Starting in 1996, an FDA-mandated health warning label reads "This Product Contains<unk> .<unk>  may cause abdominal cramping and loose stools.<unk>  inhibits the absorption of some vitamins and other nutrients. Vitamins A, D, E, and K have been added". These symptoms, normally occurring only by excessive consumption in a short period of time, are known as steatorrhea and are caused by an excess of fat in stool. The FDA removed the warning requirement in 2003, as it had "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. The FDA concluded the label statement was no longer warranted". The FDA also agreed with P&G that the "label statement could be misleading and cause consumers of<unk>  to attribute serious problems to<unk>  when this was unlikely to be the case". When removing the<unk>  warning label, the FDA cited a six-week P&G study of more than 3000 people showing the<unk> -eating group experienced only a small increase in bowel movement frequency compared to the control group. The FDA concluded that "subjects eating<unk> -containing chips were no more likely to report having had loose stools, abdominal cramps, or any other GI symptom compared to subjects eating an equivalent amount of potato chips". In addition to the effects of the health warnings on public acceptance of the product,<unk>  might not have lived up to consumer expectations of speedy results. If consumers believed that they could eat more to compensate for the fat calories "saved",<unk>  would not be an effective way to improve overall diet. The manufacturers claim that the authentic taste and feel of<unk>  offsets this tendency, and some studies have shown that people who consume foods with<unk>  don't eat more to offset the loss in calories. P&G conducted publicity campaigns to highlight<unk> 's benefits, including working directly with the health-care community.<unk>  is prohibited from sale in many markets, including the European Union and Canada. Consumption of<unk>  may encourage rats to eat too much of foods containing regular fats, due to the learning of an incorrect association between fat intake and calories. Rats that were fed regular potato chips as well as chips cooked with<unk>  gained more weight when subsequently eating a high-fat diet than rats that received just regular chips.
