Olestra (also known by its brand name Olean) is a fat substitute that adds no calories to products. It has been used in the preparation of otherwise high-fat foods thereby lowering or eliminating their fat content. The Food and Drug Administration (FDA) originally approved olestra for use in the US as a replacement for fats and oils in prepackaged ready-to-eat snacks in 1996, concluding that such use "meets the safety standard for food additives, reasonable certainty of no harm". In the late 2000s, olestra lost its popularity due to supposed side effects and has been largely phased out, but products containing the ingredient can still be purchased at grocery stores in some countries.

  • Olestra ist ein synthetischer Fettersatzstoff, bestehend aus Estern von Fettsäuren und Saccharose (Saccharosepolyester). Es kann nicht von den körpereigenen Lipasen abgebaut werden. Olestra wird von der menschlichen Darmflora im Wesentlichen nicht abgebaut. Da es vom Körper nicht aufgenommen und nicht verdaut wird, wird es gänzlich wieder ausgeschieden. In einer Studie des Herstellers über die Umweltverträglichkeit wird angegeben, dass Olestra in der Umwelt von Mikroorganismen mit einer Halbwertszeit von 10 bis 88 Tagen abgebaut wird. (de)

  • Olestra è un poliestere del saccarosio, prodotto per la prima volta nel 1968 dalla multinazionale statunitense Procter & Gamble. L'olestra è utilizzata come surrogato di grassi e oli nell'industria alimentare, negli Stati Uniti è anche conosciuta con il nome commerciale Olean.L'olestra è un prodotto sintetico non presente in natura: gli enzimi intestinali umani e di altri animali non sono in grado di abbattere tale molecola, che viene quindi espulsa da corpo, senza essere metabolizzata. Tale molecola è di interesse poiché il suo sapore è simile a quello dei grassi, per via delle catene lipidiche che circondano la molecola, mentre il suo contenuto calorico è nullo, non essendo assimilato dal corpo.

  • Olestra is een vetachtige chemische stof die als 'namaakolie' gebruikt kan worden. De stof kan in principe als vet worden verwerkt in eten maar wordt in de darm niet opgenomen. Olestra mag echter slechts worden gebruikt voor de bereiding van zoutjes. Hoewel niet aangetoond is dat olestra een negatief effect heeft op de in water oplosbare vitaminen B en C of medicijnen, blijkt het wel effect te hebben op de in vet oplosbare vitamine A, D, E en K en carotenoïden, die met de olestra het lichaam verlaten en dus minder worden opgenomen.

  • Olestra é uma gordura artificial não calórica cuja finalidade é proporcionar uma maior (tornar o alimento mais saboroso) sem trazer calorias, pois esta gordura não é digerida pelo organismo humano. O Olestra é um poliéster de sacarose resultado da reação de ácidos graxos e sacarose. Essa substância assemelha-se à gordura e possui propriedades físicas e organolépticas comparáveis às do triglicérides. Porém, por causa do maior tamanho de suas moléculas, não sofre a ação de enzimas lipolíticas ou das bactérias intestinais, portanto, não são nem digeridas e nem absorvidas. O Olestra é isento de colesterol, de calorias, podendo ser usado em grande variedade de alimentos, sem sofrer alterações, mesmo sob tratamento térmico, podendo assim ser utilizado no tratamento da hipercolesterolemia e hipe (pt)
