One egg contains a whopping 213 milligrams of cholesterol. Because of concern for blood cholesterol levels, egg consumption in the United States has fallen by almost 50 percent over the last forty years. Research has shown, however, that the body compensates for increased cholesterol intake by reducing cholesterol production in the liver. Furthermore, excretion of cholesterol in bile acids increases as more cholesterol is eaten. Therefore, anyone who wants to lower the level of cholesterol in his blood should eat more eggs. The argument above depends on which of the following assumptions? (A) Eating a large number of eggs does not have any undesirable effects on the body. (B) A low blood cholesterol level is desirable. (C) Eating more eggs is the only way to lower blood cholesterol levels. (D) The body will compensate for cholesterol in the blood, as well as cholesterol that is ingested.
(E) Eggs are a primary source of dietary cholesterol.
