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.

Questions about this coverage

How did the left and right cover High-fat diet alters stem cells, may raise tumor risk?
Of the 10 outlets on this story carrying a published leaning rating, 10% are rated left, 20% are rated centre, 70% are rated right. Those percentages are shares of the rated outlets, not of every outlet that ran it, which was 11. The sections above set out what each side emphasised, in its own terms.
Is High-fat diet alters stem cells, may raise tumor risk left or right?
Too few of the outlets on this story carry a published leaning rating to say. 10 of them do, and this site does not characterise a field under 12: at that size one newsroom filing moves the share by ten points. The percentages above are the count as it stands.
Is the coverage of High-fat diet alters stem cells, may raise tumor risk biased?
High-fat diet alters stem cells, may raise tumor risk is one event reported by 11 outlets, and this page does not rate the story as biased or unbiased. What it publishes is the spread: which outlets ran it, where named rating organisations place each of them on the spectrum, and what each side chose to lead with. A leaning rating describes an outlet's record over time, not this article, and the two should not be run together.
Which side is not reporting High-fat diet alters stem cells, may raise tumor risk?
When we first saw this story, outlets rated left had barely covered it. Coverage accretes for hours after an event, so that is where to look rather than a verdict — the split above is the current count, and it is the one to read.
Which outlets covered High-fat diet alters stem cells, may raise tumor risk?
11 that we know of, every one of them listed further up this page with a link to its own report and to what we hold on the publisher. Nothing here is a summary of somebody else's summary: the outlets are named so the original reporting can be read.
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.
