I. Read the following passage, then choose the best answer.

Although they are an inexpensive supplier of vitamins, minerals, and high-quality protein, eggs also contain a

high level of blood cholesterol, one of the major causes of heart disease. One egg yolk, in fact, contain a little

more than two- thirds of suggested daily cholesterol limit. This knowledge has caused egg sales to plummet in

recent years, which in turn has brought about the development of several alternatives to eating regular eggs. One

alternative is to eat substitute eggs. These eggs substitutes are not really eggs, but they look somewhat like eggs

when they are cooked. They have advantage of having lower cholesterol rates, and they can be scrambled or used

in baking. One advantage, however, is that they are not good for frying, poaching, or boiling. A second

alternative to regular eggs is a new type of eggs, sometimes called "designer" eggs. These eggs are produced by

hens that are fed low-fat diets consisting of ingredients such as canola oil, flaw, and rice bran. In spite of their

diets, however, these hens produce eggs that contain the same amount of cholesterol as regular eggs. Yet, the

producers of these eggs claim that eating their eggs will not raise the blood cholesterol in humans.

Egg producers claim that their product has been portrayed unfairly. They cite scientific studies to back up their

claim. And, in fact, studies on the relationships between eggs and human cholesterol levels have brought mixed

results. It may be that it is not the type of eggs that is the main determinant of cholesterol but the person who is

eating the eggs . Some people may be more sensitive to cholesterol derived from food than other people. In fact,

there is evidence that certain dietary fats stimulate the body

s production of blood cholesterol. Consequently,

while it is still makes sense to limit one

s intake of eggs, even designer eggs, it seems that doing this without

regulating dietary fat will probably not help reduce the blood cholesterol level.
