Comprehensive Review of Red Meat Consumption and the Risk of Cancer https://pmc.ncbi.nlm.nih.gov/articles/PMC10577092/ From the abstract: "The evidence is strong for the association between red meat and breast cancer and most gastric cancers.

This looks to me to be a review of food frequency questionnaire studies which are famous for being only good for hypothesis generation, and not great at that. Where their research has been tested by interventional experiments they generally don't survive, for example eggs and cholesterol.

Garbage in; garbage out

Are the rest of them the same? Bring interventional studies if you want to demonstrate causality, if your #1 reference is indicative all you've done is demonstrate you don't know or don't care about the explanatory power of different types of studies, and asking people what they ate in the last 5 years (tick the boxes in the categories on the form) are the least powerful, they don't even demonstrate correlation clearly since they are so low resolution, so prone to healthy food answer bias, and so reliant on human memory of what they ate up to half a decade ago

Anyway people have been doing carnivore or zero carb or zero fibre in modern times for 20 years, if meat was as dangerous as your poor quality studies say the would certainly be studies of the high cancer rate and heart attacks in the carnivore community
