Episode notes
Correlation vs. Causation
- Correlational studies only reveal coincidences, not causal relationships.
- The World Health Organization's claim that red meat is "probably carcinogenic" is based on correlational evidence.
Relative vs. Absolute Risk
- Studies on red meat and cancer often present data as relative risk, not absolute risk.
- A 50% increased risk from 1% is only 1.5%, not 50%.
Focus on Total Mortality
- Consider total mortality, not just mortality from specific diseases like cancer when evaluating dietary studies.
- A longer lifespan matters more than cause of death.
