Why you can eat Oreo cookies without worrying about becoming addicted

oreos
One could just as easily have concluded from the Oreo-study findings that cocaine is less addictive than Oreo cookies.

A couple of people have asked me why I didn’t write about the Oreos-can-be-as-addictive-as-cocaine study that made headlines around the world earlier this week.

Well, I had three good reasons — ones I hope all Second Opinion readers will also consider when trying to evaluate the merits and limitations of any health-related study touted in the media:

1. The study hasn’t been published. Its details haven’t even been released to the public, except in a press release.

Because it’s unpublished, the study has yet to undergo peer review — a process designed to identify problems in a study’s methodology or statistical analysis that might render its findings problematic or irrelevant. All too often, unpublished studies presented at medical conferences (as this one will be next month) never find their way into a professional journal, and usually for a good reason (Peer review has its own limitations, but in most cases it’s better than no review.)

Also, I don’t generally report on research findings unless I can read the full study — including the methodology section — myself. As the saying goes, the devil is in the details.

A press release won’t do.

2. The study involved rats. Although rats (and mice) serve as important animal models for researchers, they’re not biological substitutes for humans. Time and again, research findings deemed extremely promising in rats do not pan out in humans.

One cancer researcher told me last year, not without significant frustration, that he could cure mice in his lab with a particular treatment approach, but not people.

“Over 90 percent of the stuff that works in mice,” he said, “doesn’t work in people.”

For this reason, although I read and follow what’s being done in animal research with great interest, I don’t normally report on it.

3. The findings are kind of meaningless.

This study reported that eating Oreo cookies appeared to activate more neurons in the rats’ nucleus accumben, the brain’s “pleasure center,” than exposure to cocaine. But what exactly does that mean, if anything?

As British psychologist, researcher and writer Vaughan Bell notes, the concept that something is “as addictive as cocaine” doesn’t make a whole lot of sense.

“Even among drugs, cocaine has a unique chemical profile and social context that are the main things that determine its ‘addictiveness,’ ” he writes.

One could just as easily have concluded from the Oreo-study findings, Bell adds, that cocaine is less addictive than Oreo cookies.

Yet claims continue to be made that a particular food or behavior (or just about anything having to do with computers) is “as addictive as cocaine” on the grounds that it triggers a spurt of neural activity in the nucleus accumben.

Here’s Bell’s compilation, which he posted last year on his blog MindHacks, of a few of the other addictive-as-cocaine-items that have been reported recently in the popular press: World of Warcraft, power, nicotine, junk food, high-fructose corn syrup, ice cream, cannabis, love, gambling, fatty foods, porn, Facebook, sugar, cupcakes, running.

Bottom line?

There are many reasons you may want to avoid eating Oreo cookies, especially the fact that they contain both sugar and high fructose corn syrup.

But should you avoid them because they may become addictive?

Nah. But if you have a pet rat, I’d keep the cookies away from its cage.

    Thanks for this

    Excellent article. I knew as soon as I saw the headline that the mainstream media would run with it, and people would just eat it up (so to speak). Thanks for this good, critical look at the issue.

    free advertising for Oreos

    Thanks, Susan. I was wondering why this story was all over the news the other night, and what the big deal was. As you say, the findings are meaningless. I conclude that the press release was part of an Oreos marketing campaign for their new Halloween candy corn Oreos. I bought two packages. They’re yummy!

    Thanks for laying out your hesitation

    Excellent comments all the way around. Thanks. Now I feel free to have an Oreo for lunch. Or a rat.

    Good points!

    As those of us who have worked with rats have known for years, rats have a notoriously sweet tooth.

    Also, technically cocaine is not addictive.
    It produces psychological dependence (habit formation), but not physiological dependence in the sense of opiates.
    One does not get the DT’s from cocaine deprivation, much less die from withdrawal.

    Technically, it’s a powerful reinforcer, like sugar or artificial sweeteners, which have similar effects on the nucleus accumbens.

    A reminder

    …that among my favorite blues tunes is one by Lonnie Mack and Stevie Ray Vaughn titled “Oreo Cookie Blues.” I’ve never cared much for Oreos, but the song sure makes them *seem* addictive.

    No concern for the fat?

    Your bottom line only mention the sugars.

    Years ago, Nabisco eliminated the lard, and about ten years ago, they took out the trans fats. What is left to be addicted to?

    BTW, Oreo is a Greek word meaning beautiful. A marketing exaggeration or a lie?
