We can't find evidence that holds up here. Proponents are reasoning from mechanism or analogy rather than direct human data, and the most credible skeptics raise objections we can't dismiss.
so this whole decision is based on one statistically significant thing out of 14 and in that one study they said the increased risk due to red meat intake occurred only at lower legume intakes and higher body mass so these are people who are more obese and had more tendency toward diabetes those were the only people in whom red meat was associated with a problem with higher incidence of colon cancer
Every Sunday: the week’s new conflicts and verdict changes — and nothing else.
Native comments, Twitter mentions, and Reddit threads about this claim — surfaced together so the conversation isn't fragmented across platforms.
Bookmarking — the dossier-vs-overview split is the right call. Most of the time I want overview; sometimes I want receipts.

the iarc i believe is a whole committee that got together in 2015 the secret location in france they had over 400 studies to consider and they threw all of the interventional studies out they only included 14 studies in that assessment this is the assessment that people go on when they say that red meat is a class 2 a or b carcinogen whether you're thinking about non-processed or processed red meat and they threw out all of the studies except for 14.

this was a self-selected committee members could appoint themselves and as David says in the paper most of the members of this committee had spent their whole careers studying the relationship between meat and other foods and cancer suggesting that there may be some intrinsic bias with these researchers in general from the very beginning the researchers looked at over 800 articles for inclusion in their summary report and excluded all of them but 14 observational studies this means 700 and 86 studies were excluded they don't give any explanation of why and this included all of the Interventional animal studies this included the two Interventional studies that I detailed previously which showed no change in cancer risk with decreased red meat so these researchers excluded Interventional studies in humans they excluded animal studies with interventions and they looked at 14 studies all of which were observational in the end they declared that red meat was a class 2A carcinogen
let me tell you the story of the iarc working group from 2015.
the IC I believe is a who committee that got together in 2015 the secret location in France they had over 400 studies to consider and they threw all of the Interventional studies out they only included 14 studies in that assessment this is the assessment that people go on when they say that red meat is a Class 2 A or B carcinogen whether you're thinking about nonprocessed or processed red meat and they threw out all of the studies except for 14 of the 14 studies every single one was epidemiology they threw out all the Interventional studies they threw out all the uh animal studies that did not show any harm with red meat in animals and even animal studies that showed that giving bacon to rats improved their GI cancers they threw out all those studies in their consideration they used 14 epidemiology studies in their final decision by the wh IC committee
They made that decision based on over 400 studies, but only decided to include 14 in their decision. Of those 14, all of them are observational. They included no interventional studies. The majority of those 14 studies show no association between red meat and cancer.
