Recent studies reveal a concerning connection between ultraprocessed foods and addictive behaviors typically associated with tobacco. As consumption of these foods increases, understanding their impact on our health and behavior becomes more vital.
- A recent review found that ultraprocessed foods (UPFs) may be as addictive as tobacco products.
- The researchers found that UPFs are designed to heighten reward and accelerate the delivery of reinforcing ingredients.
- The “addictive” quality of these foods means they drive compulsive consumption and disrupt appetite regulation.
- The review authors suggest that ultraprocessed foods should be subject to regulations similar to those for tobacco products.
At present, there is no universally accepted definition of ultraprocessed foods. Some define them as items that include ingredients you would not typically find in a home kitchen, like emulsifiers and various additives.
Many experts utilize the NOVA classification, which describes ultraprocessed foods as formulations predominantly made from industrially manufactured ingredients, often created through multiple industrial techniques and processes.
Dr. Mir Ali, a bariatric surgeon and medical director at MemorialCare Surgical Weight Loss Center in Fountain Valley, CA, stated, “I agree with this study, as ultra-processed foods are specifically engineered to be highly appealing to most individuals,” underscoring the engineering behind these products.
According to the research team from Harvard, Duke, and the University of Michigan, “Cigarettes and UPFs are not simply natural products but highly engineered delivery systems designed specifically to maximize biological and psychological reinforcement and habitual overuse.”
The review aimed to synthesize findings from addiction studies, public health history, and nutrition to identify sensory and structural elements that enhance the reinforcing potential of both cigarettes and ultraprocessed foods.
Michelle Routhenstein, a preventive cardiology dietitian at EntirelyNourished, emphasized, “Not everyone is ‘addicted’ to these foods, but for a significant minority, they trigger classic addiction-like patterns: strong cravings, loss of control, and continued use despite negative health effects.”
She added, “These foods are deliberately engineered with refined carbohydrates, added fats, salt, and flavor enhancers to maximize reward and encourage repeated consumption, with particularly aggressive marketing strategies targeting children.”
The researchers examined five critical areas:
- delivery speed
- hedonic engineering, or designing foods to be irresistibly good
- dose optimization
- environmental ubiquity
- deceptive reformulation, or “health washing”
They discovered that, similar to cigarettes, ultraprocessed foods are meticulously calibrated to deliver an optimal dose of sugar.
“Refined carbohydrates stimulate dopamine release through the vagus nerve, while fats do so through intestinal lipid sensing,” the study explains.
“Ultraprocessed foods with high levels of refined carbohydrates and added fats are among the most rewarding substances in today’s diet. This refined carbohydrate-fat combination is largely absent in nature.”
The rapid delivery of enjoyable chemicals to the brain raises the potential for addiction in these foods, much like nicotine in cigarettes.
While cigarettes are engineered for quick nicotine delivery, ultraprocessed foods are crafted for rapid digestion and absorption. Their low fiber content facilitates quicker processing of fats and sugars.
Moreover, ultraprocessed foods provide immediate flavor bursts that quickly diminish, along with textures that melt in the mouth, further enhancing dopamine release and encouraging increased consumption.
The review noted that both the tobacco and food industries have historically employed a strategy known as “health washing.”
This approach involves marketing and reformulating products to create the perception of reduced harm while maintaining their addictive qualities.
In the tobacco sector, health washing became prominent in the 1950s with the introduction of filtered cigarettes, marketed as protective innovations designed to trap harmful tar and particles. In reality, filters provided minimal benefits, leading users to inhale deeper or smoke more frequently, negating any potential reductions in toxin exposure.
The food industry has adopted similar practices, using labels like “low fat” or “sugar-free” to promote ultraprocessed products.
Despite these claims, the same highly reinforcing ingredient combinations remain, offering a mere illusion of health while the underlying addictive structure persists.
In concluding their research, the authors emphasized that while food and tobacco are inherently different, there are concerns regarding certain ultraprocessed foods that function more as optimized products than as genuine food.
They argued for public health policies that acknowledge this phenomenon. “Tobacco serves as a cautionary tale, while tobacco control provides a beacon of hope,” they noted.
Thanks to regulations, smoking rates in the U.S. have significantly dropped, reshaping public perception of tobacco and diminishing trust in the industry.
Dr. Ali emphasized, “Increased education about the negative impacts of ultra-processed foods is crucial to curbing consumption and enhancing public health. Strategies employed to reduce cigarette usage may also serve as an effective framework for addressing ultraprocessed foods.”
Routhenstein urged, “While ultraprocessed foods shouldn’t be regulated exactly like cigarettes, they do merit stronger, tobacco-inspired policies: marketing restrictions, clear front-of-package labeling, stricter standards on health claims, and limitations in schools or hospitals.”
The researchers reiterated that minimally processed and unprocessed foods have supported human health for centuries.
“Legal actions regarding health damages, restrictions on UPF marketing, taxation on nutrient-poor UPFs, reducing UPFs in schools and hospitals, and clearer labeling regarding ultraprocessing are all viable next steps,” they stated.
“Policies treating UPFs with the same seriousness once reserved for tobacco, while actively promoting real food, represent the most promising route out of the current health crisis.”
Routhenstein concurred, advocating for public policy measures that improve access to fresh, minimally processed foods, especially in underprivileged neighborhoods. This could be achieved through subsidies, support for local markets and grocery stores, and programs within schools or workplaces.
“Making real food affordable and convenient will reduce dependence on UPFs and address systemic issues that perpetuate unhealthy eating patterns,” Routhenstein concluded.
