  1. Olestra: Is it really that bad? By Sarah Gaynor

  2. Yes.

  3. What is Olestra? Normal fats are three fatty acids bonded to a glycerol molecule. Olestra uses a sucrose (sugar) molecule joined at esters to six to eight fatty acids, instead. It tastes and feels like a fat, but our bodies don’t even know where to begin to digest it.

  4. Background • P&G wanted a fat-reducing drug in 1975 • Couldn’t show efficiency, so used as a food additive • Brand name: Olean • Approved in 1996 – Only by the US • Lay’s WOW in 1998 • Label removed in 2003 – WOW discontinued, Lay’s Light begun • Other companies dropped olestra line of chips

  5. Products • Lay's Light Original • Lay's Light KC Masterpiece BBQ • Doritos Light Nacho Cheese • Ruffles Light Original • Ruffles Light Cheddar & Sour Cream • Tostitos Light Restaurant Style • Fat-Free Pringles • Fat-Free Bar-B-Q Pringles • Fat-Free Sour Cream and Onion Pringles

  6. Concerns: Vitamins • Warning label: “This Product Contains Olestra. Olestra may cause abdominal cramping and loose stools. Olestra inhibits the absorption of some vitamins and other nutrients. Vitamins A, D, E, and K have been added.” • Vitamins A, D, E, and K are fat-soluble • Olestra carries them away • Chips fortified with vitamins

  7. Concerns: Carotenoids • Organic pigments • Found in fruits, vegetables like carrots, palm oil • May lower risk of blindness, heart disease, cancer • Like the vitamins, fat-soluble

  8. Concerns: “Abdominal cramping and loose stools” • Biggest problem • Eight-week studies (17 test subjects): • 8 g (16 chips) a day increased diarrhea by a factor of 5 • 32 g (about 3 oz of chips) gave half the subjects diarrhea • 8 g: gastrointestinal symptoms such as diarrhea, loose stools, nausea, and gas increased by 65% • 20 g was enough to double incidents • Intermittent symptoms lasted 40 days • Testimonials • http://www.zug.com/pranks/olestra/

  9. Procter and Gamble’s stance • Reduce consumption of fats • Eat as much as you want • “Olean is a replacement for fat, not for common sense.” • Gastrointestinal effects are similar to that of a high-fiber diet • “The added vitamins have no impact on the body’s vitamin levels regardless of how much or how often Olean snacks are eaten.” –Olean website

  10. Complaints • More than 20,000 complaints • More complaints after label removal, name change, removal of Olean label, too • Some consumers went to hospital • Frito-Lay being sued by Massachusetts woman • Backed by nonprofit Center for Science in the Public Interest (CSPI)

  11. Is P&G trustworthy? • Actonel, a drug for osteoperosis (Britain) • Dr Aubrey Blumsohn at Sheffield University • Ghost writer, no access to data • Finally gained access—results framed poorly and innaccurately • No action from university; suspended for talking to media

  12. Conclusion Believe what you want to believe, but I won’t be eating Lay’s Light anytime soon…
