Doctors Say PFAS in Canned Sparkling Water Lacks Direct Colon Cancer Proof, as Science Still Evolves

Summary
Two colorectal cancer specialists said there is currently no direct evidence that canned sparkling water causes colorectal cancer, despite social-media claims tying the drinks to “forever chemicals” in packaging.
PFAS concern centers on can linings and plastic packaging rather than carbonation itself; the doctors said some studies found PFAS in popular brands, but typically at levels below current federal advisory limits.
Long-term exposure remains the key uncertainty because PFAS can persist in the body and may disrupt hormones, DNA repair, the intestinal barrier and the gut microbiome—mechanisms that could promote inflammation linked to colorectal cancer.
For now, the doctors advised moderation, more filtered water and varied beverage choices, while emphasizing better-established colorectal cancer risks such as processed meat, alcohol, tobacco, inactivity and missed screening.
