Red Meat Does NOT Cause Cancer!

This solo episode by Dr. Anthony Chaffee dismantles the widespread belief that red meat causes cancer by exposing the flawed methodology behind the 2015 IARC report. The analysis reveals how researchers cherry-picked studies showing only an 18% increased risk association - far below the 200% threshold required for epidemiological validity - while ignoring hundreds of higher-quality studies that showed no correlation between meat and cancer.

Dr. Anthony Chaffee highlights the conflicts of interest within the IARC working group, including members with vegan beliefs and religious anti-meat biases from the 7th Day Adventist church. He contrasts this with recent research from the University of Washington, which analyzed over 800 studies and found weak to no evidence linking processed meat to cancer, and absolutely no connection between unprocessed red meat and any disease, including cancer or cardiovascular conditions.

Key Takeaways

  • The 2015 IARC report claiming red meat causes cancer was based on only an 18% increased risk association - well below the 200% threshold needed for epidemiological validity, making it statistically insignificant background noise
  • IARC researchers cherry-picked studies while discarding hundreds of higher-quality studies that showed no correlation between meat and cancer, as publicly criticized by committee member Dr. David Clerfeld
  • University of Washington research analyzing over 800 studies found weak to no evidence that processed meat causes cancer and absolutely no link between unprocessed red meat and any disease including cancer, heart disease, or diabetes
  • Many IARC committee members had undisclosed conflicts of interest including vegan beliefs and 7th Day Adventist religious anti-meat doctrine, which considers meat consumption morally problematic
  • Red Meat and Cancer Claims: Epidemiology Problems
  • IARC 2015 Decision Challenged by Committee Members
  • University of Washington Study: 800 Studies Show No Cancer Link

Red meat does not cause cancer. What we have to remember about the idea that red meat causes cancer is that it comes from the 2015 IARC working group through the WH where they took a couple dozen studies that showed a very weak correlation between processed meat and colurectal cancer. Really only an 18% increased risk association. This was done by epidemiology looking at food frequency questionnaires asking people try to try to remember what they've eaten in the last two to four years sometimes and trying to get valuable information out of that which of course is impossible because that's wholly inaccurate. They go one step further in making this more inaccurate by saying processed food is basically any junk food that may contain meat such as hamburgers along with fries and a drink or pizza, lasagna, sandwiches generally. And this is literally what they are calling meat or processed meat. Meat makes up a very small proportion of the calories. And even then, it only showed an 18% increased risk association. Now, that's significant because if you can't get a 200% increased risk association, it is considered not valid in an epidemiological sense. It's just considered background noise because there are so many of these confounding factors that may mix things up. Also, they didn't correct for people that eat more meat and processed meat like junk food and pizza tend to smoke more, tend to drink more, and do other sorts of dangerous activities for their health. This decision has even been publicly challenged by some of the people that were on the working group committee in 2015 with the ARC, such as Dr. Dr. David Clerfeld, who's an extremely esteemed long-term doctor and researcher for the USDA, long-term nutritional researcher, professor of medicine, and has over 200 peer-reviewed publications to his name, as well as book chapters. He has stated publicly numerous times that the 2015 ARC decision on meat and red meat in particular was the most frustrating professional experience of his life. And this is because he watched them throw out hundreds of good quality studies that showed no correlation whatsoever between even processed meat and cancer, but especially not unprocessed red meat and cancer of any form. and instead chose the few studies that showed a very weak correlation that again did not reach the threshold of 200% increased risk association and then use that to say this is definitive proof that meat causes cancer and unprocessed red meat may cause cancer. He also pointed out that many of these board members that pushed for those studies to be thrown out and the others held actually had quite a lot of conflicts of interest such as they were vegans, vegetarians or members of the 7th day Adventist church which is known for being religiously anti-meat because they feel that it causes lustful feelings, masturbation and fornication. That's not me saying this. You can look up their own charter and their own writings for yourself. They also have many financial ties and conflicts of interest. If you want to look at complete data and not the cherrypicked ones that the ARC used, you can look at a recent publication from the University of Washington in Seattle, which is the number one medical school in America most years and one of the top research institutions in the world. They published a paper in the prestigious publication nature called the health effects associated with consumption of unprocessed red meat a burden of proof study. In this they look at over 800 studies that the ARC threw to the side because they didn't want to look at that were much higher quality evidence had less confounding factors and found weak to no evidence that even processed meat had any association whatsoever with colorectile cancer or any other form of cancer or any disease at all including cardiovascular disease or diabetes. and no link whatsoever between unprocessed red meat and any of these conditions including cancer, heart disease, etc. So really the claims against meat causing cancer really just amount to bias and cherrypicking and not real datadriven science.
