Explain what olestra is and how it is used and discuss its potential impact on nutrition status
Olestra (formerly called sucrose polyester) is a nonnutritive artificial fat made from sucrose and fatty acids. Olestra is a fat replacer, used to reduce the fat calories in processed foods. It is used to make some low-fat versions of snack foods, such as potato chips. Digestive enzymes cannot break its chemical bonds, so Olestra cannot be absorbed. Olestra binds fat-soluble vitamins and phytochemicals, causing their excretion; to partly prevent these losses, manufacturers saturate Olestra with vitamins A, D, E, and K. Large doses can cause digestive distress, but no serious problems are known to have occurred with normal use.
