Comparing salt versus potassium education for healthier blood vessels
This study compares two education programs — one focused on lowering sodium (salt) and one on boosting potassium — to see which improves blood vessel health. It's for people who eat a lot of salt but not enough potassium, and who generally have a healthy heart and kidneys.
