A new study published in the journal Nutrients reveals that while children and parents do notice sugar warning labels on beverages, these labels have only a modest effect on actual drink choices—especially among kids, who continue to prefer flavored milk even after seeing the warnings.
Study Overview
Researchers surveyed 1,229 Australian children aged 4 to 11 and their parents. Participants were asked to choose beverages from an online vending machine, first without any warning labels and then with randomly assigned labels on sugary drinks. The drinks included options such as flavored milk, 100% fruit juice, fruit drinks, plain milk, bottled water, and soft drinks (with sugar or artificial sweeteners).
Four types of labels were tested:
-
A text warning about tooth decay from high sugar
-
A picture of tooth decay with a high sugar warning
-
A label showing the number of teaspoons of sugar
-
The Health Star Rating (HSR), a government-backed label showing the drink’s overall healthiness
Key Findings
-
Recall and Recognition: Only about half of the children and two-thirds of parents remembered seeing any labels at all. Of those, children were more likely than parents to recall the labels accurately.
-
Impact on Choices: The labels had only a small impact on what children chose to drink. Flavored milk remained the top pick among kids, regardless of the warnings. The “teaspoons of sugar” label had the strongest effect, nudging some children toward water, but most still stuck with their original choices.
-
Parental Choices: Parents were more likely to choose water or artificially sweetened drinks, but soft drinks remained popular. The HSR label had a slightly greater influence on parents, leading to healthier choices in some cases.
-
Emotional Response: The tooth decay picture label was most effective at worrying older children (ages 8-11), while text warnings and sugar teaspoon labels had more impact on younger kids (ages 4-7).
Why Don’t Labels Work Better?
The study suggests that while warning labels can grab attention, their ability to change behavior is limited. Many children and parents simply didn’t notice or remember the labels, and the emotional or cognitive impact was not strong enough to override established preferences—especially for flavored milk.
The researchers note that the HSR, while helpful for adults, may not be as effective for children because it appears on all drinks and doesn’t create a strong emotional reaction.
Implications for Public Health
The findings highlight the need for more effective labeling and broader interventions to help families make healthier drink choices. Clear, emotionally engaging warnings may help, but they are unlikely to be a silver bullet. The study also points out that real-world behavior may differ from simulated online scenarios, and long-term follow-up is needed to assess the true impact of labeling.
Conclusion
Warning labels alone are not enough to steer children away from sugary drinks like flavored milk. More comprehensive strategies—including better label design and stronger regulations—are needed to help families make healthier choices.
