Topic: Healthy User Bias

Nutritional science often relies on observational studies that are prone to "healthy user bias," where people who eat less meat also tend to smoke less and exercise more. Dr. Leroy argues that these weak associations are often presented as causal relationships to support anti-meat agendas. He notes that in non-Western contexts, higher meat consumption is frequently associated with better health, suggesting that the current scientific paradigm cherry-picks data to advance specific policy goals.
