Australia. The initiative, known as “nutritional serve pricing,” has led to an impressive increase in daily vegetable purchases, with shoppers buying an average of 60 grams more vegetables each day.
Launched in March 2024, this innovative pricing model displays the cost of a standard serve alongside traditional per-kilogram pricing, making healthy choices more accessible and affordable for families. Results from the national evaluation show that overall, vegetable purchase volumes soared by 7.5 kilograms daily across participating stores. This comes as alarming statistics reveal that less than 6.5 percent of Australian adults meet the recommended vegetable intake.
The “nutritional serve pricing” strategy presents prices based on a 75-gram serve, aligning with the Australian Dietary Guidelines. For instance, carrots priced at $2.99 per kilogram are now framed as costing about 22 cents per 75-gram serve. This new approach not only highlights affordability but also simplifies budgeting for shoppers.
Researchers analyzed 850 consecutive days of de-identified loyalty card data, making this the largest real-world assessment of pricing communication for vegetables in Australia. The study focused on 56 stores that operated throughout the observation period, ensuring a comprehensive evaluation without disruptions like store openings or renovations.
According to Associate Professor Fiona Newton from Monash Business School, while these findings indicate purchasing patterns rather than confirmed consumption, they showcase a significant behavioral shift towards healthier choices following the introduction of per-serve pricing. “Vegetable consumption in Australia remains far below recommended levels, and many families feel that healthier choices are less affordable,” she stated.
Deakin University’s Professor Josh Newton emphasized the unique opportunity this partnership created, allowing researchers to study shopping behavior in a natural retail environment without promotional distractions.
Fred Harrison, chief executive of Ritchies IGA, highlighted the supermarket’s potential to facilitate healthier choices for families by making vegetables more appealing and understandable. The initiative has garnered support from AUSVEG, with chief executive Michael Coote calling it a practical, research-backed tool to enhance vegetable consumption as part of the Plus One Serve program.
As this initiative unfolds, it is clear that the collaboration between academia and retail is making strides in public health. The implications for families and communities striving for healthier eating habits are profound.
What happens next? As momentum builds, expect to see broader discussions on how pricing strategies can combat poor dietary habits and how other supermarkets might adopt similar approaches to support health initiatives.
Stay tuned for more updates on this developing story, as the impact of nutritional serve pricing continues to unfold across Australia.
