Betcha can’t eat just one: Addiction to ultraprocessed foods is real and increasing

The Science Behind the Cravings

Betcha can t eat just one – Can food be addictive? The question has sparked debate among scientists, with evidence suggesting that ultraprocessed foods—those heavily modified, nutrient-dense products that dominate grocery store shelves—may trigger cravings as potent as those for nicotine or alcohol. While the idea of food addiction might seem unusual, researchers are increasingly pointing to the unique combination of ingredients in these foods as a key factor. Studies indicate that an estimated 70% of items in typical stores are ultraprocessed, and their ability to activate the brain’s reward systems is being scrutinized as a potential cause of compulsive eating behaviors.

“Grandma doesn’t have access to proprietary sensory scientists that create a burst of flavors that fade, leaving you wanting more,” said Ashley Gearhardt, a professor of psychology at the University of Michigan in Ann Arbor. Gearhardt, who developed the Yale Food Addiction Scale, emphasized that modern food manufacturers use precise blends of sugar, salt, fat, and flavor enhancers to craft products that are hyperpalatable and designed to encourage repeated consumption.

The scale, which evaluates addiction through criteria similar to those for substance use disorders, has revealed alarming trends. According to the latest data, 14% of older adults and 21% of women aged 50 to 64 in the U.S. now meet the threshold for clinical food addiction. These figures are rising, suggesting that the problem is not just a matter of personal choice but a systemic issue tied to the food industry’s strategies.

A Modern Food Environment

Ultraprocessed foods are engineered to maximize pleasure and minimize satiety, exploiting the primal biological drives that once ensured survival. While humans evolved to seek out calories from natural sources like whole grains, fruits, and lean proteins, today’s foods deliver these nutrients in concentrated, easily accessible forms. “Foods packed with these key nutrients are easily and instantaneously available in every vending machine, fast-food restaurant, and grocery store—and can even be purchased online and delivered to your door,” explained Evan Forman, the Ellen M. & Dale W. Garber Professor of Family & Community Medicine at Thomas Jefferson University in Philadelphia.

“If you look at the phenomenon of GLP-1 medications, this overabundance is what they are treating,” Forman said. “Instead of regulating our food, we’re pathologizing people, calling overeating a disease, and then prescribing them medication.” His argument highlights a growing concern: the modern food system is not just changing dietary habits but reshaping how we perceive and experience hunger.

Forman’s research underscores the role of food industry formulations in driving addictive behaviors. “Take heroin or fentanyl, for example,” he added. “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.” This analogy underscores the idea that ultraprocessed foods are not merely tempting but engineered to override self-control mechanisms.

From Survival to Compulsion

Our ancestors relied on calorie-dense foods to survive, with sodium, glucose, and fats playing critical roles in energy storage and bodily functions. However, the nutrients essential for life are now delivered in ways that bypass natural satiety signals. “The human brain is nearly 60% fat, so storing fat about the body was a priority for our hunter-gatherer ancestors,” Gearhardt noted. Today, this evolutionary drive is hijacked by products that combine high levels of refined carbohydrates, added sugars, and fats into a single bite.

“Ultraprocessed products have a nutritional signature—based on the neuroscience of food reward—that Mother Nature never delivers to you in a single food,” Gearhardt said. This signature is not accidental; it’s the result of deliberate scientific manipulation. Flavorings, texturizers, and other additives are used to create an intense, pleasurable, and addictive combination that keeps consumers reaching for more.

Research reveals that the most addictive foods are often those found in supermarkets, including cookies, cakes, doughnuts, and candies. A study involving 1,600 American adults identified that over 90% of the most addictive products in the highest perceived addictiveness tier were ultraprocessed, with refined carbs and fats as their primary components. “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 observed. The study aimed to pinpoint the specific ingredients responsible for the strongest cravings.

Global Trends and Policy Responses

On a global scale, the issue is equally pressing. Gearhardt reported that 12% of children are now classified as clinically addicted to ultraprocessed foods, a statistic that has informed policy changes. California, for instance, recently passed a law requiring the removal of the most harmful ultraprocessed foods from school meals by 2035. This move reflects a growing recognition of the role these foods play in shaping unhealthy eating patterns from an early age.

Despite these efforts, the food industry remains a central player in the addiction crisis. “Ultraprocessed food scientists say Americans are ‘fed up’ with industry and government inaction,” Gearhardt remarked. The challenge lies in balancing the convenience and appeal of these foods with their impact on health. While not all ultraprocessed items are equally addictive, the combination of ingredients in many products creates a powerful lure that’s difficult to resist.

Toward a Deeper Understanding

Understanding the addictive nature of ultraprocessed foods requires looking beyond individual choices. It involves examining how these foods are designed to interact with the brain’s reward pathways, encouraging overconsumption and dependency. As the percentage of clinically addicted individuals grows, so does the need for comprehensive approaches to address the issue. This includes not only individual behavior modification but also regulatory changes and public awareness campaigns.

“Food industry formulations are taking advantage—essentially exploiting a very deep-set and powerful biological response we have to certain substances,” Forman said. The scale of the problem is significant, with millions of people facing a daily battle against foods that are both delicious and damaging. The rise of GLP-1 medications and the increasing focus on food addiction as a medical condition highlight the urgency of this issue.

As the evidence mounts, the conversation around food addiction is evolving. What was once seen as a matter of personal willpower is now recognized as a complex interplay of biology, environment, and industry influence. The question remains: how can we reconcile the convenience of ultraprocessed foods with their growing role in compulsive eating behaviors? The answer may lie in a combination of policy reforms, education, and a deeper understanding of how these foods manipulate our instincts to satisfy cravings in ways that defy nature’s original design.

With 14% of older adults and 21% of women in their 50s to 60s already meeting the criteria for clinical addiction, the trend is clear. The challenge is to redefine how we approach food, moving away from blaming individuals and toward addressing the systemic factors that make ultraprocessed foods so irresistible. As the world grapples with this issue, the hope is that awareness and innovation will lead to healthier choices and a future where “betcha can’t eat just one” is no longer a guaranteed outcome.
