Summary

The goal of this clinical trial is to determine if a self-selected high potassium diet is easier to achieve and more effective at improving vascular health than a low sodium diet in generally healthy young adults who typically consume more than the recommended amount of sodium. The main questions it aims to answer are:

1. Is it easier for young adults to increase their potassium intake, rather than reduce their sodium intake?
2. Is a self-selected high potassium diet better at improving vascular health compared to a self-selected low sodium diet?

Researchers will compare the effectiveness of an education-based intervention centered only on increasing dietary potassium intake against an education-based intervention centered only on reducing dietary sodium intake.

Participants will be randomly assigned to receive comprehensive dietary education on adopting either a high-potassium diet or a low-sodium diet.

Education will be delivered in four weekly one-on-one sessions. Following the four-week education period, participants will be encouraged to change their diet based on what they have learned. Measures of dietary compliance (urine samples and diet records) and cardiovascular health (blood pressure, endothelial function) will be assessed at two, four, and six months post-education.

Interventions

BEHAVIORAL

High potassium dietary education/counseling

Participants assigned to this intervention arm will receive four weekly individualized education sessions on how to increase their dietary potassium intake.

BEHAVIORAL

Low sodium dietary education/counseling

Participants assigned to this intervention arm will receive four weekly individualized education sessions on how to reduce their dietary sodium intake.
