Summary

This trial will study how reducing dietary salt affects blood pressure and vascular function in people who are sensitive to salt.

Who is the study for?
This trial is for men and women who typically eat more than 3400mg of sodium daily and have normal blood pressure that doesn't change much with salt intake. They must be able to consent, have a normal ECG, blood tests, not be on blood pressure meds or pregnant, not obese, and free from heart disease, cancer, diabetes or kidney issues.Check my eligibility
What is being tested?
The study aims to see how eating less salt affects the body's central hemodynamics (how the heart pumps blood) and vascular function (how the blood vessels work). Participants will follow a low-sodium diet compared to their usual high intake.See study design
What are the potential side effects?
Since this trial involves dietary changes rather than medication, side effects are minimal but may include temporary discomforts like cravings or feeling unsatisfied with less salty foods.
