A new study shows salty foods can harm your heart in just 30 minutes.

Researchers say that salty foods quickly impair the ability of blood vessels to widen, even in people with normal blood pressure.

They say the long term effects of this kind of impairment aren't yet known, but the findings suggest salt has an impact even on those with healthy blood pressure.
