11.Although they are an inexpensive supplier of vitamins,minerals,and high-quality protein,eggs also contain a high level of blood cholesterol(胆固醇),one of the major causes of heart disease.One egg yolk,in fact,contains a little more than two-thirds of the suggested daily cholesterol limit.
    This knowledge has caused egg sales to drop 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 egg substitutes are not real eggs,but they look somewhat like eggs when they are cooked.They have the advantage of having lower cholesterol rates,and they can be scrambled or used in baking.One disadvantage,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,flax,and rice bran.In spite of their diets,however,these hens produce eggs that contain  the same amount of cholesterol as regular eggs.Yet,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 described unfairly.They use scientific studies to back up their claim.And  in tact  studies on the relationship between eggs and human cholesterol levels have brought mixed results.It may be that it is not the type of egg that is the main determinant of cholesterol but the person who is eating the eggs.Some people may be more sensitive to cholesterol 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 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.
