	Olestra
		Olestra is a fat substitute that has the properties of a fat in flavor and texture, but is indigestible - hence a fake fat.
		Olestra is part fatty acids from cottonseed or soybean oils and part sucrose rather than glycerol in triglycerides.
		Since olestra is such a large nonpolar molecule, it may dissolve or combine with some of the fat soluble vitamins such as A, D, E, and K, and carotenoids.

	Eating olestra linked to lower cholesterol and fat intake
		Mean dietary fat intake also fell among heavy olestra consumers, from 35 percent daily calories from fat at the beginning of the study, before olestra hit the market, to 32 percent a year later.
		Olestra manufacturer Procter and Gamble Co. commissioned the study, called the Olestra Post-Marketing Surveillance Study, or OPMSS, to meet FDA requirements for post-marketing surveillance of the fat substitute, also known by the brand name Olean.
		Olestra, a synthetic fat substitute made from sucrose and fatty acids, in 1996 gained federal approval for use in savory snacks, in 1997 was test marketed at selected sites and in 1998 became available in stores nationwide.

		Olestra may make one ounce of potato chips, which used to contain 150 calories and 10 grams of fat, contain a mere 70 calories and no fat.[1] Yet, there is a cost for this elimination of fat and reduction of calories.
		Olestra may deplete the body of fat-soluble vitamins, affect the blood level of vitamin K, and be a potential cancer risk.
		Olestra is a polyester of sucrose and six or more triglycerides.[1] Although all the compounds (sugar, oleic acid, and fatty acid) which form olestra are able to be broken down by the body, the human body is not able to digest olestra.

	Olestra
		They believe that if olestra is approved by the FDA that the American public is being asked to participate in a huge uncontrolled experiment without being informed about potential risks.
		Proponents of olestra, including Proctor and Gamble and the FDA, are quick to point out that they do not believe that a minor reduction in blood serum caretenoids will lead to grave public health problems and that replacing fat with olestra will dramatically reduce the larger problem of cardiovascular disease resulting from high fat intake.
		However the public should be educated that olestra is not a panacea and certain individuals at high risk for caretenoid related diseases may want to consider alternatives or at the very least supplement their dietary caretenoids.

		The approval today means that FDA has determined that the available data and information establish that olestra is safe for use in savory snacks.
		For olestra, the safety evaluation focused not only on its toxicity, but also on the product's effects on the absorption of nutrients and on the gastrointestinal system.
		Studies of olestra indicated it may cause intestinal cramps and loose stools in some individuals.

	FDA Backgrounder: Olestra and Other Fat Substitutes
		Because olestra is formed by chemical combination of sucrose (sugar) with fatty acids, it has properties similar to those of a naturally occurring fat.
		In 1990, it amended the petition to limit olestra's use to 100 percent replacement for conventional fats in the preparation of savory snacks, such as potato chips, cheese puffs, and crackers.
		Also, the committee agreed that while olestra has no effect on water-soluble nutrients, it should be formulated to contain vitamins A, D, E, and K to avoid their depletion in people who eat olestra-containing foods.

	The New Fat Substitute Olestra: What Do I Need to Know?
		Olestra is a synthetic chemical made from vegetable oil and sugar.
		Another concern was that olestra absorbed fat-soluble vitamins from foods eaten at the same time as olestra-containing foods.
		So the FDA has required that olestra products be fortified with vitamins A, D E and K. Another group of nutrients that some people think is important are "carotenoids," which include the carrot-derived nutrient beta carotene.

	Olestra
		In this essay, Blackburn, a member of the FDA Working Group on Olestra and the FDA Food advisory Committee, rails against FDA approval of Olestra, the fat substitute that will soon be used in a number of snack foods such as potato chips.
		The essence of Blackburn's argument is the FDA did not compel Olestra's manufacturer, Procter & Gamble, to prove that the use of Olestra as a food additive poses zero risk to the American public.
		Apparently, one of Blackburn's public health concerns is that Olestra may leach certain vitamins from the body, including vitamins A, D, E, and K. At least some of the concern with this leaching is that these antioxidant vitamins are thought to play a role in preventing cancer.

	Diabetes Monitor - olestra
		Olestra (Olean™) is a synthetic oil (liquid fat) that passes through the gastrointestinal tract without being digested or absorbed.
		The U.S. FDA has decided that olestra is safe enough for consumers to decide for themselves whether to use it.
		Unless supplemental vitamins are added to it, olestra also reduced the absorption of vitamins A, D, E and K. It sometimes causes "anal leakage" with soilage of undergarments.

		The olestra molecule differs from a fat molecule in that it has six to eight fatty acids on a sucrose core, as opposed to three fatty acids on a glycerol core.
		Olestra causes diarrhea and affects the absorption of Vitamins A, D, E, and K. In essence, olestra acts like a giant sponge, taking nutrients out of the body before they have a chance to be absorbed in the intestines.
		In one study, almost one-half of the group reported having diarrhea, bloating, and gas disturbances after eating eight grams of olestra, the equivalent of less than the amount of olestra in one ounce of potato chips (http://plainfield.bypass.com/%7Etwilbur/olestra.html).

		The fat substitute Olestra, used in some popular snack foods in the USA, was rejected by a Canadian food regulatory agency, leaving the United States the only country in the world where it is allowed.
		The Washington-based not-for-profit advocacy group Center for Science in the Public Interest (CSPI) said that the decision should cause the U.S. government to rethink its 1996 approval of olestra, which is an ingredient in Frito-Lay Inc.'s "Wow!" and Procter and Gamble's "Pringles" potato chips.
		In addition to the problems mentioned above, the very use of olestra is predicated on the misconception that fat is an "evil" substance that should be avoided at all costs.

		Olestra is being officially considered by the Food and Drug Administration as a food additive, not a drug.
		There is not supposed to be any claim of benefit for food additives, and therefore the FDA application does not include an evaluation of benefit.
		There are a few other studies of fat reduction where individuals were counseled and given support and had extreme, really state-of-the-art interventions to reduce their fat intake.

	Olestra Toxicity Information Center
		Olestra (also known as olean) is the fake fat chemical sold by Proctor & Gamble (P&G) as a cooking oil.
		Since there has been absolutely no long-term research on olestra, especially independent research, eating olestra (even in small amounts) on a regular basis is a dangerous experiment.
		Further details about olestra hazards can be found on the CSPI web page.

	FDA Review of Unpublished Procter & Gamble Olestra “Fecal parameters” Study 26dec95
		The stiffness of the olestra was approximately 90 kPa/s.
		There was a steady increase in the number of diarrheal bowel movements with increasing olestra dose eaten: 5 episodes of diarrhea among subjects while eating 0 g/d olestra; 14 episodes of diarrhea among subjects whole eating 10 g/d olestra; and 40 episodes of diarrhea among subjects while eating 20 g/d olestra.
		The mean wet weight of stool for persons who consumed olestra and reported diarrhea during the fecal collection periods ([140± 36 for olestra 10 g/d] and [158±36 for olestra 20 g/d]) exceeded the mean wet weight of their stools during the placebo period (111±61), when none of the subjects reported diarrhea.

		This means that while Olestra is passing through the digestive system, not being digested and not being absorbed, it is absorbing and removing from the body these essential nutrients.
		Olestra is a fat molecule that is so large we don't nutritionally interact with it but chemically it is still very much a fat.
		It's not likely Olestra will have a significant effect on hypercholesterolemia because medical studies increasingly indicate this condition to be more a matter of heredity and less a matter of the level of dietary intake of cholesterol.

		Although the evidence against approving Procter & Gamble's Olestra was overwhelming, on January 24, 1996, the FDA gave P & G thumbs up to start manufacturing snack foods with the fat substitute.
		Olestra is synthesized from sugar and fatty acids.
		Olestra can deplete the body of fat-soluble vitamins, including A, D, E, and K, as well as carotenoids, such as beta carotene, alpha carotene, etc. Carotenoids are important antioxidants which, according to numerous studies, may help protect against cancer and heart disease.

	Frito-Lay Target of Olestra Lawsuit
		Those chips are made with olestra -- the controversial fat substitute that causes diarrhea, stomach cramps, and other unappetizing symptoms.
		She says that she would not have bought the product had she had known the chips contained olestra and is asking the court to require labels on Light chips warning consumers about the potential for adverse reactions.
		The laxative-like effects of olestra became fodder for late-night comics in the mid-1990s, but the complaints filed by people who became sick after eating olestra are not so amusing.

	FDA Changes Labeling Requirement for Olestra
		The Food and Drug Administration (FDA) today announced a change in the labeling requirement for olestra -- the zero calorie fat substitute developed by Procter & Gamble Co. (P&G) for use in certain snack foods -- because FDA has concluded the label statement is no longer warranted.
		FDA approved olestra in 1996 for use in savory snacks like potato chips, cheese puffs, and crackers.
		As part of that approval, FDA required manufacturers to add vitamins A, D, E, and K to olestra-containing foods to compensate for olestra’s effects on these fat-soluble vitamins.
