From chocoholics and beyond, references to food cravings have been found in pop culture since the dawn of time. However, food addiction hasn’t been taken as seriously as addiction to narcotics, opiates, alcohol, and the like. Now, with new research, that just may change.
In a first of its kind study, researchers have found an intense activation of the nucleus accumbens following a meal with high-glycemic index. The randomized, blinded, crossover study, which was published in the
Interestingly, unlike previous studies of food addiction that asked participants to consume diverse foods such as cheesecake versus vegetables, this is the first study in which all participants received similar looking and tasting milkshakes, which eliminated some bias. This is also the first study to use functional MRI during the late postprandial period, which has special significance to eating behavior at the upcoming meal. Previous research with MRIs studied brain activity shortly after the meal.
Put all this together and it might mean a giant step forward in understanding food addictions as well as obesity. And that’s perfect timing, given the
That our AMA: (1) recognize obesity and overweight as a chronic medical condition (de facto disease state) and urgent public health problem; (2) recommend that providers receive appropriate financial support and payment from third-party payers, thus ensuring that providers have an incentive to manage the complex diseases associated with obesity; (3) work with third-party payers and governmental agencies to recognize obesity intervention as an essential medical service; and (4) establish a comprehensive ICD code for medical services to manage and treat obese and overweight patients.2
Based on this war cry, if obesity is a direct result of food addictions, then psychiatrists will surely be called on to join the frontlines of the fight.
Meanwhile, this study gives some hope and provides some preliminary answers. For starters, David Ludwig, MD, PhD, director of New Balance Foundation Obesity Prevention Center and study co-author, noted to the press, “
Until we have more answers, feel free to indulge in that chocolate bar.
