It has been known for years that people with high blood pressure should avoid foods high in salt, since a high salt intake can worsen high blood pressure. However, it is often erroneously assumed that those not suffering from high blood pressure would not benefit from restricting their sodium intake when in fact most people would benefit greatly.

Which one of the following statements, if true, would most strengthen the claim above?

A) Many people who eat a lot of salt do have high blood pressure.( Strengthen)
B) Salt doesn't always contribute to high blood pressure.( But it may contribute)
C) A salty diet is even more likely to lead to high blood pressure when combined with smoking.( Smoking is out of discussion)
D) Even people who do not eat salty foods sometimes develop high blood pressure.(but risk of developing high blood pressure increases with increased salt intake)
E) Salt has other harmful effects in addition to contributing to high blood pressure.( Other effects are out of discussion)

Will go with option A.

Thanks
