Research has developed Olestra, a product on the market that is used as a fat alternative. What food sources contain Olestra? How does the product impact absorption of vitamins and some nutrients? What are the positive effects and the negative effects
of Olestra? One concern about Olestra and other newly developed products is that they will not reduce the actual fat content, but rather would increase it. Explain the rationale for this concern.
Olestra is approved for use only in potato chips, tortilla chips, and crackers. Olestra inhibits absorption of some vitamins and nutrients. In particular, the absorption of fat-soluble vitamins A, D, E, and K is inhibited. These vitamins have therefore been added to products containing Olestra. Olestra contains no calories, but can cause diarrhea and cramps for some consumers. Some believe that people who use the Olestra food sources will not replace their high-fat snacks with the Olestra snacks, but will simply add the Olestra snacks and will continue to also eat the fatty foods.
