All claims are based on digests, not full reports, and no independent outlets are cited. - Craft 45 of 100, higher is better. The digests are short and lack detail on methodology, impact, or future steps. - Hype 41 of 100, lower is better. Headlines use phrases like 'Study warns' and 'may increase risk' without substantial detail in the digests.

Consuming a diet high in fat can induce lasting changes in intestinal stem cells, according to research. These alterations may elevate the risk of developing tumors. The findings were published in the scientific journal Stem Cell Reports. The study was carried out by researchers at Arizona State University. ## Coverage comparison The digests from all 11 outlets reported that a high-fat diet causes lasting changes in intestinal stem cells and can increase the chance of tumors developing. The study was published in Stem Cell Reports by researchers at Arizona State University. ## What the coverage left out None of the right-rated digests mention the specific journal, Stem Cell Reports, where the study was published. The left-rated and centre-rated digests also do not name the journal. ## Who covered it Shares of the 11 covering outlets with a published leaning rating: - Left: 18% (2) - Centre: 18% (2) - Right: 64% (7) 1 of 12 covering outlets carried no usable leaning rating and were excluded from those percentages. Coverage measured 2026-11-12T20:54:36.035Z. **Coverage watch:** developing. Checked 4 times; 0 checks found a material change. Most recently checked 2026-11-12T21:45:27.572Z. ## How the sides framed it ### Left - The digest from the left-rated Fairfield Sun Times stated that scientists say consuming a high-fat diet leaves lasting changes in intestinal stem cells that can increase the chance of tumors developing. ### Centre - The digests from the centre-rated KPVI and The Anniston Star reported that scientists say consuming a high-fat diet leaves lasting changes in intestinal stem cells that can increase the chance of tumors developing. ### Right - The digests from the right-rated outlets Yonhap News Agency, The Herald Palladium, Webster County Citizen, News-Topic, The Courier-Times, El Mundo, and Owensboro Messenger-Inquirer all reported that scientists say consuming a high-fat diet leaves lasting changes in intestinal stem cells that can increase the chance of tumors developing. The digest from Yonhap News Agency also noted that even after normalizing the diet, traces of these changes remain. **Provisional coverage gap:** left. The watch is not closed, so this is not yet a settled blindspot finding. ## Factuality profile of the covering outlets These are published factuality ratings of the outlets, not a verdict on whether this story or its claims are true. - high: 8 - unknown: 1 - veryHigh: 3 ## Verification scope This page compares coverage and scores the source reporting. It is not a ClaimReview verdict on whether the underlying event or claim is true. ## Original reporting this was written from - [연합뉴스-Yonhap News Agency](https://yna.co.kr/view/AKR20261112099100017) — "High-Fat Diet May Leave Traces on Intestinal Stem Cells and Promote Tumor Growth" - [KPVI](https://kpvi.com/interests/study-warns-eating-fatty-foods-may-increase-colon-cancer-risk/article_bcffe6a5-de66-578d-b8c8-ae51b3ccfba4.html) — Study warns eating fatty foods may increase colon cancer risk - [The Herald Palladium](https://heraldpalladium.com/lifestyles/health/study-warns-eating-fatty-foods-may-increase-colon-cancer-risk/article_10262cd3-2a2b-598d-add7-f346f9fb6173.html) — Study warns eating fatty foods may increase colon cancer risk - [Webster County Citizen](https://webstercountycitizen.com/lifestyles/health/article_04061b86-fd5d-5f3c-92da-506d1dbd2a75.html) — Study warns eating fatty foods may increase colon cancer risk - [The Anniston Star](https://annistonstar.com/features/trending/study-warns-eating-fatty-foods-may-increase-colon-cancer-risk/article_7286d640-b08e-5c8a-964d-e7e43c513821.html) — Study warns eating fatty foods may increase colon cancer risk - [Fairfield Sun Times](https://fairfieldsuntimes.com/arts_and_entertainment/health/study-warns-eating-fatty-foods-may-increase-colon-cancer-risk/article_aa830205-8438-5007-833f-6fbb2a450df0.html) — Study warns eating fatty foods may increase colon cancer risk - [News-Topic](https://newstopicnews.com/lifestyles/health/study-warns-eating-fatty-foods-may-increase-colon-cancer-risk/article_683a4fa4-3d7e-5f95-a53c-bb3420bedbe1.html) — Study warns eating fatty foods may increase colon cancer risk - [The Courier-Times](https://thecouriertimes.com/lifestyles/health/study-warns-eating-fatty-foods-may-increase-colon-cancer-risk/article_2abc9bc9-7d47-58fc-969a-48e82df68a8a.html) — Study warns eating fatty foods may increase colon cancer risk - [News-Herald](https://news-herald.net/lifestyles/health/study-warns-eating-fatty-foods-may-increase-colon-cancer-risk/article_5a341dc7-3667-576a-9a56-35f35a079eef.html) — Study warns eating fatty foods may increase colon cancer risk - [diariomedico.com](https://diariomedico.com/medicina/oncologia/memoria-celulas-madre-posible-nexo-dieta-grasa-cancer-colon.html) — The ‘Memory’ of Stem Cells, a Possible Link Between Fat Diet and Colon Cancer - [El Mundo](https://elmundo.es/salud/2026/11/12/6af5cedd21efa0ac198b45be.html) — Fat-Rich Diets Leave a "Memory" in the Intestine that Favors Colon Cancer - [Owensboro Messenger-Inquirer](https://messenger-inquirer.com/lifestyles/health/study-warns-eating-fatty-foods-may-increase-colon-cancer-risk/article_ac19b6d1-9700-5f56-becb-d5044f5ce0e6.html) — Study warns eating fatty foods may increase colon cancer risk ## Questions **What does a high-fat diet do to intestinal stem cells?** A high-fat diet causes lasting changes in the gene regulatory environment of intestinal stem cells. These alterations persist even after the diet is normalized. **What is the potential consequence of these stem cell changes?** The lasting changes in intestinal stem cells induced by a high-fat diet can increase the chance of tumors developing. This suggests a link between diet and cancer risk. **Who conducted the study on diet and stem cells?** The study was conducted by researchers at Arizona State University. The findings were published in the scientific journal Stem Cell Reports. --- MediaBias News — https://mediabias.news.
