Ultra Processed People: Why Do We All Eat Stuff That Isn’t Food… and Why Can’t We Stop? is a gripping examination of how ultra‑processed foods (UPFs) are reshaping our bodies, brains, and societies. Dr. Chris van Tulleken, a British infectious‑disease physician trained at Oxford with a PhD in molecular virology from University College London, leverages his scientific expertise and BBC‑broadcasting experience to guide readers through a compelling mix of personal experiment, historical research, and investigative journalism.

Van Tulleken in Ultra Processed People begins by defining UPFs using the NOVA system—industrial formulations packed with additives, flavorings, and novel molecules that are foreign to our physiology. To illustrate their effects, he undertakes a bold self‑experiment: one month consuming mostly whole foods, followed by a month deriving 80 % of calories from UPFs. His findings are startling. He gains weight, suffers inflammation, mood swings, and physical aging, while his family shows similar adverse effects.

He traces UPFs back to the late 19th century—beginning with saccharin’s invention in 1879 and continuing through the proliferation of additives like emulsifiers and sweeteners designed for profit, shelf‑life, and hyper‑palatability. He highlights how manufacturers design foods to hijack reward systems in the brain, leading to compulsive overeating and undermining satiety.

Van Tulleken also dissects the food industry’s stealth influence on science, policy, and public perception—evoking parallels to tobacco lobbying—and emphasizes the importance of recognizing conflicts of interest in nutrition research.

He concludes with pragmatic guidance: read labels, reduce UPF intake, and choose real food found in a kitchen. Throughout, his dual identity as physician and broadcaster ensures the narrative is rigorous yet engaging. Raised to public attention through shows like Operation Ouch! and Trust Me, I’m a Doctor, van Tulleken uniquely bridges medical authority and accessible storytelling.
