Summary

This study is designed to compare the effect of sources of potassium on uptake and the effect of potassium on blood pressure.

Detailed description

The study will compare uptake of potassium from three different doses and sources; supplements (720, 1440 and 2160 mg) potatoes (720, 1440 and 2160 mg) or French fries (2160 mg). During 9 phases, participants will consume a controlled diet with the supplements, potato or french fries (every other week for 5 days). On the 4th day, blood and urine samples will be taken to monitor potassium uptake and excretion. Measures of blood pressure will be analyzed at defined time points throughout the intervention.

Conditions

• Potassium Bioavailability
• Blood Pressure
