There is no small amount of epidemiological data that supports that idea, with a mechanism that iron intake is at least one contributing parameter.
Just out of curiosity are you on the TRT train?
not at all. i am from germany and TRT is no topic here.
i eat pretty average. i am not paleo, low carber or vegan or whatever.
i eat meat maybe 4 times a week and just try to avoid processed garbage.
and this epidemiological data you talking about is the thing i think needs more analysis.
after the last red meat alert i tried to research the real numbers of said data and all i could find was some risk misinformation from the WHO and fearmongers of big newspapers who jump on every alert they can find.
i think the last big news came from a british study and a british doctor who actually can read studies and the relevant conclusions brought up that the numbers were not dangerous at all, just slightly increased due to an also occuring decline with health conditions triggered by adipositas and less exercise in populations with lower education.
i actually studied sociology and i took part in creating studies and analyzing their results so i know how tweaked and colored and simply unplausible the conclusions can be if the wrong people just want a shocking and new and good selling "fact" which in reality is just a mild variance from the average. somebody needs to pay for studies and most of the time the people who pay have a result they like to see.
a lot of people just act like meat is per se carcinogenic, heart wrecking and diabetes making evil stuff. and i think this is not true. a lot of these studies never mention the constraints of the life styles of people who develop colon cancer or the different qualitiy of your meat sources, for example. at the end you have a news reporter who needs drama.
people act like eating meat is like smoking cigarettes.
sorry for my grammar. i am not that fluent in writing english.
i hope you got my point.
p.s i don't want to start a big discussion here. i just don't hink meat is a more dangerous part of our nutrition than the normal other stuff we consume in industrial countries on a daily basis. i don't think an all meat diet is an optimal way of nutrition. but i think meat doesn't produce more cancer than mass produced eggs or milk, candy or even veggies.
