Canon

Van Tulleken: UPF is industrially formulated to maximize consumption. The combination of refined carbs, seed oils, emulsifiers, and flavorings bypasses normal satiety signaling, causing overconsumption independent of willpower.

Highlights

The NOVA classification system — not all processed food is equal
Van Tulleken: the NOVA system classifies food into four groups based on degree of processing. Group 4 (ultra-processed) includes ingredients you wouldn't find in a home kitchen — emulsifiers, flavor enhancers, colorants — and these are the foods driving the obesity epidemic.
