Ultra-Processed People
Chris van Tulleken · 2023
Ultra-Processed People (2023) is a book by Chris van Tulleken on health & the body. Physician Chris van Tulleken argues ultra-processed food is a distinct, addictive category, defined by industrial processing, not nutrients, engineered to be overconsumed, and driving obesity and disease worldwide.
A doctor eats 80% ultra-processed food for a month, watches his own brain and body change, and proves the problem isn't your willpower, it's a category of food engineered to be overeaten.
Two of the ideas you’ll keep
The Clif summary of Ultra-Processed People pulls out 7 insights. Here are the first two.
- Ultra-processed food (**UPF**) is defined by the **NOVA classification**, not by fat, salt, or sugar: NOVA Group 4 is food made largely from industrial substances and additives you'd never find in a home kitchen, which makes it a distinct category rather than just 'unhealthy food.'
- Van Tulleken's practical test: if it's **wrapped in plastic and contains at least one ingredient you wouldn't find in a standard domestic kitchen**, emulsifiers, modified starch, protein isolates, flavourings, it's almost certainly UPF, even if the label screams 'natural' or 'high protein.'
