I know you meant chewing not eating! Anyway, I found this info and also a gum called Zapp (google it) supposed to be better.
"LONDON (Reuters) - Consuming too much sorbitol, a sweetener widely used in "sugar-free" chewing gum and sweets, can cause serious bowel problems, German doctors said on Friday.
The warning follows the cases of two patients who suffered chronic diarrhea, abdominal pain and severe weight loss after ingesting large amounts of sorbitol.
Writing in the British Medical Journal, the doctors from Berlin said the patients -- a man and a woman -- had consumed some 15 to 20 sticks of chewing gum a day. When they kicked the habit, both regained normal bowel function.
Sorbitol, also known as E420, is poorly absorbed by the small intestine and is known to have laxative properties. But Dr Juergen Bauditz and colleagues of the University of Berlin said many consumers might fail to link it with their gastrointestinal problems.
"Our cases demonstrate that sorbitol consumption can cause not only chronic diarrhea and functional bowel complaints but also considerable unintended weight loss -- about 20 percent of usual body weight," they wrote."
