Food manufacturers commonly use glycerin to add bulk, moisture and sweetness to food products. Glycerin is a common ingredient in products such as meal-replacement bars and low-carbohydrate foods; it adds calories to food products.
Glycerine, also known as glycerin or glycerol, is a sugar alcohol derived from fats and oils. Glycerine sweetens food products without the same effect on blood sugar levels as regular sugar, according to CVS Pharmacy's Health Resources website. Nevertheless, glycerine, like other sugar alcohols, does have some effect on blood sugar levels.
Considerations and Calorie Count
Glycerine is technically a carbohydrate, according to the U.S. Food and Drug Administration, and must be treated as such on food labels. Like other carbohydrates, glycerine contains 4 calories per gram.
Too much sugar alcohol can cause diarrhea and bloating, the Mayo Clinic cautions. You may suffer digestive problems by ingesting 50 grams or more of sugar alcohol. Check the label of food products making low-calorie or sugar-free claims, as they may contain sugar alcohol.
