Dietary salt and blood vessel function

This study investigates what happens to sodium (salt) levels in the blood shortly after eating a salty meal — similar to a ham sandwich or bacon and eggs. Researchers want to know if a single high-salt meal causes a temporary rise in blood sodium and whether that rise can affect the way your blood vessels work. Participants eat a controlled meal and have their blood tested and blood vessels measured before and after.
