This week's lucky "winner"... Oreo cookies!!!



It's been difficult to respect fourth dimension for Food Reward Fri lately, but this calendar week I'm bringing it dorsum amongst a vengeance.  Oreos select been 1 of America's favorite cookies since their introduction inwards 1912 past times Nabisco.  They boast a tempting combination of crunchy chocolate cookie together with soft, sweetness filling.  From a nutrient vantage perspective, the combination of concentrated sugar, starch together with fatty brand them a winner.  From a nutritional perspective, these same factors brand them a loser.

Although most adults tin think of other desserts we'd rather eat, I think many of us tin recall a fourth dimension when Oreos were just virtually the pinnacle of deliciousness.  More than tasty plenty to throw a tantrum for.  It likewise helps that Oreos lend themselves to playing amongst your food.

Interestingly, Oreos were the champaign of report of a recent report on nutrient vantage inwards rats (1) that WHS reader Chris Cappuccio passed on to me.  This study, presented at the 2013 Neuroscience conference, got a lot of media attention, both positive together with negative.  What did it find?

Food vantage is the procedure past times which behaviors are reinforced past times food, together with a "rewarding" nutrient is 1 that makes you lot to a greater extent than motivated to obtain it 1 time you've eaten it a few times.  In the electrical current study, researchers used a mensurate of vantage called conditioned house preference.  Basically, they repeatedly gave rats Oreos inwards a item location, together with and therefore measured how much fourth dimension the rats afterwards spent hanging unopen to inwards that location hoping for Oreos*, fifty-fifty when the Oreos were omitted.  Crucially, the Oreos were pitted against salubrious bland rodent chow, non against an absence of food.

They establish precisely what has been shown many times before: rats LOVE human junk food.  The rats trained amongst Oreos preferred to hang unopen to the Oreo-associated location fifty-fifty when no Oreos were there, demonstrating that the Oreos are highly rewarding (i.e. Oreo consumption increased the likelihood of Oreo-seeking behavior).  Oreos are likewise highly rewarding inwards humans, otherwise they would non select sustained human Oreo-purchasing behaviors over the concluding century.

What comes side past times side is the experiment that made this report therefore controversial: they compared the vantage value of Oreos to the vantage value of cocaine together with heroin inwards their experimental model.  Intravenous cocaine or heroin was paired amongst a specific location, pitted against intravenous saline at some other location, together with the researchers afterwards measured how much fourth dimension the rats spent hanging unopen to the side paired amongst drug fifty-fifty when no drug was administered.

As expected, rats similar cocaine together with heroin, together with they spent to a greater extent than fourth dimension hanging unopen to the drug-associated location hoping for a hit.  Here's the critical finding: inwards this experiment, the vantage value of heroin together with cocaine was non significantly unlike from the vantage value of Oreos.  Also, all 3 atmospheric condition caused similar effects on neuron activity inwards the telephone commutation reward-related encephalon percentage the nucleus accumbens.  The authors destination the abstract amongst this:
These findings propose that high fat/sugar foods together with drugs of abuse trigger encephalon addictive processes to the same flat together with lend back upward to the hypothesis that maladaptive eating behaviors contributing to obesity tin survive compared to drug addiction
This is what triggered the avalanche of positive together with negative media coverage.  The negative coverage was by together with large from people who are tired of hearing the declaration that vantage together with addiction are the same thing, or that activation of encephalon regions involved inwards vantage agency something is addictive.  These people select a point, but there's a infant inwards the bathwater that nosotros shouldn't discard.

Drug addiction is basically a really potent motivation to obtain the drug, equally a resultant of the drug's high vantage value (due to straight actions on encephalon vantage circuits).  A somebody is therefore motivated to obtain a drug that she has a difficult fourth dimension controlling drug-seeking together with drug role behaviors, together with these behaviors supplant constructive behaviors similar maintaining relationships together with existence financially responsible.

Similarly, people tin survive highly motivated to obtain for sure foods (ice cream, pizza, tater chips, Oreos) due to the high vantage value of those foods.  Although calling this 'addiction' is controversial, it does Pb to the consumption of unhealthy calories inwards excess, superseding constructive behaviors similar eating an appropriate quantity of salubrious food.

The give-and-take 'addiction' triggers potent emotional reactions together with speedily leads to unproductive ground inwards the pop media.  I think the best way to think virtually this report is to discard the give-and-take 'addiction' together with just think virtually reward.  Oreos, cocaine, together with heroin all had a powerful might to motivate behaviour inwards rats.  Even though nosotros can't practise this report inwards humans, together with I dubiety humans would respect Oreos equally rewarding equally heroin, it is notwithstanding clear that Oreos together with other similar foods are highly rewarding inwards humans together with tin Pb to behaviors that undermine wellness together with other positive life outcomes.  This report is a skillful reminder of that.
