1. Putting anti-meat studies into context
Vegans use appeals to authority or observational (non-causal) studies with tiny risk factors to
vilify animal products. Respectable epidemiologists outside of nutrition typically reject these[1]
because they don't even reach the minimum threshold to justify a hypothesis and might
compromise public health[2]. The study findings are usually accompanied by countless
paradoxes such as meat being associated with positive health outcomes in Asian cohorts[3]:
1) Vegans like to say that meat causes cancer by citing the WHO's IARC[4]. But the report
actually says there's no evaluation on poultry/fish and that red meat has not been established as
a cause of cancer. More importantly, Gordon Guyatt (founder of evidence-based medicine,
pescetarian) criticized them[5] for misleading the public and drawing conclusions from
cherry-picked epidemiology[6] (they chose only 56 studies out of the supposed 800+). A third of
the committee voting against meat were vegetarians[7]. Before the report was released, 23
cancer experts from eight countries looked at the same data[8] and concluded that the evidence
is inconsistent and unclear.
2) The idea that dietary raised cholesterol causes heart disease has never been proven[9].
3) Here's a compilation[10] of large, government-funded clinical trials to oppose the claims
made to blame meat and saturated fat for diabetes, cancer or CVD. Note that these have been
ignored WHO and guidelines.
4) Much of the anti-meat push is coming from biased institutions like Adventist universities or
Harvard School of Public Health who typically don't disclose their conflicts of interest. The latter
conducted bribed studies for the sugar industry[11] and was chaired by a highly influential
supporter of vegetarianism[12] for 26 years. He published hundreds of epidemiological
anti-meat papers (e.g. the Nurses' Health Studies), tried to censor[13].
