Summary

This cross-over clinical trial is being conducted to evaluate the difference in urinary messenger RNA (mRNA) biomarkers of mineralocorticoid receptor activation following a low-sodium diet, as compared to a high-sodium diet. The study team will collect urine and blood samples from each participant to study mineralocorticoid receptor-regulated mRNA biomarkers following the consumption of each diet.

The study team will instruct the participants to consume 8 days each of high- (300 mmol/day) and low- (10 mmol/day) sodium meals. The order in which the participants will eat the two study diets will be randomly determined. In between the high- and low-sodium diets, the participants will have a wash-out period of 6 days, during which they will be encouraged to consume their usual diet. Participants will be asked to provide the study team with 24-hour urine samples, random urine samples, and blood samples throughout their participation in this clinical trial.

Conditions

Interventions

OTHER

High-sodium diet 300 mmol sodium/day

Day 7 or day 21 high-sodium diet begins for 8 days. Day 15 wash-out begins for 6 days. Pre-made meals for both the high-and low-sodium diet will be provided to each participant by the study team.

OTHER

Low-sodium diet 10 mmol sodium/day

Day 7 or day 21 low-sodium diet begins for 8 days. Day 15 wash-out begins for 6 days. Pre-made meals for both the high-and low-sodium diet will be provided to each participant by the study team.
