Sugar-Free Sweeteners and Side Effects: A Food Scientist's View

Reports of side effects such as abdominal pain and diarrhea with high amounts of sorbitol consumption are nothing new, says Roger Clemens, DrPH, a spokesman for the Institute of Food Technologists and professor of pharmacology and pharmaceutical sciences at the University of Southern California, Los Angeles.

"The laxative effect is very well documented," Clemens tells WebMD. "It could be these individuals [in the case histories] were particularly sensitive." And they did consume excessive amounts, he notes. "We would not expect the average consumer to consume upwards of 20 sticks of gum a day."

"Sorbitol is not well absorbed," Clemens says. As a result, excess water enters the gastrointestinal tract and diarrhea can occur. Those who rely on artificially sweetened products to help manage their diabetes or to reduce overall calories, he says, should use a variety of such products and consume them in moderation. Sorbitol is found in toothpastes as well as chewing gum and sweets.
