The usual method for studying toxicity of food additives--giving upwards of 100 times the likely human intake of the substance to laboratory animals--is impractical for fat substitutes like olestra. It is not possible to feed laboratory animals the large amount of fat nutrition information substitutes that would be required to conduct a traditional toxicology test as is done with other food additives to determine safety. FDA's nutrition information Center for Food Safety and Applied Nutrition (CFSAN) is exploring these concerns in its review of a food additive petition for olestra. The manufacturer, Procter and Gamble of Cincinnati, is seeking approval to use olestra in salty or sharp-tasting snacks, such as potato chips, cheese puffs, and crackers. |

| Because olestra is formed by chemical combination of sucrose (sugar) with fatty acids, it has properties similar to those of a naturally occurring fat. But, unlike the natural products, this synthetic substitute provides safety no calories or saturated fat because it is undigestible: It passes through safety the digestive tract but is not absorbed into the body. As promising as that sounds, olestra and similar fat substitutes that may come along in the future raise new concerns: What effect can they have on the gastrointestinal system if they are not safety absorbed? Can they affect absorption of fat-soluble vitamins? Can they interfere with absorption of other nutrients or with drugs? What particular effects might they have in people with conditions that affect nutrition, such as intestinal disease? Unlike other food additives, which make up only a minute amount of the diet, fat substitutes, such as olestra, have the potential to make up a substantial portion of the diet because they replace fat, a major dietary component. |
