Summary

This study investigates how a high-salt diet versus a low-salt diet influences blood pressure and the immune system in middle-aged adults. Participants follow each diet for one week while their blood pressure and inflammatory markers are measured. The goal is to understand why some people's blood pressure is sensitive to salt and whether inflammation plays a key role.

Active substance: High salt diet and low salt diet
What this could lead to: If successful, this could lead to a simple way to identify who is salt-sensitive and inform future treatments for high blood pressure.
What could go wrong: This is an observational study, not a treatment trial. Results may not lead to immediate clinical changes, and individual responses to salt vary widely.
