Unformatted text preview: tor of the Centre for Science in the Public Interest (CSPI), a long -time opponent of olestra. "That will spare Canadians the gastrointestinal grief that thousands of U.S. consumers have experienced." While Health Canada is saying "no" to olestra, the U.S. Food and Drug Administration (FDA), under pressure from Procter and Gamble, is considering dropping the olestra warning notice ("may cause abdominal cramping or loose stools") from packages. FDA conducted a scientific review of several post - market studies submitted by P&G, as well as adverse event reports submitted by P&G and the Center for Science in the Public Interest. FDA concluded that the label statement was no longer warranted because: "Real - life" consumption studies of products containing olestra showed olestra caused only infrequent, mild gastrointestinal (GI) effects. In fact, a 6 - week study with more than 3,000 people showed that the group consuming olestra - containing chips experienced only a minor increase in bowel movement frequency compared to those people who consumed only full- fat chips. The FDA has received more than 18,000 adverse -reaction reports related to olestra (2,687 from CSPI; more than 16,000 from Procter and Gamble). That's more such reports than the FDA has received for all other food additives in history combined. Many reports describe cases of severe diarrhea, including several Canadians who ate olestra -containing products on visits to the U.S. Post - market studies showed consumers are aware of olestra and its potential GI effects. Post - market consumer studies showed that consumers were confused by the required label because they did not understand that the label meant there would be no loss of vitamins. These post - market studies also indicated that consumers erroneously believed that vitamins and minerals not affected by olestra would be lost. At a 1998 FDA Foods Advisory Committee meeting there was agreement that an asterisk- linked statement on the ingredient panel about added vitamins A, D, E, and K would be more useful to consumers. CSPI urges people who believe they suffered adverse effects as a result of eating olestra to file a report . While the current labeling requirements are effective immediately, FDA realizes and consumers can expect that there may be a period of time before companies introduce the new product label.
