Olestra, which is found in packaged ready-to-eat foods, was produced as an alternative to products with high fat content. Olestra is used as a fat substitute without increasing the calorie value of the products. Experts warn that olestra should be avoided because it causes many health problems. Olestra was accidentally discovered by Procter and F. Mattson and R. Volpenhein in 1968.
In 1996, Olestra was approved by the Food and Drug Administration as a substitute for oils and fats, as a replacement for pre-prepared snacks. In the late 1990s, Olestra lost popularity due to side effects and its use was largely restricted. However, products containing Olestra are still sold in grocery stores in some countries.
It is known that olestra, which prevents the absorption of essential vitamins, causes obesity, prostate and lung cancer, abdominal pain, gastrointestinal problems, and vision disorders.
It is found in many packaged convenience foods such as olestra, potato chips, spicy cookies and crackers.
