Evidentiary-status ledger for 25 claims, from PUFA oxidation to regulatory capture

Filter rows

Claim / Topic	Assigned Evidentiary Status	Analytical & Practical Application
PUFA Oxidation Chemistry	Established Mechanism	Polyunsaturated fats oxidize under heat, light, and oxygen to form 4-HNE/MDA. Saturated fats are chemically more stable.
LDL-C vs. Particle Quality	Resolved by Synthesis	LDL-C measures circulating cholesterol mass; particle size/oxidation determines arterial penetration and foam cell plaque formation.
Foam Cell Formation	Established Mechanism	Macrophages ingest small, dense, oxidized LDL particles within arterial walls, becoming foam cells that build plaque core.
"Cholesterol Is Irrelevant"	Weak / Not Supported	Unsupported claim. Total LDL-C provides necessary raw material; it is incomplete as a standalone metric, not irrelevant.
Mortality-Trend Arguments	Weak / Not Supported	Isolated trend arguments (for/against statins or seed oils) are heavily confounded by smoking, acute care, and blood pressure control.
Crisco / Cottonseed History	Documented Fact	Cottonseed oil shifted from industrial waste to human food via P&G hydrogenation in 1911.
Keys 1953 vs. 1957 Critique	Documented Fact	Keys' 6-country graph (1953) was critiqued by Yerushalmy & Hilleboe (1957) using 22 countries. Distinct from Seven Countries Study.
Seven Countries Study	Documented Fact / Criticism	Prospective study using non-random country selection; observed sugar and fat correlations but emphasized fat.
French Paradox Raw Data	Documented Fact	1992 CHD mortality was 128/100k in France vs. 345/100k in US (2.7:1 ratio) despite higher French fat intake.
French Under-Reporting	Documented Fact / Confound	Up to 20% under-reporting in France. Corrected rate (128÷0.80=160) leaves US rate at 2.16 times France (gap narrows ~15%).
Law & Wald Time-Lag	Contested Explanation	Proposed that French heart disease lags behind fat intake increases by decades. Rejects red wine as a primary explanation.
Pre-1920 US Mortality Gap	Documented Fact / Confound	Herrick described MI in 1912; ECG arrived in 1920s. Pre-1920 cardiac deaths were recorded as apoplexy/dropsy.
Century of Intervention	Documented Fact / Confound	Modern rates (~200–240) match 1900 baseline (265.4); comparison is confounded by pre-1920 under-reporting and rising life expectancy.
US Diabetes & Pediatric Trends	Documented Fact	US adult diabetes reached ~14.3% (total); pediatric chronic conditions rose above 30% by 2018 (CDC/NHANES).
GRAS Exemption Pathway	Documented Fact	Legal pathway allowing manufacturers to self-affirm additive safety without mandatory FDA notification.
FDA User-Fee Funding	Documented Fact	PDUFA legislation established industry user fees to fund agency drug review operations.
Glyphosate Carcinogenicity	Documented Fact	Disputed split: IARC classified as Group 2A (probable carcinogen); EPA/EFSA classified as unlikely to pose human cancer risk.
Shikimate Pathway	Established Mechanism	Inhibits amino acid synthesis in plants and gut bacteria. Lacking in human cells; dietary microbiome impact remains under active study.
Glyphosate-Celiac Correlation	Correlation, Confounded	Samsel & Seneff correlation fails to prove causation and ignores the surge in diagnostic serology testing during the 1980s–1990s.
Antibiotics & Microbiome	Established Mechanism	Antibiotic overuse depletes gut microbiome diversity. Direct causal link to population cancer rates remains unproven.
Schopenhauer Epigraph	Sourced Quote	Counsels and Maxims (1851). Advises evaluating facts dispassionately like a mineralogist studying a specimen.
Regulatory Capture	Documented Fact	Established economic model (Stigler) describing corporate capture of regulatory agencies.
Scientific Method Tension	Epistemological Point	Invoking "trust the science" to foreclose inquiry conflicts with the scientific method's requirement for continuous falsifiability.
Political Label Shifts	Documented Fact	Historical realignment of political platforms shows ideological labels are unstable proxies for scientific truth.
AI Gatekeeping Concerns	Stated Perspective	Host's perspective: Warns against automated enforcement of institutional consensus that suppresses valid minority scientific research.
