Nutritionist: It is well known that eating excessive salty food often induces acute cases of high blood pressure. A recent medical research further demonstrated that people who are easily tempted by salty food are significantly more likely to have permanently high blood pressure than are people who prefer non-salty food. Considering the well-established fact that those with permanently high blood pressure are likely to have heart disease, the recent research indicates that heart disease can result from nutritional factors.

Which one of the following, if true, would most weaken the nutritionist’s argument?

A) Those who are easily tempted by salty food are less likely to recover fully from episodes of heart disease than are other people.
B) Medication designed to control high blood pressure can greatly affect the food tastes of those who use it.
C) People with permanently high blood pressure who prefer non-salty food virtually never develop heart disease.
D) Those who discover that they have heart disease tend to become more easily tempted by salty food.
E) A non-nutritional factor that causes permanently high blood pressure generally makes people prefer salty food.

E is the answer. If E is true, then the conclusion of the argument "heart disease can result from nutritional factors" won't hold since the salty food preference is caused by a non-nutritional factor.

Answer choice C kind of strengthens the link between salty food preference and heart disease. At least, based on C alone, one cannot say salty food will not cause heart disease.
