What is olestra l.jpg
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 l.jpg

  • 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

Concerns vitamins l.jpg
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 l.jpg
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 l.jpg
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

Procter and gamble s stance l.jpg
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 l.jpg

  • 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 l.jpg
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 l.jpg

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