A new study published on March 13, 2025, in JAMA Otolaryngology-Head & Neck Surgery suggests that regularly consuming sugar-sweetened beverages may significantly increase the risk of oral cancer. Given the well-documented health risks of added sugars—including obesity, heart disease, and diabetes—this finding raises new concerns about the impact of sugary drinks on long-term health.
What the Study Found
Researchers analyzed data from over 160,000 women in the Nurses’ Health Study, tracking their beverage consumption and health outcomes for more than 30 years. They found that women who drank at least one sugar-sweetened beverage daily were nearly five times more likely to develop oral cavity cancer. The risk was even higher for those who didn’t smoke or drank alcohol only occasionally.
Sugary drinks included in the study ranged from sodas to sweetened teas and lemonade. The findings are particularly alarming as oral cancer cases are rising, especially among women with no known risk factors such as smoking.
Why This Matters
Although the overall risk of oral cancer remains relatively low, these findings highlight yet another reason to be cautious about excess sugar intake. The study focused only on women, so more research is needed to determine the impact on men and broader populations.
A Cautionary Takeaway
While further studies are necessary, limiting sugary drinks is a wise choice for overall health. Opting for water, herbal teas, or unsweetened alternatives can reduce potential risks and promote better long-term well-being.
