Introduction

Ultra-processed food was not an accident. Tobacco companies deliberately engineered processed food products to be addictive. They applied the same psychological research, flavour science, and design expertise they had spent decades using to hook smokers.

The findings come from one of the most comprehensive reviews of the food industry ever published. Eighteen research papers, along with more than 100 previously secret tobacco industry documents, form the basis. Published in the American Journal of Public Health in June 2026, the review depicts a commercial system built around reward, craving, and repeat consumption.

Big Tobacco Moved Into Your Kitchen

When Philip Morris bought General Foods and Kraft in the 1980s, it did not simply diversify. It brought cigarette science into the food supply.

Researchers from the University of California, San Francisco found that the company used cigarette design expertise, flavour engineering, and processing technologies to create Lunchables. This ready-made children’s meal brand launched in 1988. Product designers drew on psychological research to understand children’s unconscious desires. They built a product around a child’s drive for independence, autonomy, and play.

Professor Tara Fazzino from Kansas University examined the tobacco industry source documents. She found that US tobacco companies built multi-billion dollar global food businesses by leveraging their existing tobacco infrastructure. The playbook was not new. Only the product had changed.

Ultra-Processed Food and the Science of Addiction

Ashley Gearhardt, professor of psychology at the University of Michigan, surveyed more than 1,600 Americans. She set out to understand which ultra-processed food products triggered addiction and why.

The results were striking. Pepperoni pizza, chocolate chip cookies, French fries, glazed doughnuts, and potato chips scored highest for addictiveness. Whole foods did not register. As Gearhardt put it, no one reports feeling out of control around apple slices.

What set the addictive processed food products apart was their design. They deliver dense refined carbohydrates combined with fat at speed. This pairing does not occur in nature. But it appears constantly in the ultra-processed food aisle. Gearhardt called it a one-two punch. Over time, even the smell or packaging can trigger dopamine responses. Cravings begin before a person has eaten a single bite.

Clinical experience backs this up. Patients describe irresistible urges and an inability to stop. Even when they know the food is harming them. This is not a willpower failure. It is engineered response.

The Link Between Ultra-Processed Food and Dementia

Perhaps the most alarming findings concern cognitive decline. Research led by Harvard’s T.H. Chan School of Public Health followed more than 5,000 older Americans for nearly a decade. Those who ate the most ultra-processed food had a 58% higher risk of developing dementia. They also showed a 46% higher risk of mild cognitive impairment, and a 47% higher risk of either outcome.

Processed meats contributed most to dementia risk. These results held even after adjusting for income, education, smoking, physical activity, alcohol use, and baseline chronic disease. The associations are hard to explain away.

The findings add to existing evidence linking ultra-processed food consumption to obesity, cancer, type 2 diabetes, and cardiovascular disease.

Industry Tactics Mirror Tobacco Playbook

Lead author Nicholas Chartres from the Universities of Sydney and UCSF said the 18 papers together depict a commercial system. One that has engineered, marketed, and normalised products linked to widespread chronic disease.

The parallels to tobacco are not coincidental. They are structural. The same companies, the same scientists, and in many cases the same strategies were used to build both industries. Just as governments took decades to act on tobacco, researchers warn that meaningful policy on ultra-processed food remains frustratingly slow.

Professor Kelly Brownell, a global expert in food policy at Duke University’s Global Health Institute, argued that litigation may be the most effective way to break the deadlock. Legal action against tobacco companies forced policy change. Similar action against the food industry could do the same. Brownell and colleagues pointed to the potential for state Attorney General investigations in the US as a starting point.

Public Appetite for Action Is Growing

New polling included in the review found that roughly 70% of Americans believe ultra-processed food is addictive. Nearly three quarters support warning labels on harmful processed food products. Almost two thirds support advertising restrictions to protect children.

Across political lines, the majority support stronger government action. Proposed measures include health warning labels, taxes on ultra-processed food, and marketing restrictions targeting children. Litigation modelled on tobacco control is also on the table.

Taxes and penalties against large food companies could generate revenue to subsidise fruit and vegetables. That could make healthy food more affordable for lower-income households.

Shifting the Narrative From Personal Blame

One consistent theme in the review is the need to stop treating overconsumption of ultra-processed food as personal failure. Lindset Smith Taillie from the University of North Carolina at Chapel Hill welcomed the shift. The focus needs to move away from individual willpower. It should land squarely on the food industry that designs, manufactures, and markets these products, especially to children.

Marion Nestle, Emeritus Professor of Nutrition, Food Studies, and Public Health at New York University, acknowledged growing bipartisan support for action. She also cautioned that effective policy must remain grounded in evidence, not personal experience alone.

Alongside the publication, leading scientists and advocates launched a new movement called FedUP. It will translate research on ultra-processed food into accessible tools and resources for families, communities, and policymakers.

What This Means for Prevention

The evidence is now clear enough to act on. Ultra-processed food was engineered to override the body’s natural signals of fullness and satisfaction. The same industry that obscured the harms of tobacco applied those lessons to the food supply.

Understanding how processed food products are designed is not only a nutrition question. It is a public health and policy challenge. One that demands the same urgency, regulation, and community awareness that eventually transformed society’s response to tobacco.
