“Does Red Meat Cause Cancer?”

Countless people have tried to pin cancer on red meat, but what’s the truth?

It was a reason why Dr. Layne Norton, a very smart PhD who is not a slouch when it comes to nutrition and physiology, said a carnivore diet is a stupid idea – yet i did it nonetheless.

One of the biggest reasons this worry exists is thanks to a 2015 paper published by the WHO.

Here’s the tweetstorm version of it (and under my saved instagram highlights under “cancer” i talk a bit about this):

This paper the WHO released was based on weak epidemiology. They cherry picked studies and omitted those that didn’t fit within their conclusions. The relative risk finding of 1.7, nonetheless, is still so weak that anything under 2.0 is known to be unreliable.

This paper was based on bias, bad data, and ulterior motives.

But then Steven asked a great question…

To me it’s a strange thought that modern cancers and diseases are attempted to be pinned on meat – a food that we are literally designed to eat.

Hope this puts your mind to rest if you were worried about red meat causing cancer. Nothing to worry about.

  1. Hey Kevin! Great content here. I’ve just started carnivore a little over two weeks ago to see if it helps my UC and I’m feeling amazing with each passing day in the energy and mental clarity department (still adjusting restroom-wise but that will likely take some more time). Related to this post’s topic, the thing I’m concerned with when shifting to this lifestyle is the potential cancer risk due to the activation of IGF-1 and mTOR. Have you studied that pathway at all and what is your take on it? Should I be worried?

  2. Great blog! I’ve been a big proponent of organic grassfed/pastured meats for years, but was alarmed to discover some of the research on Neu5gc (found in almost all non-human mammal meat and dairy except butter/ghee/tallow/lard; non-endogenous and inflammatory to humans—and found highly concentrated in human tumors).

    Until I know more, I’ve restricted my animal products to organic pastured poultry/eggs, wild Alaskan/North Atlantic seafood/shellfish, organic grassfed ghee/tallow/lard, and am considering the possibility that the evolutionary switch to animal protein diets actually centered around coastal seafood rather than land mammals.

    You’ve got some great takes, and strong arguments for avoiding inflammation-causing foods and for eating lots of animal protein. What are your thoughts?

    1. Thanks so much!

      I’ve studied Neu5gc a bit – here are my thoughts – I had my blood work done (https://www.kevinstock.io/health/carnivore-diet-blood-work/) after eating well over 1,000 lbs of red meat in 2018. If Neu5gc caused an inflammatory immune response my hs-CRP would very likely be elevated – but my hs-CRP was below the detectable limit. Just no signs of systemic inflammation. Sometimes things in theory and test tubes are different than reality, and I think Neu5gc is likely one of those things.
