Food Addiction Symptoms in Adults with Alcohol Use Disorder
This study reveals that food addiction symptoms are prevalent in approximately one-third of adults with alcohol use disorder and are significantly associated with higher body mass index, greater psychological distress, and increased alcohol dependence severity, regardless of treatment-seeking status.

Imagine your brain as a high-tech command center, constantly scanning the world for rewards. Sometimes, this center gets a little too excited about specific things—like a video game character who can't stop chasing the same shiny coin. In the world of science, we call this "addiction." Usually, when people think of addiction, they picture substances like alcohol or drugs. But scientists have noticed something interesting: the same brain circuits that light up for a drink can also light up for certain foods, especially the super-delicious, sugary, and fatty ones we often call "ultra-processed foods." This idea is called "food addiction." It's not about being hungry; it's about that compulsive, "I can't stop eating this even though I know I should" feeling.
Now, imagine two major public health challenges: too much drinking and too much eating. They seem like different problems, but what if they are actually cousins? What if the same brain glitches that make someone struggle with alcohol also make them struggle with food? This is the big question researchers are asking. They want to know if people who are already dealing with alcohol use disorder (a serious condition where someone can't control their drinking) are also likely to have these "food addiction" symptoms. If the answer is yes, it could mean that treating one problem might help with the other, or that we need to look at the whole person, not just their drinking habits.
The Big Discovery: A Shared Struggle
In a recent study, a team of researchers decided to investigate this connection head-on. They looked at 743 adults who all had alcohol use disorder. To get a full picture, they didn't just look at people in hospitals trying to get sober; they also looked at people in the community who were drinking heavily but hadn't sought treatment yet. Think of it like checking two different groups of players in a video game: the ones who have asked for a "reset" (treatment-seeking) and the ones who are still playing but struggling (non-treatment-seeking).
The researchers used a special checklist called the Yale Food Addiction Scale to see if these people showed signs of food addiction. They were looking for specific symptoms, like losing control over how much you eat, craving certain foods intensely, or continuing to eat them even when it causes problems. They set the bar at having two or more of these symptoms to count as "food addiction."
What They Found
The results were pretty clear: about one-third of the people in the study (specifically, 238 out of 743, or 32.1%) showed signs of food addiction. Here is the kicker: it didn't matter if the person was in treatment or not. The rate was almost exactly the same for both groups—about 32.6% for those seeking help and 30.6% for those who weren't. This suggests that food addiction isn't just a side effect of being in a treatment program; it's a common companion to alcohol use disorder, regardless of where you are on your journey.
But the study didn't just count heads; it looked at what else was going on in the lives of these people. The researchers found that the people with food addiction symptoms were carrying a heavier load in several ways:
- Heavier Bodies: They tended to have a higher Body Mass Index (BMI), which is a measure of body weight relative to height.
- Heavier Minds: They reported more psychological distress, including higher levels of anxiety, depression, and stress.
- Heavier Drinking: They generally had more severe alcohol dependence.
Interestingly, the study found that for the people seeking treatment, food addiction was also linked to things like childhood trauma and poor sleep quality. For those not in treatment, the link was stronger with the overall severity of their alcohol problems. However, the study did not find a direct link between food addiction and how much alcohol someone drank on a daily basis, or how long they had been drinking. It seems the connection is more about the intensity of the struggle and the emotional weight, rather than just the number of drinks.
What This Means (and What It Doesn't)
The authors suggest that food addiction might be a way to spot a specific group of people with alcohol use disorder who are dealing with a more complex mix of challenges. It's like finding a hidden layer in a video game character: once you realize they have this "food addiction" trait, you understand why they might be struggling with more than just the alcohol.
The study is careful to say that this is a snapshot in time (a cross-sectional study), so we can't say for sure that food addiction causes worse alcohol problems, or vice versa. It just shows they often happen together. Also, the researchers didn't measure exactly what people ate (like how many burgers or fries they had); they measured the behavior and feelings around eating. So, while we know these symptoms are linked to higher BMI and more stress, we don't know the exact dietary habits from this data alone.
The bottom line is that for about one in three adults struggling with alcohol, there is also a struggle with food that feels like an addiction. The researchers believe that doctors and therapists should start asking about food habits just as seriously as they ask about drinking habits. By treating the whole picture—including the stress, the sleep, and the food cravings—we might be able to help these individuals feel better and recover more effectively. It's a reminder that our brains are wired to seek rewards, and sometimes, that wiring gets crossed in more than one way.
