Swallowed gum passes through the digestive tract normally.

1. Pass Title matches the evidence

   Title 'Swallowed gum passes through the digestive tract normally' matches the evidence (clinical explanations and case series) and the False finding.

2. Pass No obvious contradictions

   Finding False, answer, and conclusion (contradicted with high confidence) agree; key points and rare-bezoar caveat are consistent.

3. Pass Plausible justification

   Conclusion gives a clear reason: gum base is indigestible but normally transits, and the only documented retention cases involve large or repeated ingestion.

4. Pass Sources are relevant

   Sources (McGill, Cleveland Clinic, Milov et al. Pediatrics, Mayo Clinic) are by name and description plausibly on topic for gum digestion and bezoars.

5. Pass Common questions answered

   Three common questions are present and each response directly addresses its question.

Coverage: Read the full article payload; sources judged by name/title/description/role only, per First Look's rules; no source snapshots read.

1. Concern (minor) Context is complete

   Add the typical transit range the sources give (McGill: 24-48 hours; Cleveland Clinic: about 40 hours), with the variation caveat, so readers learn what normally happens.

   The article covers the key context: digestion vs. transit, the rare bezoar risk, and that the claim concerns occasional swallowing. But it gives readers no sense of how long gum actually takes to pass, saying only 'No exact transit time applies universally'. Its own sources are specific: McGill says 'Gum, like most other undigested foods, will pass through you within 24-48 hours' and gives average transit as 'a little over 24 hours'; Cleveland says 'about 40 hours later in your stool' and 'not ... seven years or even seven days'. Stating the typical range of a day or two, with the caveat, would show how far off the seven-year claim is. The overall impression does not change, so this is Minor. Confidence: High.

2. Pass Central claims are accurate

   Article summary: swallowed gum base is not digested but normally passes through the GI tract rather than staying seven years; large or habitual swallowing can rarely cause bezoars/obstruction, especially in children. Claim ratings: 1. 'Gum base resists digestion' - True. Cleveland: gum base is 'nondigestible'; Mayo: 'your body can't digest chewing gum'; McGill: gum 'is not metabolized, broken down, or absorbed like most food'. 2. 'Swallowed gum normally passes through like other undigested material' - True. Mayo: it 'moves relatively intact through your digestive system and passes out of your body in your stool'; McGill compares it to corn, seeds and fiber; Cleveland: 'it'll come out about 40 hours later'. 3. Finding 'False' for seven-year retention - True. All three readable sources reject it explicitly (Mayo: 'this isn't true'; Cleveland: 'No'; McGill: 'unfounded'). 4. 'Rare obstructions involve larger or repeated ingestion, especially in children' - True. Mayo: 'On very rare occasions, large amounts of swallowed gum combined with constipation have blocked intestines in children'; McGill and Cleveland say the same. 5. Milov et al. reported three pediatric bezoar cases (Nemours, 1998) - Unverifiable from the tool (403, no archive); consistent with my own knowledge of that Pediatrics paper and peripheral to the finding. 6. Evidence years 2022 and 2025 match the Cleveland (April 25, 2022) and Mayo (May 14, 2025) pages; McGill 2019 matches (7 Nov 2019). No central claim is less than True. Confidence: High.

3. Pass Claims are supported and labeled

   Each major claim maps to cited evidence: indigestibility and normal passage to gum-digestion-explanation (Cleveland, Mayo) and gum-seven-year-origin-check (McGill); the rare-obstruction caveat to gum-bezoar-cases (Milov) and corroborated by all three readable sources. The article separates fact from inference: it says 'No exact transit time applies universally' and does not overclaim beyond its sources. The Milov source could not be read, but the claims it supports are also stated by Mayo ('large amounts of swallowed gum combined with constipation have blocked intestines in children') and McGill. Confidence: High.

4. Pass Sourcing is strong and transparent

   Sources are two major clinical institutions (Mayo Clinic staff page with references to a pediatric GI textbook and NIDDK; Cleveland Clinic with a registered dietitian), a university science office piece written by a physician (McGill OSS, Christopher Labos MD), and a peer-reviewed case series in Pediatrics. For a well-established physiology question, high-quality secondary clinical guidance is appropriate; no partisan or anonymous sourcing. The article states which source supports which evidence item. The primary case series is unreadable to the tool (403, no archive), which limits verification of its specifics but not the central finding. Confidence: High.

5. Pass Framing is fair and neutral

   The claim is stated as it circulates ('remains in the stomach or digestive tract for seven years'), matching the folklore wording in Mayo and Cleveland. The article does not ridicule believers; objections such as 'If the body cannot digest gum base, it must stay inside' are answered with the digestion-vs-transit distinction. It keeps the safety caveat rather than overstating harmlessness, in line with all sources. Confidence: High.

6. Pass Uncertainty is stated

   High confidence fits: three independent clinical/science sources agree, and the evidence is not contested. The article states its limits: patient guidance 'do[es] not predict an exact transit time for every person'; a 'three-case report cannot estimate population incidence'; the McGill piece 'is a science communication article rather than a prospective transit-time study'. It notes that no external specialist review has been recorded. No conflicting evidence was found that would need weighing. Confidence: High.

Coverage: Read the full article payload and three of four cited sources: McGill OSS 'Gum and the 7 Year Myth' (live, 2019, Labos), Cleveland Clinic 'What Happens if You Swallow Gum?' (live, April 25, 2022), and Mayo Clinic 'Swallowing gum: Is it harmful?' (Wayback capture, May 14, 2025). The Milov et al. Pediatrics 1998 case series (gum-source-milov) could not be read: HTTP 403 on the live page and no Wayback capture. Its details (three pediatric cases, Nemours) were therefore not verified against the source; the rare-obstruction point it supports is independently corroborated by the other three sources. No live web search used.

1. Pass Rates the real claim

   The claim 'If swallowed, chewing gum remains in the stomach or digestive tract for seven years' matches how the folklore circulates (gum 'stays in your stomach for seven years'); widening to 'digestive tract' neither weakens nor strengthens it. Context limits scope to 'occasional accidental swallowing', which is what someone repeating the claim means, and the conclusion stays within it while separately flagging large or habitual ingestion. No strawman. I would rate the same claim.

2. Pass Rating follows from the evidence

   Before reading the verdict I would choose False: e1 says the body 'does not break down gum base' but 'the swallowed material normally continues through the tract and is eliminated'; e2 finds no basis for seven-year retention; e3 shows only rare obstruction after 'repeated or substantial gum swallowing', which does not support routine seven-year retention. The article's finding is False and the answer ('normally passes through like other undigested material') agrees with it.

3. Pass Confidence matches the evidence

   High confidence is reasonable: the claim requires an implausible retention mechanism, and two clinical institutions plus a university science office agree, with the only counter-case (bezoars) explained as large or repeated ingestion. The title 'Swallowed gum passes through the digestive tract normally' and summary claim no more than that ('normally', 'rare exception'). Limitations that matter are stated: no universal transit time, the case series 'cannot estimate population incidence', McGill 'is a science communication article rather than a prospective transit-time study'. None of the evidence is a direct transit measurement, but for a consensus physiology question this does not lower my confidence below High.

4. Pass Strongest objections answered

   Strongest objections I would raise: (1) indigestible means it must stay; (2) documented gum bezoars show gum can be retained; (3) people with motility disorders or strictures might retain it. The article answers (1) with the digestion-versus-transit distinction, (2) with the case series showing accumulation only after repeated or large ingestion, and puts (3) out of scope in context ('an existing narrowing of the gastrointestinal tract'). The responses rest on the evidence, not on dismissal.

5. Pass Evidence is independent

   e1 (Cleveland Clinic, 2022; Mayo Clinic, 2025), e2 (McGill OSS, 2019) and e3 (Milov et al., Nemours, 1998) cite different sources and institutions. All three explanation sources rest on general digestive physiology, not a shared dataset or study, and none is presented as deriving from another. The case series is a separate clinical line that addresses only the exception. No dependence problem.

Coverage: Read the full article payload: claim, finding, answer, confidence, title, summary, context, conclusion, three evidence items with methods, institutions, years and limitations, three objections with responses, five method steps, and four sources. Per the Skeptic's instructions, source snapshots were not read; evidence was taken as stated.

1. Concern (minor) Verdict fields agree and stand alone

   Change "contradicted with high confidence" to "false with high confidence" in the conclusion's first sentence to match the current False label.

   Verdict reads: FactHub rates the claim 'If swallowed, chewing gum remains in the stomach or digestive tract for seven years.' False (High confidence): 'Gum base resists digestion, but swallowed gum normally passes through like other undigested material.' The claim is worded as it circulates and the answer stands alone. However, the changelog records the label changed from 'Contradicted' to False, yet the conclusion still opens 'The seven-year claim is contradicted with high confidence'. Rule broken: title, claim, finding, answer, summary and conclusion must express the same conclusion 'in the current label's terms'; stale wording from an earlier label is Minor.

2. Concern (minor) Each section does its job

   Make the summary one sentence, e.g. "Clinical explanations agree swallowed gum normally passes; case reports show rare obstruction only after large or habitual swallowing."

   Rule: 'summary is one sentence naming the strongest independent lines of evidence.' The summary is two sentences ('Medical explanations agree ... seven years.' and 'Pediatric case reports establish ... obstruction.'). Also, keyPoint 5 ('...so this article does not promise a fixed number of hours or days') is a scope statement about the article rather than what the evidence establishes; it belongs in the editorialNote. Other fields comply: context is a short framing paragraph; the conclusion synthesizes mechanism, the bezoar limitation and confidence; the editorialNote states scope, caveats and that no external specialist review is recorded. Minor: content in the wrong field or form, no restated-only conclusion.

   About conclusion The finding

3. Concern (minor) Consistent house style

   Explain "bezoar" at first use, e.g. "a bezoar (a compacted mass of indigestible material in the gut)".

   Rule: 'Technical terms a general reader would not know are explained at first use.' 'Bezoar' appears in the summary ('contribute to a bezoar or obstruction'), keyPoints, conclusion ('The rare bezoar cases') and evidence gum-bezoar-cases ('chewing-gum bezoar cases') but is never defined. Otherwise spelling (American), names (Cleveland Clinic, Mayo Clinic, McGill University Office for Science and Society, Nemours Children's Clinic) and terms are consistent, and no drafting text remains.

4. Pass Title states the finding

   Title 'Swallowed gum passes through the digestive tract normally.' states the verified finding in positive form, names the subject, does not repeat the myth, and resolves the claim for a title-only reader (rule: lead with what is true). seoTitle 'Does Swallowed Gum Stay for Seven Years? No' uses search wording and states the finding ('No'), which the rule allows.

5. Pass Limitations are specific

   Each limitation is specific to its item: patient explanations 'do not predict an exact transit time for every person or exclude complications in unusual circumstances'; McGill 'is a science communication article rather than a prospective transit-time study'; the case series 'cannot estimate population incidence' and selected severe cases 'do not describe what normally happens'. None is boilerplate.

6. Pass Tone is measured and respectful

   Language is measured ('contradicted with high confidence by converging clinical explanations', 'normally', 'rare'). No absolutes such as 'proves' or 'impossible'. Objections are answered briefly and with evidence (e.g. 'Digestion and transit are different processes'), without ridicule of people who hold the claim.

7. Pass Readers can verify it

   Every source has a meaningful role label ('Myth and mechanism review', 'Clinical patient guidance', 'Pediatric case evidence'), a full title, a URL anchor, and a description of why it was chosen. The peer-reviewed case series is anchored to its Pediatrics publisher page and repeated under resources. Method steps cover claim definition (step 1), multiple independent sources (step 2), sources reviewed (step 2), and recorded limits (step 4).
