Can extremely processed meals be addictive?
It’s a query that researchers have debated for years as unhealthy diets are sometimes fueled by meals loaded with refined carbohydrates and added fat.
To discover a decision, a brand new College of Michigan and Virginia Tech evaluation took the factors utilized in a 1988 U.S. Surgeon Common’s report that established that tobacco was addictive and utilized it to meals.
Primarily based on the factors set for tobacco, the findings point out that extremely processed meals could be addictive, mentioned lead creator Ashley Gearhardt, U-M affiliate professor of psychology, and Alexandra DiFeliceantonio, assistant professor at Fralin Biomedical Analysis Institute at Virginia Tech.
The truth is, the addictive potential for meals equivalent to potato chips, cookies, ice cream and French fries could also be a key issue contributing to the excessive public well being prices related to a meals atmosphere dominated by low-cost, accessible and closely marketed extremely processed meals, the researchers mentioned.
The analysis, revealed within the present situation of Dependancy, provides proof that extremely processed meals meet the identical standards used to determine cigarettes as an addictive substance:
- They set off compulsive use the place persons are unable to give up or lower down (even within the face of life-threatening ailments like diabetes and coronary heart illness)
- They will change the best way we really feel and trigger modifications within the mind which are of an identical magnitude because the nicotine in tobacco merchandise
- They’re extremely reinforcing
- They set off intense urges and cravings
“Of word, there is no such thing as a biomarker within the mind that tells us whether or not one thing is addictive or not,” Gearhardt mentioned. “Figuring out that tobacco merchandise have been addictive actually boiled down to those 4 standards, (which) have stood as much as many years of scientific analysis. Extremely processed meals meet each single one in all these standards.”
DiFeliceantonio mentioned the flexibility of extremely processed meals to quickly ship unnaturally excessive doses of refined carbohydrates and fats seem key to their addictive potential.
Extremely processed meals comprise complicated substances that can’t be simplified to a single chemical agent performing by means of a particular central mechanism. The identical could be mentioned for industrial tobacco merchandise, which comprise hundreds of chemical compounds together with nicotine, Gearhardt mentioned.
When the Surgeon Common’s report was launched greater than 30 years in the past, tobacco merchandise have been the biggest explanation for preventable dying. However many individuals and tobacco producers resisted accepting their addictive and dangerous nature.
“This delayed the implementation of efficient methods to deal with this public well being disaster, which price thousands and thousands of lives,” mentioned Gearhardt, who directs U-M’s Meals and Dependancy Science and Remedy lab.
“Once we realized tobacco merchandise have been addictive, it made us notice that smoking wasn’t simply an grownup alternative, however that folks have been getting hooked and couldn’t cease even once they actually needed to. This similar factor seems to be taking place with extremely processed meals and that is notably regarding as a result of youngsters are a serious goal of promoting for these merchandise.”
Poor diets dominated by extremely processed meals now contribute to preventable deaths on par with cigarettes. Much like tobacco merchandise, the meals trade designs their extremely processed meals to be intensely rewarding and arduous to withstand, the researchers mentioned.
“It’s time to cease interested by extremely processed meals simply as meals, however as an alternative as extremely refined substances that may be addictive,” DiFeliceantonio mentioned.

“Extremely processed meals could be thought-about addictive substances based mostly on established scientific standards” by Ashley N. Gearhardt et al. Dependancy
Extremely processed meals could be thought-about addictive substances based mostly on established scientific standards
There’s rising proof that an addictive-eating phenotype might exist. There’s vital debate relating to whether or not extremely processed meals (HPFs; meals with refined carbohydrates and/or added fat) are addictive. The dearth of scientifically grounded standards to guage the addictive nature of HPFs has hindered the decision of this debate.
The newest scientific debate relating to a substance’s addictive potential centered round tobacco. In 1988, the Surgeon Common issued a report figuring out tobacco merchandise as addictive based mostly on three main scientific standards: their capacity to (1) trigger extremely managed or compulsive use, (2) trigger psychoactive (i.e. mood-altering) results by way of their impact on the mind and (3) reinforce habits. Scientific advances have now recognized the flexibility of tobacco merchandise to (4) set off sturdy urges or craving as one other vital indicator of addictive potential. Right here, we suggest that these 4 standards present scientifically legitimate benchmarks that can be utilized to guage the addictiveness of HPFs. Then, we overview the proof relating to whether or not HPFs meet every criterion. Lastly, we think about the implications of labeling HPFs as addictive.
Extremely processed meals (HPFs) can meet the factors to be labeled as addictive substances utilizing the requirements set for tobacco merchandise. The addictive potential of HPFs could also be a key issue contributing to the excessive public well being prices related to a meals atmosphere dominated by low-cost, accessible and closely marketed HPFs.
