Question:
I am confused by the labels on xylitol mints and gums. The label says these are sugar free. Is this correct? I’m cutting back on carbs and want to know how xylitol is ranked on the glycemic index. – Carol
Answer:
Dear Carol, Xylitol is a sugar alcohol. Sugar alcohols are derived from monosaccharides. You might believe it is still a sugar and should be disclosed as sugar on the label. However, the FDA decided that only sugars classified as monosaccharides and disaccharides, not their derivatives, need to be disclosed as sugar on labels. Since a sugar alcohol is neither of these, then according to food labeling laws, xylitol is considered “sugar free” by the FDA. As to the glycemic index, when compared to other sugars, xylitol’s effect on blood sugar levels is extremely low. Sucrose – 68, Honey – 55, Fructose – 20, Xylitol – 8. Thank you for the interesting question.
