Betcha can’t eat just one: Addiction to ultraprocessed foods is real and increasing
The Addictive Nature of Ultraprocessed Foods
Betcha can t eat just one – Why do some foods seem impossible to resist, as if they were calling out to us? It’s not just the richness of flavor or the comfort of familiarity, though those factors certainly play a role. Researchers now argue that the very design of ultraprocessed foods—those industrial creations packed with refined carbohydrates, added sugars, fats, and intense flavor enhancers—has evolved to trigger a biological response akin to substance dependency. Unlike Grandma’s classic chocolate chip-oatmeal cookies, which combine natural ingredients in a way that satisfies our primal cravings, modern ultraprocessed products are engineered to deliver a constant, escalating hit of pleasure. This has led to a growing concern that such foods may not only be tempting but also addictive, with nearly half of all American grocery store items falling into this category.
Clinical Criteria for Food Addiction
To qualify as “clinically” addicted, individuals must meet specific criteria outlined by the Yale Food Addiction Scale, which mirrors the diagnostic standards used for tobacco, drug, or alcohol use disorders. This framework assesses factors like loss of control over eating, persistent desire to consume, and withdrawal symptoms when deprived of the food. Dr. Ashley Gearhardt, a psychology professor at the University of Michigan, explains that this isn’t about willpower alone. “Grandma doesn’t have access to proprietary sensory scientists that create a burst of flavors that fade, leaving you wanting more,” she notes. These manufacturers use a combination of added sugars, refined carbs, salt, fats, and artificial flavorings to craft a “hedonic punch” that keeps people reaching for more, even when they’re full.
Neuroscience of Food Reward
Ultraprocessed foods are not just calorie-dense; they’re designed to hijack the brain’s reward system. According to Gearhardt, these products possess a “nutritional signature” that aligns with how our bodies evolved to seek out essential nutrients. For hunter-gatherer ancestors, sodium was vital for nerve function, carbohydrates provided energy, and fats were crucial for survival. Today, however, these nutrients are available in abundance, often in isolated, hyperpalatable forms. “Mother Nature never delivers these combinations in a single bite,” Gearhardt says. The result is a modern food environment where the body’s ancient drive for nourishment is manipulated to crave processed snacks over whole foods.
Modern Food Environment and Its Impact
Evan Forman, a professor at Thomas Jefferson University, highlights how the overabundance of ultraprocessed foods has shifted the balance of responsibility. “Instead of regulating our food, we’re pathologizing people, calling overeating a disease, and then prescribing them medication,” he argues. This perspective is supported by the rise in GLP-1 medications, which target obesity by suppressing appetite. Forman believes that the food industry’s strategies—such as creating addictive textures and flavors—are as deliberate as those used in pharmaceutical development. “Take heroin or fentanyl, for example,” he adds. “We don’t make the argument, ‘Well, you know, people should just resist heroin.’ It would not make sense to say everyone should rely on their willpower.”
Statistics on Food Addiction
The scale of the issue is becoming clearer. A recent study using the Yale Food Addiction Scale found that 14% of older adults in the U.S. and 21% of women aged 50 to 64 exhibit clinical signs of ultraprocessed food addiction. These figures are not static; they’re on the rise. Globally, 12% of children are now classified as addicted to UPFs, a statistic that underscores the urgency of addressing this problem. Gearhardt’s research has been instrumental in shaping policies like California’s new law, which aims to eliminate the most harmful ultraprocessed foods from school meals by 2035. Such measures reflect a growing recognition that addiction to these products is not a matter of personal choice but a systemic challenge.
The Study of Addictive Responses
To understand which UPFs are most addictive, Gearhardt and her team conducted a study involving 1,600 American adults. Participants were asked to evaluate the addictiveness of various foods, rating them on criteria like palatability, satiety, and the urge to consume more. The results were striking: over 90% of the most addictive foods were ultraprocessed items, including cookies, cakes, doughnuts, muffins, and sugary snacks. These products are engineered to provide a rapid dopamine boost, often surpassing the satisfaction derived from natural, nutrient-rich foods. “People come in with their favorite villain: ‘I think it’s fat.’ ‘I think it’s sodium.’ ‘I think it’s carbs,’ or whatever,” Gearhardt says. The study reveals that the combination of hyperpalatable ingredients—such as high levels of refined carbs and fats—creates an effect that is both powerful and persistent.
Industry and Government Inaction
Food scientists argue that the addiction crisis is fueled by a lack of oversight. “Americans are ‘fed up’ with industry and government inaction,” Gearhardt states. The accessibility of these foods, from vending machines to fast-food chains, makes it easier for people to overindulge. This is especially true in urban areas where processed meals are often cheaper and more convenient than whole foods. The pervasive presence of UPFs in daily life means that the body’s natural responses to hunger and satiety are constantly overridden. As a result, many individuals find themselves trapped in a cycle of craving, eating, and regret, even when they’re aware of the consequences.
The addictive potential of ultraprocessed foods is not just a matter of taste or convenience. It’s a complex interplay of biology, psychology, and industrial design. By understanding how these foods are constructed, we can better address the issue. For example, the relentless marketing of UPFs, coupled with their affordability and availability, has created a perfect storm for dependency. This has led to a broader debate about whether food addiction should be seen as a public health crisis or a personal failing. As the numbers continue to climb, it’s clear that the problem requires more than individual discipline—it demands systemic change.
Ultimately, the rise in ultraprocessed food addiction is a reflection of our modern dietary landscape. While our bodies are wired to seek out essential nutrients, the way these foods are engineered ensures that they are far more compelling. This has profound implications for health, from obesity to metabolic disorders. As Gearhardt and Forman emphasize, the solution lies in recognizing the science behind the cravings and taking steps to reform how these foods are produced, marketed, and consumed. Without such efforts, the cycle of addiction may only deepen, turning once-pleasurable treats into daily struggles for control.
“Food industry formulations are taking advantage—essentially exploiting a very deep-set and powerful biological response we have to certain substances,” Forman adds. “This isn’t just about indulgence; it’s about a system designed to keep us hooked.”
With the science and statistics now firmly in place, the conversation around ultraprocessed food addiction is gaining momentum. The question remains: How can we break free from the grip of these foods, and what does it take to make a meaningful difference in the way we eat? The answer may lie in a combination of education, policy reform, and a deeper understanding of the mechanisms that drive our cravings.
