We already know sugary drinks aren’t doing our bodies any favors—but now, there’s another reason to cut back. A new study published in JAMA Otolaryngology – Head & Neck Surgery has found a link between sugar-sweetened beverages and a higher risk of oral cavity cancer (OCC), particularly in women.
Researchers analyzed data from over 160,000 women and discovered that those who drank at least one sugary beverage per week had nearly five times the risk of developing OCC compared to those who consumed less than one per month. Even among non-smokers and non-drinkers, that risk jumped to over fivefold with daily consumption.
OCC includes cancers of the tongue, gums, and tonsils. While smoking and alcohol have long been considered primary risk factors, this study suggests diet, specifically sugary drinks, may also play a role. Experts believe high sugar intake may contribute to chronic inflammation, disrupt the oral microbiome, and promote conditions where abnormal cells can thrive. The acidity of soda and other sweetened drinks may also damage the mouth’s lining, increasing vulnerability.
While this research doesn’t prove sugary drinks cause cancer, it identifies them as a potential modifiable risk factor—something you can change.
If you’re looking to cut back, try replacing soda and sugary teas with healthier alternatives like:
- Sparkling water with lemon or berries
- Herbal iced teas (unsweetened)
- Infused water with cucumber or mint
- Coconut water (no added sugar)
Even small changes can reduce inflammation, support oral health, and improve overall wellness. And remember: regular dental checkups and being alert to changes in your mouth are key to catching problems early.
