hi Sandi,
Someone asked a similar question recently, and I posted my response, but I can't remember which topic to search under .. (it must be a sign that I'm posting too much, when I type in the word "insulin" authored by me, and get hundreds and hundreds of results ..
)
Anyway, after hours scouring the web, and poring over volumes of books, I could find NO direct physical link between artificial sweeteners and insulin, EXCEPT ... often, the packets and powdered sweeteners have maltodextrin and dextrose added. THESE are indeed carbs, and if eaten in excess, will result in a rise in blood sugar, and a surge of insulin (triggering more cravings). Products like diet Jello, and diet soft drinks don't contain these fillers, so are less likely to cause such a problem. On the other hand, they may contain citric and/or phosphoric acid, both of which are known to cause stall problems for SOME people. I personally enjoy these products on occasion myself, and have no problem, but I might if I drank say, a 2 liter bottle of diet pop every day. Don't know .. ??
HOWEVER, there can be an
emotional link between artificial sweeteners and insulin. In Carbohydrate Addicts, the Hellers explain how the mere sweet taste will trigger an emotional response for someone addicted or strongly craving sweets and carbs. Indulging the craving causes a release of endorphins, and a cascade of neurohormones --- serotonin, adrenaline, dopamine, among others --- in response. It's the surges of these hormones which ultimately trigger the release of insulin. It's sort of like Pavlov's dogs .... remember the experiment?, they were given food every time a little bell rang, to which they responded by salivating and drooling. Eventually, they salivated and drooled to the sound of the bell alone, without the presence of any food. A purely physiological, hormonal response to an emotional trigger.
If you feel in control of sweet cravings, rather than them controlling you, there's likely no problem whatsoever. But if you are drinking liters of pop, and eating a lot of artificially sweetened foods to fill a void in your diet, it may well be that those sweets, carb-free as they may be, are only perpetuating the addiction, and the insulin release is only serving to store body fat (since there's no carbs there for it to deal with)
Just a note too, about maltitol and sorbitol, and all the other sugar alcohols used to sweeten "sugar-free" candy and chocolate. These are NOT artificial sweeteners, they are indeed carbs, and they do cause blood sugar and insulin to rise, although much more slowly and more incompletely than ordinary sugar.
hope this helps ...
