Imagine eating everything delicious you want - with none of the fat. That would be great, wouldnt 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 and can also cause unpleasant side effects in some people. So its up to decide whether the new fat-free products taste good enough to keep eating.
注:eliminate消除
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 cant be digested at all.
Normally, special chemicals in the intestines grab molecules of regular fat and break them down so they can be used by the body. A molecule of regular fat is made up of three molecule of substances called fatty acids.
