Doctors Urge Moderation on Canned Sparkling Water as PFAS Levels Stay Below Federal Limits

Summary
Two colorectal cancer specialists said canned sparkling water is not currently considered a significant PFAS source, but advised moderation because any colorectal-cancer link remains unproven and under study.
PFAS concerns center on can linings and other packaging—not carbonation itself—and some studies have detected the chemicals in sparkling water brands, generally at levels below current federal advisory limits.
The doctors said PFAS could theoretically raise cancer risk over long exposure by disrupting hormones, increasing oxidative stress, impairing DNA repair and fueling gut inflammation tied to colorectal cancer.
Until longer-term research clarifies the risk, they recommend filtered water as the safest hydration choice, varied beverage habits, and focusing on established colorectal-cancer risks such as processed meat, alcohol, smoking and missed screening.
