Claim analyzed
“Swallowed chewing gum remains in the human stomach for seven years.”
The Conclusion
Executive Summary
The claim is false. Swallowed chewing gum does not stay in the stomach for seven years; it typically moves through the digestive tract and is excreted within days. “Indigestible” gum base doesn't mean it gets stuck long-term, and major medical sources explicitly debunk the seven-year myth.
Warnings
- Don't confuse “indigestible” with “stays in the stomach”—most indigestible material still passes through normally.
- Citing studies about chewing gum's effect on gastric emptying/transit does not provide evidence that swallowed gum is retained for years.
- Rare medical exceptions (e.g., large amounts swallowed with constipation) can cause blockage, but they are uncommon and still not “seven years in the stomach.”

The Debate
The for and against arguments
The research brief itself shows the “seven years” figure is a widely repeated digestive-timeframe claim tied to the fact that the body cannot digest chewing gum (Source 1, Mayo Clinic; Source 7, Beacon Health System), so it is reasonable to treat the motion's core idea—gum persists rather than being digested—as essentially true in practical terms. Moreover, controlled studies indicate gum chewing does not meaningfully change gastric transit or emptying (Source 4, PubMed; Source 5, PubMed), which is consistent with the notion that gum can remain in the stomach for long periods rather than being rapidly processed like typical food.
Your interpretation of Source 4 (PubMed) and Source 5 (PubMed) commits a fundamental logical error—these studies examined the effects of chewing gum on gastric transit, not swallowed gum retention, and actually demonstrate normal gastric emptying times of 21-23 minutes, directly contradicting any seven-year persistence claim. You're conflating "indigestible" with "permanently retained," when Source 1 (Mayo Clinic) explicitly states that while gum can't be digested, "it moves relatively intact through your digestive system and passes out of your body in your stool," making your "practical equivalence" argument a false dichotomy.
While the research brief contains multiple sources claiming gum passes through the digestive system quickly, these sources fail to provide rigorous scientific evidence or controlled studies specifically tracking gum's journey through the human digestive tract for extended periods, with Source 4 (PubMed) and Source 5 (PubMed) only examining short-term gastric effects rather than long-term retention. The absence of comprehensive longitudinal studies spanning years, combined with the fact that gum's synthetic polymer base is fundamentally indigestible as acknowledged by Source 1 (Mayo Clinic), leaves open the possibility that accumulated gum residue could persist in the digestive system far longer than these sources superficially claim.
Your argument is an argument from ignorance: you treat the lack of “years-long tracking studies” as evidence that seven-year retention is plausible, even though the brief's highest-authority clinical sources explicitly say the opposite—swallowed gum does not stay in the stomach and instead passes through the GI tract and is excreted (Source 1, Mayo Clinic; Source 3, Duke Health; Source 7, Beacon Health System). You also smuggle in a new, unsupported claim about “accumulated gum residue” persisting, but none of the cited evidence shows residue buildup, and the PubMed studies you cite (Source 4; Source 5) actually cut against your insinuation by showing normal gastric transit/emptying rather than any mechanism for prolonged retention.

The Adjudication
How each panelist evaluated the evidence and arguments
The most reliable sources - Mayo Clinic (authority 1.0), McGill University (0.9), Duke Health (0.9), and PubMed studies (0.9) - all explicitly refute the seven-year claim, stating that gum passes through the digestive system within days, not years. The claim is definitively false according to multiple independent, authoritative medical and academic sources that directly address and debunk this specific myth.
The claim asserts gum "remains in the human stomach for seven years," but all high-authority sources (Mayo Clinic, Duke Health, McGill) directly refute this by stating gum passes through the digestive system in 24-48 hours to a few days, not years, and the proponent's argument commits a composition fallacy by conflating "indigestible" with "retained" when the evidence explicitly distinguishes these concepts. The claim is logically refuted: the evidence shows gum transits the GI tract normally despite being indigestible, making the seven-year retention claim false both in its specific timeframe and its underlying premise that gum remains in the stomach.
The claim omits the key context that “indigestible” does not mean “retained”: multiple clinical explainers explicitly state swallowed gum does not stay in the stomach and instead passes through the GI tract and is excreted, typically within days (Mayo Clinic, Source 1; Duke Health, Source 3; McGill OSS, Source 2; KidsHealth, Source 10). With that context restored, the overall impression that gum remains in the stomach for seven years is fundamentally false, and the cited PubMed transit/emptying studies (Sources 4–5) do not support long-term retention framing.
Adjudication Summary
All three axes converge on the same conclusion. Source quality is strong and independent (Mayo Clinic, Duke Health, McGill) and they directly refute the seven-year stomach-retention claim. The logic review identifies the core error: confusing “not digested” with “not transported.” Context review adds that rare obstruction cases exist but don't support years-long stomach residence; the PubMed studies cited are about chewing effects, not swallowed-gum retention.
