From Tobacco to Ultraprocessed Food: How Industry Engineering Fuels the Epidemic of Preventable Disease

This review synthesizes findings from addiction science, nutrition, and public health history to identify structural and sensory features that increase the reinforcing potential of both cigarettes and UPFs. We focus on five key areas: dose optimization, delivery speed, hedonic engineering, environmental ubiquity, and deceptive reformulation.

Cigarettes and UPFs are not simply natural products but highly engineered delivery systems designed specifically to maximize biological and psychological reinforcement and habitual overuse. Both industries have used similar strategies to increase product appeal, evade regulation, and shape public perception, including adding sensory additives, accelerating reward delivery, expanding contextual access, and deploying health-washing claims. These design features collectively hijack human biology, undermine individual agency, and contribute heavily to disease and health care costs.
