Salatrim is a food additive used as a reduced-calorie fat replacer. It is an acronym of the description of this family of molecules: “Short and long chain acyl tryglyceride molecule”. Different types of salatrim exist, depending on what short chain fatty acids are used in its structure. The caloric value of salatrim varies between 5 and 6 calories per gram, versus 9 per gram of traditional fats.
The short and long chain fatty acids in salatrims are processed by the body without toxicological concerns. The long-chain stearic acid, however, is poorly absorbed which may lead to gastrointestinal distress with significant intake. Up to 30g/1oz a day is well tolerated. Studies report salatrim to produce a greater sensation of fullness compared to traditional fat.
Tolerance levels have not been firmly established, its use in the diets of children and pregnant or breastfeeding women is discouraged due to lack of research.
