The Eating Compulsion: Refined Food Addiction

Food addiction isn't a joke, and it might shed new light on how to solve the world's obesity problem. Learn more about the relationships between refined foods and our brains.

We're all familiar with the "fast food will kill you, don't you dare touch that doughnut, put down the chips or your mother gets it" health mantras sung by fitness and nutrition experts. Those of us who are determined to follow a fit lifestyle find these nutrition "don'ts" simple, although sometimes difficult to follow. Often, we choose to "just say no." For some, "saying no" might not be an option.

According to new research that brings together psychology, physiology, and nutrition, food addiction may be a real thing. Studies that show how food affects addiction centers in the brain are rare and inconclusive, but good evidence suggests refined sugar, refined carbohydrates, and added fat, salt, and caffeine are addictive substances. For people who are addicted to refined foods, shaking their heads at a cookie jar full of Oreos isn't just difficult—it's impossible.

Actual food addiction, although at this stage still a hypothesis, may explain why people are repeatedly unsuccessful in their attempts to lose weight, or why they re-gain weight after working so hard to lose it. This evidence suggests that helping people solve their weight issues should include psychological therapy, along with an education in proper nutrition and activity.1

The Science of Addiction

Although it's no scientific certainty, several studies have located pathways in the brain that are activated by hyper-palatable food similarly to the way key reward pathways are triggered by drug or alcohol abuse.2,1,3,5,6 These studies found similarities in the down-regulation of dopamine receptors in obese people and meth abusers. Dopamine receptors mediate pleasure, so if the brain isn't getting the same kind of pleasure from a normal amount of drug use, the user needs more to feel good.3

In the possible case of food addiction, people with down-regulated dopamine receptors need more food to feel pleasure.9 Furthermore, a 2011 study found those with a higher BMI had smaller dopamine receptor density.

A 1999 study found that the brains of food addicts reacted to pictures of chocolate milkshakes in much the same way the brains of recovering cocaine addicts reacted to videos of someone smoking crack.7 Clearly, our brains have a more complex relationship with food than just that of energy provider and user.

What makes food addiction even more frightening is that, if you do need a toke, there's no need to hunt down a back-alley dealer for your fix. You can buy doughnuts or hot Cheetos and Takis anywhere—and you can buy them cheap.

Refined for Your Pleasure

It's the refining process makes food addictive.1 Sure, sugar and caffeine occur in nature—you can't eat a peach without also eating 13 grams of sugar. However, natural foods have much smaller concentrations of sugar, caffeine, fat, and salt than those that have been made in a laboratory. Much like refining cocaine from coca leaves, ethanol from grains, and opiates from poppies, natural substances are not addictive until they're extracted, concentrated, and added to food. Research says our brains are hard-wired to eat carbohydrate-rich food. Constantly consuming foods that have unnatural combinations and concentrations of carbs, fat, salt, sugar, and man-made chemicals may indeed turn us into junkies.

Other studies found that repeated overconsumption of refined foods may produce long term neuroadaptations in brain reward and stress pathways. These adaptations ultimately promote depressive or anxious responses when sugary noshes aren't available.8 Brain imaging has shown that high-sugar, high-fat foods work just like heroin, opium, or morphine on the brain. That means that the food we eat directly influences how our brain works. And just like alcohol or drugs, over-indulgence cements neurological pathways that connect the intake of food to obsession. If that's not creepy, I don't know what is.

You Are Your Environment

Craving Doritos does not necessarily mean your body needs carbs, or even that it's hungry. According to research, your environment can trigger food cravings.10,11 Just as a cured drug addict may relapse when he goes back to his old friends and hangouts, so can food cravings attack when we're in a specific place or feeling a certain way.12 Part of the reason we grow addicted is that our brains like to make connections. If we usually eat a hotdog at noon, our hotdog needs become paramount midday, every day. If we consistently eat dessert after dinner, it's likely that even if you're completely sated, you'll crave a bowl of ice cream.

This learning mechanism presents an interesting piece to the puzzle of food addiction. Perhaps our cravings are acquired responses: our environments and lifestyles influence the way our brains function. It's not that your body needs popcorn; it's the darkened theater, the smell, and the tradition that makes you buy it. Couple this with the actual chemical response that the extra salt and butter provokes in our brains, and we have an eating pattern that's difficult to smash.

Breaking the Habit

Even if you're not in the practice of lurking on street corners in hopes that someone will drop a half-eaten eclair into the garbage, you may have some unhealthy habits that revolve around food. These habit-breaking tips may help you avoid your daily ritual of walking to the vending machine for Funyuns and a Coke.

1 /// Create New Habits

Charles Duhigg, author of The Power of Habit, explains that your brain actually likes habits because they're efficient; your brain doesn't have to think so much.13 So, if you want to break a habit, give your brain a new one. That doesn't mean switch Snickers for Twix, but rather create what Duhigg calls a "cue, routine, and reward system." As soon as that afternoon craving for cookies hits, go for a walk, or head to the water cooler for some office gossip. Change the loop. With enough conscious effort, your brain will start to cue your new habit automatically—that means less thinking and less stress for you.

2 /// Write It Down

If you're serious about breaking your habit, write down why you want to. Janet L. Wolfe, a clinical psychologist and author, says that writing down the antecedents and the emotions of your habit can help make it more conscious14. If you eat emotionally, write down what you're eating and what you're feeling before and after you eat it. What craving is driving your routine? Making yourself aware of the reasons behind your addiction can help you push past it.

Write it down

3 /// Reward Yourself

Choose a small goal. Every time you reach that goal, reward yourself. For example, if your small goal is to go an entire work week without hitting the vending machine, and you make it, reward yourself with a movie, bath, bike ride, or leave work an hour early on Friday. Healthy rewards make for healthy habits.

Honestly, I find when I eat a lot of vegetables and drink a lot of water, I don't ever get cravings for stuff like that. It just doesn't look appetizing; if it were put in front of me, I'd say no.

I read the Power of Habit book a little while back, really interesting/good read! You guys should check it out. Great article also! I've definitely (now that I'm in college, and their dinning hall is "all you can eat") always craving foods like pizza or grilled cheese, and I always need a couple cookies as a desert to "wash down" everything haha gotta stop that!
