Improving Scientific Literacy: Correlation vs Causation

Dr Jessica Knurick joins me to examine the systems influencing America’s health. We discuss the gap between individual choices and public health realities, the rise of MAHA, and why many proposed solutions fail to address the real drivers of chronic disease.

Jessica breaks down regulation, subsidies and the role of corporations, the truth about food dyes and additives, and why SNAP remains essential for reducing food insecurity and improving health outcomes.

What We Cover

• Jessica’s path into public health communication
• Individual behaviour versus systemic influence
• The MAHA movement and its limitations
• How regulation and subsidies shape our food environment
• What the evidence really shows about additives and food dyes
• Why SNAP matters and the consequences of defunding
• Policies that could genuinely improve child and adult health

A timely and important conversation that brings clarity to a confusing and polarised nutrition landscape.
