What this means
Kidneys often slow with age, which might change how the body handles extra phosphate from food. This study plans to test whether age and sex change that response.

Registry summary
Kidney function declines with age and this could affect phosphate balance after an acute phosphate load (increased phosphate intake). In daily life, we regularly experience acute phosphate loads through our diet.
The aim of this clinical study is to determine whether the body's response to increased phosphate intake changes with age and whether there are sex differences in this response.
