Every factual claim on Coffee Studies is cited against this registry of studies, agency guidance, and official datasets. Sources are graded by evidence strength: Tier 1 — umbrella and systematic reviews, regulatory guidance, official statistics. Tier 2 — individual studies, narrative reviews, institutional overviews. Tier 3 — encyclopaedias and industry references used for context, not health claims.
