RFK Jr, MAHA, and the fight for America’s diet - What’s really going on | Dr Jessica Knurick
The Proof with Simon Hill
About
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.
You can connect with Dr Jessica Knurick on Instagram and TikTok, or visit her website and Substack to explore her work and evidence based insights on public health, nutrition and the systems shaping our wellbeing.
