Summary

This study tests whether eating more potassium can protect blood vessels from the damage caused by too much salt. Thirty healthy adults aged 55-75 will follow three different diets for 10 days each, with breaks in between. Researchers will measure blood pressure, artery stiffness, and blood vessel function to see if potassium makes a difference.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance: controlled diets varying in sodium and potassium levels
What this could lead to: If it works, this could point toward dietary guidelines that help older adults protect their blood vessels by balancing sodium and potassium intake.
What could go wrong: This is a small, early-stage study with only 30 healthy participants, so results may not apply to everyone. It tests short-term effects, not long-term health outcomes.
