Olestra: Is it really that bad?By Sarah Gaynor
Yes.
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.
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
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
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
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
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/
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
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)
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
Conclusion
Believe what you want to believe, but I won’t be eating Lay’s Light anytime soon…
