olestra

(ō-lĕs′trə)
n.
A calorie-free fat substitute synthesized from sucrose and vegetable oil for use in snacks such as potato chips, and capable of passing through the body without being digested.

Olestra

a trade name for a synthetic fat substitute derived from sucrose and eight acids of vegetable oils. Olestra adds no calories or fats to the food into which it is incorporated. Because the molecules of Olestra are larger and more tightly packed than those of ordinary fats, they cannot be broken down by digestive enzymes and cannot enter the bloodstream. Adverse effects reported include cramping and loose stools in some people and inhibition of absorption of some vitamins. A newer formulation is fortified with certain fat-soluble vitamins.

Olestra

A proprietary, FDA-approved synthetic (no-calorie) fat used in savory snack foods—e.g., tortilla chips, potato chips and crackers.  Olestra has an appearance, taste and texture virtually identical to fat, but unlike most dietary fats (which are composed of three fatty acids linked to a glycerol), it is composed of sixt to eight fatty acids linked to glucose and is too large for digestion by the body’s enzymes. Olestra may reduce passive over-consumption as it flows undigested through the GI tract. A one-ounce bag of potato chips fried in olestra has 70 calories; a bag fried in regular fat has 150 calories.

olestra

A non-digestible fat substitute that was given approval by the US Food and Drug Administation (FDA) in 1996 but which does not appear to be the final solution to the obesity problem. About 20 per cent of those eating it are said to have abdominal symptoms such as cramping or diarrhoea. There is also concern that Olestra might inhibit the absorption of fat-soluble antioxidant carotenoids.
