Millions of people blame themselves when they cannot stop reaching for another biscuit or another handful of crisps. Research tells a different story. Ultraprocessed food addiction is now a clinically recognised condition. The evidence points not to personal failure but to deliberate product engineering.

Peer-reviewed research confirms that ultraprocessed food addiction meets the same diagnostic thresholds applied to tobacco, alcohol, and drug use disorder. Researchers use the Yale Food Addiction Scale, one of the most rigorous tools in addiction science.

The findings are sobering. 14% of older adults in the United States now meet the clinical criteria for ultraprocessed food addiction. Among women aged 50 to 64, that figure climbs to 21%. Globally, around 12% of children meet the same threshold.

Engineers of Craving

Ashley Gearhardt is professor of psychology at the University of Michigan and the researcher who developed the Yale Food Addiction Scale. She is direct about what drives addiction to ultraprocessed food. Food manufacturers, she explains, employ specialist sensory scientists. Their job is to craft a burst of flavours that fades quickly, leaving the consumer wanting more.

No single ingredient is responsible. The power lies in the combination. Refined carbohydrates, added sugars, fats, salt, flavourings and texturisers work together to generate an intense, reward-driven neurological response that whole foods cannot replicate.

“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.

These products target the brain’s ancient reward pathways. Those pathways evolved to push our ancestors toward scarce, calorie-rich foods. Food manufacturers have found a way to exploit them at industrial scale.

Biology as a Vulnerability

Human beings are wired, neurologically, to seek out sodium, carbohydrates and fat. For hunter-gatherer societies, obtaining enough of these nutrients was a daily matter of survival. That drive remains encoded in our biology.

The modern food environment turns it against us. Evan Forman is professor of family and community medicine at Thomas Jefferson University in Philadelphia. He describes how foods engineered to saturate ancient cravings are now instantly available through vending machines, fast-food outlets and online delivery.

“Food industry formulations are taking advantage, essentially exploiting a very deep-set and powerful biological response we have to certain substances,” Forman said.

He draws a direct comparison to illicit drugs. “Take heroin or fentanyl, for example. We don’t make the argument, ‘Well, people should just resist heroin.’ It would not make sense to say everyone should rely on their willpower.”

Addictive ultraprocessed foods deserve the same honest framing. Placing the burden on individual consumers while shielding industry practices from scrutiny is neither scientifically accurate nor ethically sound.

Which Products Carry the Greatest Risk

Not every ultraprocessed product carries equal addiction risk. Gearhardt surveyed 1,600 American adults to identify which food characteristics were most strongly linked to compulsive consumption. One combination dominated the findings.

More than 90% of products in the highest addiction-risk tier delivered both high refined carbohydrates and high fat, packaged in calorie-dense forms. The foods named most often: packaged biscuits, cakes, doughnuts, crisps, pizza, fast-food chicken, breakfast sandwiches, and processed pasta dishes.

Critically, rapidly digestible starches, not just added sugar, drive much of the risk. This is key to understanding addictive ultraprocessed foods.

“Our findings suggest that focusing exclusively on sugar may miss part of the picture,” Gearhardt said. “Many potato crisps contain little or no added sugar, yet they still deliver rapidly absorbed carbohydrates.”

That rapid glucose spike is followed by a sharp drop in blood sugar. The result is a hollow, unsatisfied feeling that pushes people toward the next serving. Often, this happens before they have fully registered what they already consumed.

The Health Costs

The consequences of ultraprocessed food addiction reach well beyond compulsive eating. Research links higher consumption of these products to a range of serious health outcomes.

Eating just 10% more ultraprocessed food per day is associated with:

• A 55% higher risk of obesity
• A 50% rise in cardiovascular disease-related death
• A 40% increased risk of type 2 diabetes

A 2024 study found that a 10% rise in ultraprocessed food consumption may also increase risk of cognitive decline and stroke. Research published in 2023 linked higher intake to greater risk of certain upper digestive tract cancers. A 10% increase amounts to just one extra serving per day.

Clinical trials conducted in closely monitored hospital settings showed striking results. People on an ultraprocessed diet consumed 500 to 1,000 additional calories each day. Those calories were above and beyond what people eating minimally processed whole foods consumed. No instruction to eat more was given.

Industry Pushback

The International Food and Beverage Alliance represents major food manufacturers. It rejects the framing of ultraprocessed food addiction as a clinical problem. “Enjoyment and palatability are normal parts of eating. They are not unique to foods labelled ultra-processed, nor are they evidence of clinical addiction,” said IFBA Secretary General Rocco Renaldi.

The alliance also argues that many ultraprocessed products contribute important nutrients and appear in dietary guidelines around the world.

Researchers counter this firmly. The clinical criteria for ultraprocessed food addiction are as stringent as those for any other recognised substance use disorder. Meeting those criteria requires demonstrable loss of control, continued use despite harm, and repeated failed attempts to stop. That is not a question of preference or perception.

Warning Signs

Tera Fazzino is associate professor of psychology at the University of Kansas. She describes how addictive ultraprocessed foods recalibrate taste expectations over time. “Hyperpalatable foods exaggerate the eating experience. Because they are everywhere, they are changing our taste buds to expect those levels of sugar, salt and fat,” she said.

Gearhardt emphasises that not everyone who eats these products will develop clinically significant problems. Not every person who drinks alcohol develops alcohol use disorder. Genetics, stress, mental health and the extent of exposure to engineered food marketing all shape individual risk.

She cautions, however, against framing ultraprocessed food addiction as all-or-nothing. Many people sit somewhere on a spectrum of addictive pull toward these products, even without meeting the full clinical threshold.

Signs that a problem may be developing include:

• Eating past the point of fullness on a regular basis
• Eating particular foods in response to cravings rather than hunger
• Hiding certain foods or eating them alone
• Failed attempts to cut back despite fatigue, mood swings or weight gain
• A specific food generating intense, intrusive cravings or occupying significant mental space

“If a particular food starts taking up a lot of mental space, triggers intense cravings, or repeatedly derails intentions, those may be important warning signs,” Gearhardt said.

The Case for Upstream Action

California has already acted. A law informed by Gearhardt’s research will remove the most harmful ultraprocessed products from billions of school meals by 2035. Responsibility is placed at the level of product design and market regulation, not individual behaviour.

Forman points to the rapid rise of GLP-1 weight-loss medications as evidence of what happens when the food environment goes unaddressed. “Instead of regulating our food, we’re pathologising people, calling overeating a disease, and then prescribing them medication,” he said.

Ultraprocessed food addiction is not a story about weak individuals in a neutral environment. It is a story about an industry that has engineered products to override the human capacity to stop. It is also a story about a regulatory landscape that has not yet caught up with the consequences.
