Random thought on sugar, carb & wheat "junkies"

We've all heard the stories of the alcoholic downing cough medicine, vanilla extract, mouthwashes or even other alcohols in desperation when a palatable/usual source of the ethanol they are addicted to is not around.

So I've often wondered why the "carbaholic", sugar addict, wheat addict, etc. doesn't do the same.  Addiction is often blamed for binge behavior and overeating certain foods.  They're addictive and worse yet, we have to eat. The addict must abstain completely, you would't offer alcohol to an alcoholic after all.  Etc. etc.

But I've been in desperate situations in my binge disordered life where there's been nothing binge-worthy in the house but lots of raw materials.  If it's just the carbs I so desired or were addicted to, or wheat proteins, why did I get in the car and drive however far to find a "fix" rather than eating flour from the bag?  Or mixing it with diet soda or something.  Sounds gross?  Sure, but so would some of the conconctions I once binged on in a pinch.  My point being, if one is addicted, wouldn't you want the most concentrated quick fix?  Why eat all the "fillers"?  Most hard core alcoholics I've known don't drink beer, they tend towards hard liquor with small amounts of mixer.   Same would go for sugar.  If it is the drug, why not just eat it as straight as possible rather than mix it with other stuff?

This is what leads me to seriously question the whole addiction angle of foods and the obesity epidemic.  If it were just the starch or the sugar or the bioactive veggie protein, an addict would seek out the most concentrated source.  After all, any study I've ever seen implicating foods in addiction involve large doses.  Surely if it is purely physical, our bodies would crave the concentrated source, palatability be damned.  Straight booze, especially cheap stuff, tastes pretty horrible, but if someone is jonesing for a drink and they can afford the "nip", they're not mixing it with something first.  So, if carbs and sugar etc. are as addictive as heroine (as I've seen many describe them), why don't addicts just get their fix from the plain stuff, at least in a pinch?
