Olestra
Olestra
Olestra (pronounced /oʊˈlɛstrə/) is a fat substitute that adds no fat, calories, or cholesterol to products. It has been used in the preparation of traditionally high-fat foods such as potato chips, thereby lowering or eliminating their fat content. The Food and Drug Administration (FDA) originally approved olestra for use as a replacement for fats and oils in pre-packaged ready-to-eat snacks in 1996.
Etymology
The term "Olestra" is derived from the words "oleo" (Latin for oil) and "ester" (a compound formed from an acid and an alcohol with the elimination of a molecule of water).

Usage
Olestra is used as a food additive, specifically as a non-caloric fat substitute. It is used in the production of certain processed foods, particularly snacks such as potato chips. It is known for its ability to provide the taste and texture of fat without contributing calories or negatively affecting cholesterol levels.
Health Effects
While Olestra can help reduce the intake of calories and fats, it can also prevent the body from absorbing certain essential vitamins such as Vitamin A, Vitamin D, Vitamin E, and Vitamin K. To counteract this, products made with Olestra are often fortified with these vitamins.
Controversy
Despite its benefits, Olestra has been the subject of controversy due to potential gastrointestinal side effects. Some people may experience adverse reactions such as abdominal cramping and loose stools after consuming products made with Olestra.
