A new study points to a surprising contributor to rising oral cancer cases: sugary beverages. Researchers analyzed dietary records from about 162,600 women over three decades and found that those who drink one or more sugary drinks daily had nearly five times the risk of developing oral cancer compared with those who rarely drink them. Among non-smokers or light drinkers, the risk remained elevated at about five-and-a-half times for daily sugary drink consumers.
The study’s lead authors caution that the findings come with limitations. The population studied was exclusively women, and the number of cancer cases was relatively small. Still, the results raise important questions about how everyday dietary patterns influence oral health, beyond the well-known risks of tobacco, alcohol, and HPV. Researchers also call for investigating whether artificial sweeteners in diet beverages carry similar concerns.
For Thailand, where oral cancer remains a significant health burden and screening programs vary by region, these findings underscore the importance of public health messaging on healthy beverage choices. Traditional Thai resilience and moderation—values embedded in local health practices—can support messaging that encourages reducing sugary drink intake without stigmatizing everyday habits.
Public health experts here emphasize practical steps. Promoting water and unsweetened herbal teas, which align with Thai culture and taste preferences, can help reduce sugar consumption. Health campaigns could also focus on early detection and awareness, encouraging regular dental check-ups and conversations about risk factors with healthcare providers.
Looking ahead, more research is needed to understand the full scope of risks, including whether zero-calorie sweetened drinks pose similar concerns. In the meantime, Thai readers can take a tangible step toward prevention by favoring hydration through natural beverages and by moderating sugar intake as part of a broader lifestyle approach to healthy living.
Data from international health research suggests that diet-related cancer risks are evolving. Thailand’s public health strategy should adapt by integrating nutrition education with screening programs, ensuring communities understand and access practical, culturally appropriate guidance.
