The modern food landscape is increasingly dominated by ultraprocessed foods – packaged snacks, sugary drinks, ready-to-eat meals, and fast food staples. But a growing body of research suggests these aren’t simply poor nutritional choices; they may be engineered to be addictive, triggering brain responses similar to those seen with substances like tobacco. This reframing of how we understand our relationship with food is prompting calls for a shift in public health strategies, moving beyond individual responsibility toward systemic change.
Researchers from the University of Michigan, Harvard University, and Duke University have published an analysis in The Milbank Quarterly exploring the striking parallels between ultraprocessed foods and tobacco products. The study draws on addiction science, nutrition research, and the history of tobacco regulation, arguing that both are deliberately formulated to maximize reward, encourage habitual consumption, and shape public perception to protect profits. Understanding these engineered qualities is crucial, particularly as rates of obesity and related health issues continue to rise.
How Food Can Become Habit-Forming
The core issue, according to Ashley Gearhardt, University of Michigan professor of clinical psychology and lead author of the study, is that certain foods are designed to be “hyperpalatable” – meaning they offer an unusually intense sensory experience. This combination of sugar, fat, and salt triggers reward pathways in the brain, releasing dopamine and creating a cycle of craving and consumption. “It may not be by accident that certain snacks perceive impossible to put down,” Gearhardt says. This isn’t simply about willpower; it’s about a biological response to intentionally engineered products.
This isn’t a new concept. The tobacco industry, for decades, deliberately manipulated nicotine levels and added ingredients to enhance addictiveness. They likewise employed sophisticated marketing strategies to normalize smoking and target vulnerable populations. The researchers argue that the food industry has adopted similar tactics, focusing on creating products that are not just tasty, but actively encourage overconsumption. A 2023 report by the World Health Organization (WHO) highlights the increasing prevalence of ultraprocessed foods in global diets and their associated health risks, including obesity, type 2 diabetes, and cardiovascular disease.

Shifting the Focus from Individual Choice to Systemic Factors
For years, public health messaging has largely focused on individual responsibility – encouraging people to develop better choices, exercise more, and practice self-control. Even as these messages aren’t without merit, the researchers contend that they overlook the powerful influence of the food environment. Young adults, in particular, are navigating a world saturated with cheap, readily available, and heavily marketed ultraprocessed foods.
The analysis suggests a need to examine the larger systems that shape food choices – the affordability, accessibility, and marketing of these products. Just as tobacco regulation evolved to hold companies accountable for the addictive properties of their products, the researchers propose a similar approach to food policy. This could include measures like taxes on sugary drinks, restrictions on marketing to children, and clearer labeling of ultraprocessed ingredients.
Implications for Public Health and Future Research
The researchers emphasize that the goal isn’t to equate eating with smoking. Rather, it’s to recognize that some foods are designed in ways that make moderation exceptionally difficult. This understanding has significant implications for how we approach public health interventions. Instead of solely focusing on individual behavior change, a more effective strategy may involve addressing the systemic factors that drive overconsumption of ultraprocessed foods.
The findings are intended to spark conversation, particularly among young adults who are shaping the future of food culture and health policy. If certain foods are intentionally engineered to be hard to resist, the conversation about health must move beyond blame and toward accountability. Further research is needed to fully understand the long-term effects of ultraprocessed food consumption and to develop effective strategies for mitigating their harmful impacts.
