Professor Hannah Fry has warned that Pringles are deliberately engineered to prevent people from feeling full, leading to overconsumption. Speaking on the Table Manners podcast, the University of Cambridge mathematician explained that the ultra-processed snack dissolves before reaching the part of the intestine that releases fullness hormones.
Fry said: 'They are so processed, they're basically pre-digested. So once you pop, you can't stop, quite literally. You will never get full on them.' She added that food companies optimise for volume consumed rather than taste during testing, effectively 'hacking our bodies against us'.
Food scientist Tim Spector, who previously admitted to being addicted to Pringles, noted that the combination of fat, sugar, salt, and a melt-in-the-mouth texture makes them 'hyper-palatable' and easy to overeat. He said the rapidly dissolving texture allows the snack to enter the bloodstream quickly, bypassing natural fullness signals.
BBC Good Food has listed Pringles among the most harmful ultra-processed foods, citing ingredients such as dehydrated potato, refined oils, emulsifiers, and flavourings. The high-temperature frying process may also produce acrylamide, a potential carcinogen, though human studies remain inconclusive.
