Red Flag Origin

Definition	Regular processed-meat consumption ≥50 g/day per WCRF/IARC threshold. IARC Monograph 114 (2015) classified processed meat as Group 1 carcinogen for colorectal cancer (sufficient evidence). Each 50 g/day of processed meat increases CRC risk by ~18% (meta-analyzed RR ~1.18; WCRF/AICR convincing-evidence rating). Processed meat = sausages, ham, bacon, salami, cured/smoked/salted/preserved meat. Red meat (Group 2A per IARC, probable carcinogen) is a separate but overlapping concern — threshold ≥500 g/week for red meat. Mechanisms: N-nitroso compounds, heterocyclic amines, polycyclic aromatic hydrocarbons, heme iron. Prevention-persona RedFlag (§20 v0.3 lifestyle pilot).

Notes

Prevention-persona RedFlag for processed-meat consumption ≥50g/day. WCRF/AICR convincing evidence + IARC Group 1 classification for CRC. Effect size modest individually but population-attributable fraction non-trivial. Engine routes to PreventionPlan recommending dietary counseling + CRC screening per USPSTF. STUB pending two-Clinical-Co-Lead signoff per CHARTER §6.1 dev-mode.
