Research indicates that tobacco companies have played a significant role in the creation and promotion of ultra-processed foods (UPFs), applying their expertise in flavor, marketing, and product design to develop addictive food items. This insight comes from a comprehensive review published in the American Journal of Public Health on Wednesday, which reveals the connections between UPFs and rising health issues such as obesity, cancer, dementia, and diabetes.

The study defines UPFs as items that cannot be easily made at home due to their inclusion of additives like colors, flavors, and emulsifiers. Lead author Nicholas Chartres, associated with the Universities of Sydney and California, San Francisco, noted that the commercial system has effectively engineered and normalized products linked to chronic diseases.
Evidence from over 100 previously confidential documents from the tobacco industry was examined by Professor Tara Fazzino of Kansas University. She found that American tobacco companies had established multi-billion dollar food enterprises by utilizing their infrastructure from tobacco. Laura Schmidt from UCSF highlighted Philip Morris's development of Lunchables, a ready-made food for children, which launched in 1988 following the company’s acquisition of General Foods and Kraft.
Schmidt explained that the design of Lunchables was rooted in psychological research aimed at appealing to children's desire for independence and play.
In a separate study, Ashley Gearhardt, a psychology professor at the University of Michigan, assessed food addiction among a diverse sample of over 1,600 Americans. Participants identified foods such as pepperoni pizza, chocolate chip cookies, and French fries as highly addictive, with the carbohydrate-fat combination in UPFs contributing significantly to these cravings.
Research on the health effects of UPFs has raised alarming concerns, especially related to dementia. A study led by Dr. Heejin Lee at Harvard's TH Chan School of Public Health found that older Americans consuming the most UPFs faced a 58% higher risk of developing dementia, a 46% higher risk of mild cognitive impairment, and a 47% higher risk of similar outcomes.
Melanie Nestle, a nutrition professor at NYU, noted bipartisan support in the U.S. for measures to reduce the impact of UPFs, indicating that movements like Make America Healthy Again (MAHA) have brought attention to these harmful products. However, she criticized the movement's approach as being based on feelings rather than science.
International examples, such as Chile's mandatory labeling on UPFs, demonstrate potential avenues for improving consumer choices. Polling data indicates that roughly 70% of Americans believe UPFs are addictive, and many support health warning labels and marketing restrictions targeted at children.
The authors advocate for stronger consumer protection laws for UPFs, calling for health warning labels and advertising restrictions similar to those in tobacco control. They emphasize that litigation against harmful practices of big food corporations might catalyze healthier policies. Kelly Brownell, a food policy expert at Duke University, remarked on the lengthy process of policy implementation in the face of known health risks.
In conjunction with the research's publication, a new consumer education initiative called FedUP! has been launched, aimed at disseminating evidence-based information about the impacts of UPFs on health to empower families and communities.
