Imagine eating everything delicious you want -- with none of the fat. That would be great, wouldn’t it
New "fake fat" products appeared on store shelves in the United States recently, but not everyone is happy about it. Makers of the products, which contain a compound called olestra, say food manufacturers can now eliminate fat from certain foods. Critics, however, say the new compound can rob the body of essential vitamins and nutrients (营养物) and can also cause unpleasant side effects in some people. So it’s up to consumers to decide whether the new fat-free products taste good enough to keep eating. Chemists discovered olestra in the late 1960s, when they were searching for a fat that could be digested by infants more easily. Instead of finding the desired fat, the researchers created a fat that can’t be digested at all.
Normally, special chemicals in the intestines (肠) "grab" molecules of regular fat and break them down so
A. contains plenty of nutrients

D. makes foods easily digestible
