This is usually not considered reliable. They also don't look if there could be other foods causing the cancer markers, sugar for example. High protein+cheap carbs are more likly to cause cancer afaik, So these ppl are probably also eating tons of white bread and drink energy drinks or whatever. Dietary information in the participating cohorts was collected by self-reported approaches: 26 cohorts used food frequency questionnaires, three used dietary history, and two used dietary records (appendix p 2). Three primary exposure variables were determined by calculating total consumption levels of unprocessed red meat (eg, beef, pork, lamb, and veal), processed meat (eg, bacon, ham, sausage, and hot dog), and poultry (eg, chicken, turkey, duck, and goose). Chicken and poultry aren't red meat, they're white meat? AND: Consumption levels of other food groups were considered as covariates. The CoVariates: We considered the following covariates as potential confounding factors (for cohort-specific details, see appendix p 8) according to published literature and biological plausibility: sociodemographic characteristics (age, sex, ethnicity, and education level), health and lifestyle behaviours (smoking, drinking alcohol, and physical activity), dietary information (consumption of fruits, vegetables, fish, dairy, legumes, soy, nuts and seeds, eggs, cereal products, whole grains, potatoes, fibre, sugar-sweetened beverages, coffee, tea, and cooking fat and total energy intake), BMI, comorbidities at baseline (hypertension, dyslipidaemia, myocardial infarction, stroke, or cancer), and family history of any type of diabetes. The three types of meat were mutually adjusted for each other. At the end, they recommend to eat more poultry, and less red meat. That doesn't sit right with me. Industrially raised poultry is high in omega 6 which is inflamatory than just beef. To me it's pretty unfair to throw ham into the same category as beef-steak and then recomend to eat more chicken.
