Red meat

Cohort studies consistently link higher red meat intake to a modest increase in colorectal cancer and cardiovascular risk, and IARC classifies it as probably carcinogenic to humans. The honest caveat is that nobody can randomise people to eat red meat for twenty years, so this rests on observational data where heavy meat eaters differ from light ones in many other ways. The absolute risk increase per serving is small; the disagreement is over how much of it survives adjustment.

How this list was built

We searched Europe PMC for English-language papers published since 2012 whose title contains “red meat”, kept meta-analyses, systematic reviews, trials and observational studies, because a diet or exposure like this cannot be randomised for long and its outcome evidence lives in cohorts, then ranked them by study design first, then recency and citations. Retracted papers are removed.
