What does lactitol mean
Applications
Lactitol is used in a variety of low food energy or low fat foods. High stability makes it popular for baking. It is used in sugar-free candies, cookies (biscuits), chocolate, and ice cream. Lactitol also promotes colon health as a prebiotic. Because of poor absorption, lactitol only has 2.4 Calories (9 kilojoules) per gram, compared to 4 Calories (17 kJ) per gram for typical carbohydrates.
Lactitol is listed as an excipient in some prescription drugs, such as Adderall.
Lactitol is a laxative and is used to prevent or treat constipation, e.g., under the trade name Importal.
Lactitol in combination with Ispaghula husk is an approved combination for idiopathic constipation as a laxative and is used to prevent or treat constipation.
Safety and health
Lactitol, erythritol, sorbitol, xylitol, mannitol, and maltitol are all sugar alcohols. The United States Food and Drug Administration (FDA) classifies sugar alcohols as "generally recognized as safe" (GRAS). They are approved as food additives, and are recognized as not contributing to tooth decay or causing increases in blood glucose. Lactitol is also approved for use in foods in most countries around the world.
Like most other sugar alcohols (with the exception of erythritol), lactitol causes cramping, flatulence, and diarrhea in all individuals who consume it. This is because humans lack a suitable beta-galactosidase in the upper gastrointestinal (GI) tract, and a majority of ingested lactitol reaches the large intestine, where it then becomes fermentable to gut microbes (prebiotic) and can pull water into the gut by osmosis. Those with health conditions should consult their GP or dietician prior to consumption.
