“Hyperpalatable” foods combine sugar, fat, and salt in proportions that are rare in whole foods and ubiquitous in processed ones — combinations that overstimulate reward pathways and suppress satiety signals. Fazzino and colleagues identified three key combinations that trigger excessive consumption. They show reward-region activation resembling substance dependence — a blood-oxygen signal rather than dopamine — though how closely that parallel runs in people is still unsettled. The “can’t stop” experience isn’t weakness — it’s the intended response to products designed for that effect.
This companion explores the hyperpalatability formula, the reward system hijack, why satiety fails, and practical implications for recognition and avoidance. (5 min read)
Known defects on this page:
- em dashes were set without spaces The site's style spaces its dashes; 351 pages carried them un-spaced, and every one was corrected.
- Our library's voice leaked into the prose. The underlying honesty was correct; the sentences are being rewritten to speak about the evidence rather than about our files.
- We overuse the em dash in our prose. We use the em dash more often than easy reading allows, and we are changing how we punctuate.
