Can food truly be addictive? Is binge eating mental disorder? The two questions lead scientists to conduct many researches, but results, however, were not simple and conclusive. While some studies and researchers argue that food addiction exists and that is very similar to, for instance, drug or alcohol addiction, others strongly object to the concept of food addiction. Latest research contributed to the belief that food addiction is an addiction, and a very research-provoking one.
Researchers from the University of Georgia were focused on investigating the connection between a certain characteristic behavior and food addiction, and concluded that impulsive personality may lead to obesity.
The group, led by James MacKillop, an associate professor of psychology in UGA’s Franklin College of Arts and Sciences, were studying alcohol, nicotine and other forms of addiction earlier. They have seen a possibility to use some of the same techniques and to study the connection between obesity, food addiction and impulsivity.
A study that was published in the journal Appetite, explains the objective:
“Impulsive personality traits have been robustly associated with alcohol and drug misuse, but have received little attention in the context of food addiction. The goal of the current study was to examine the interrelationships between impulsive personality traits, food addiction, and Body Mass Index (BMI), including indirect pathways of influence.”
The study included 233 participants and used two different scales, the Yale Food Addiction Scale and UPPS-P Impulsive Behavior Scale to determine food addiction and impulsivity. The results were compared with the body mass index of each participant in order to determine the possibilities of developing obesity.
The results did show the connection between food addiction symptoms, impulsivity and BMI.
“In particular, an inclination toward behaving irrationally while experiencing negative mood states (Negative Urgency) and low levels of task persistence (lack of Perseverance) were significantly associated with food addiction directly and that relationship was responsible for their relationship to BMI.”
In conclusion, the team behind the study said:
“Monitoring food addiction symptoms early may help reduce the likelihood that compulsive food consumption patterns result in weight gain and obesity”
The groups of scientists are hoping to help physicians and other experts to improve treatments and intervention for obese people, who have a food addiction.
The study is emphasized that people with impulsive character will not necessarily develop food addiction or be obese, but the chances that an impulsive person develop the addiction to food is significantly higher, based on the results.
Obesity is a constant health treat, and it can lead to other dangerous problems such as heart disease, stroke, type 2 diabetes, and certain types of cancer. Other problems with obesity are the health care service and medical costs.
The team will continue with researching the correlation between impulsivity and obesity, with a focus on brain activities of certain individuals in situations when they think about food, to discover the link between intense craving for certain food and obesity.
