Study Summary

This study evaluates the effect of phosphorus supplementation on the human metabolome. The investigators will do so by conducting a cross-over study in healthy adults consuming a study diet (normal diet supplemented by neutral sodium phosphorus, 1 gram/day) for seven days and a control diet (normal diet supplemented by sodium and potassium chloride only) for seven days with a 28 day wash-out period in between. Untargeted metabolomic analyses will be done in serum samples obtained at the end of each diet period.

Primary Outcome

Untargeted metabolomics will be the primary endpoint and will be performed on serum samples obtained for all participants at the end of each dietary period.

Interventions

  • OTHER Control Diet
  • OTHER Phosphorus-supplemented study diet
