The idea that food may be addictive was barely on scientists’ radar a decade ago. Now the field is heating up. Lab studies have found sugary drinks and fatty foods can produce addictive behavior in animals. Brain scans of obese people and compulsive eaters, meanwhile, reveal disturbances in brain reward circuits similar to those experienced by drug abusers.
Twenty-eight scientific studies and papers on food addiction have been published this year, according to a National Library of Medicine database. As the evidence expands, the science of addiction could become a game changer for the $1 trillion food and beverage industries.
If fatty foods and snacks and drinks sweetened with sugar and high fructose corn syrup are proven to be addictive, food companies may face the most drawn-out consumer safety battle since the anti-smoking movement took on the tobacco industry a generation ago.
