The Urgent Need to Tackle Sugary Drink Consumption in Australia

Australia faces a significant public health challenge with excessive sugar intake, particularly from sugar-sweetened beverages (SSBs). These drinks are the leading source of added sugars in the typical Australian diet, contributing substantially to daily consumption levels that exceed recommended limits. For adolescents aged 12 to 17 years, the average intake from SSBs alone reaches about 4.5 teaspoons of sugar per day, which surpasses one-third of the World Health Organization's recommended maximum of 12 teaspoons for adults. This overconsumption is linked to serious health issues, including dental decay, type 2 diabetes, and cardiovascular disease, making intervention critical especially among young people who are among the highest consumers.

Despite awareness campaigns and voluntary initiatives, progress has been slow. Recent national surveys indicate that while overall SSB consumption has declined slightly over the past decades, teenagers still regularly exceed guidelines, with many consuming them daily. The South Australian Health and Medical Research Institute (SAHMRI), a key player in health research affiliated with institutions like Flinders University and the University of South Australia, has stepped up with compelling evidence supporting a simple yet powerful solution: front-of-pack added sugar warning labels.

SAHMRI's Groundbreaking Qualitative Study

The latest research from SAHMRI's Health Policy Centre, published on May 11, 2026, in BMC Nutrition, delves into how Australian adolescents perceive and react to proposed added sugar warning labels on SSBs. Led by Professor Caroline Miller, Director of the Health Policy Centre, the study provides in-depth insights into teen behaviors and attitudes. SAHMRI, renowned for its translational research bridging academia and policy, conducted this work as part of broader efforts to inform evidence-based nutrition strategies.

Professor Miller emphasized the study's relevance: "We know that too much sugar is harmful to health, causing dental decay and increasing the risk of type 2 diabetes and heart disease. Sugary drinks are the biggest source of added sugar in Australians’ diets and teenagers are among the highest consumers." This qualitative approach allowed researchers to capture nuanced responses that quantitative surveys might miss, highlighting the potential for labels to drive real change.

Methodology: Capturing Authentic Teen Reactions

The study employed semi-structured interviews with 40 adolescents aged 12-17 years from South Australia, a demographically diverse group reflecting typical consumer profiles. Participants were shown various front-of-pack label designs, primarily those displaying the number of teaspoons of added sugar in popular SSB brands. Interviews explored perceptions of the labels' clarity, credibility, and influence on purchase intentions.

This method mirrors real-world shopping scenarios, where quick decisions are made based on visible information. By focusing on interpretive labels like teaspoons—a relatable measure equivalent to household spoons—the research tested designs that translate abstract nutrition data into everyday understanding. Ethical approvals were secured from relevant university human research ethics committees, ensuring participant welfare.

Striking Findings: Teaspoons Labels Reshape Choices

Participants overwhelmingly found the teaspoons-of-added-sugar labels most compelling. Teens frequently remarked that seeing quantities like "16 teaspoons" in a single drink prompted immediate rejection. One 15-year-old stated, "If I saw that, a drink with 16 teaspoons of sugar, I'd put it down and get water." Another noted, "You can't just eat 16 teaspoons of sugar so why would you drink it?" These reactions indicate labels not only inform but deter, encouraging switches to water or low-sugar alternatives.

• High-sugar drinks (over 10 teaspoons) were deemed "shocking" and "unacceptable."
• Labels enhanced perceived health risks, linking sugar to obesity and disease.
• Even moderate-sugar options faced scrutiny, with many opting for zero-sugar varieties.

The study underscores that such labels empower teens to make informed, healthier selections without feeling judged, fostering long-term habit changes.

Beyond Teens: Evidence from Experimental Trials

Complementing the qualitative insights, prior SAHMRI-led experimental studies demonstrate tangible impacts. In a real-choice task, warning labels reduced SSB selection by up to 30%, with combinations of health warnings and sugar content proving most effective. Parents in another trial were less likely to choose sugary snacks for children when pictorial warnings appeared.

These findings align with global evidence, where front-of-pack (FOP) warnings consistently lower unhealthy purchases. For full details on the latest study, visit the BMC Nutrition publication.

Shortcomings of Australia's Health Star Rating System

Australia's voluntary Health Star Rating (HSR), recently mandated in February 2026, scores products out of five stars but fails to explicitly highlight added sugars. Critics, including SAHMRI researchers, argue it inadequately distinguishes added from natural sugars, allowing high-sugar juices to score well. Studies show 63% of new HSR-displaying products contain added sugars, misleading consumers.

HSR's algorithm, co-developed with industry, has loopholes penalizing sugar less severely than fats, prompting calls for reform. Jane Martin from Food for Health Alliance noted, "FSANZ's decision to abandon mandatory added sugar labelling is a backward step."

Global Lessons: Success of FOP Warning Labels

Over 30 countries, including Chile and Mexico, mandate FOP warnings, achieving 20-30% drops in sugary product purchases. In Chile, black octagons on high-sugar items reduced teen consumption by 25%. Australia's delay contrasts with this, despite 82% public support for teaspoon labels per Cancer Council surveys.

Stakeholder Views: Health Advocates vs Industry

Health organizations like SAHMRI and Cancer Council champion labels for empowering consumers. Industry groups express concerns over "alarmist" designs potentially stigmatizing products, advocating HSR enhancements instead. Policymakers face pressure post-FSANZ's March 2026 abandonment of added sugar mandates amid mandatory HSR rollout.

Balanced reform could integrate teaspoon info into HSR, satisfying both evidence and feasibility.

Policy Pathways Forward for Australia

To curb SSB intake, experts recommend mandatory FOP added sugar labels, marketing restrictions on kids' ads, and pricing incentives like sugar taxes (supported by 60%+ Australians). SAHMRI advocates prioritizing beverages, where labels yield quickest wins. With obesity rates at 30% among teens, timely action could avert billions in healthcare costs.

Opportunities in Nutrition Research Careers

SAHMRI exemplifies higher education's role in public health, partnering with universities for impactful studies. Aspiring researchers can pursue roles in health policy centers, contributing to labeling reforms.

Looking Ahead: A Healthier Future for Aussie Youth

SAHMRI's research illuminates a straightforward path: added sugar warning labels can transform teen choices, curbing a key obesity driver. As Australia refines HSR and considers FOP innovations, evidence from institutions like SAHMRI will guide equitable, effective policies. Empowering youth with clear info promises lasting health gains.
