A recent report suggests that ultra-processed foods (UPFs) should be regulated more strictly, akin to cigarettes, due to their potential for addiction and associated health risks. Researchers from Harvard, the University of Michigan, and Duke University published their findings on February 3 in the Milbank Quarterly, highlighting the similarities between UPFs and tobacco products in terms of engineering and health impacts.

UPFs, which are widely available, include items like soft drinks and packaged snacks, and are characterized by industrial manufacturing processes that often involve emulsifiers, artificial colors, and flavors. The study asserts that both UPFs and cigarettes are designed to optimize consumption by acting on the brain's reward pathways, leading to addiction.
The authors criticize marketing tactics that suggest UPFs are healthier, comparing them to misleading advertising for cigarette filters in the 1950s. These tactics can hinder necessary regulations, creating a false sense of safety around products labeled as “low fat” or “sugar-free.”
Ultra-processed foods contain high levels of salt, sugar, and fat, which are linked to obesity, cancer, type 2 diabetes, and cardiovascular disease. They also tend to lack essential nutrients like protein, zinc, and vitamins that are crucial for child development. Additionally, the study indicates that UPFs might negatively impact gut microbiota, further complicating health outcomes.
Professor Ashley Gearhardt of the University of Michigan noted that her patients often draw parallels between their cravings for UPFs and their past experiences with smoking, expressing a struggle to quit despite knowing the negative health implications. She argues that the focus on individual responsibility has overshadowed the role of the industry in creating addictive products.
While food is essential for survival, the researchers assert that this reality makes regulation of UPFs even more critical. They propose that, similar to alcoholic beverages, harmful UPFs could be distinguished from healthier options.
The paper also discusses the need for adopting regulatory practices from tobacco control, such as litigation and marketing restrictions, emphasizing a shift towards holding the food industry accountable. Professor Martin Warren from the Quadram Institute cautioned against overreaching in comparisons between UPFs and tobacco, suggesting that the addiction potential of UPFs may not be pharmacological but rather linked to learned behaviors and convenience.
Dr. Githinji Gitahi, CEO of Amref Health Africa, expressed concern over the impact of weak regulations on UPFs across Africa, calling attention to the increasing health burdens on already strained health systems without adequate public health interventions.
