Summary

This trial aims to determine the effect of following a healthy diet on the risk of kidney stones. The researchers will test the hypothesis that a DASH-style diet can improve certain factors related to kidney stone risk

Who is the study for?

This trial is for individuals with Kidney Stone Disease (KSD) who are interested in seeing if diet changes can affect their condition. Participants will be provided all meals and must follow either a DASH-style or Western-style diet strictly for one week.

What is being tested?

The study aims to compare the effects of a healthy DASH-style diet versus a typical Western-style diet on factors in the urine that contribute to kidney stones. Participants will be randomly assigned to one of these diets, which they'll eat exclusively for the duration of the trial.

What are the potential side effects?

Since this trial involves dietary changes rather than medication, side effects may include digestive adjustments such as bloating or discomfort due to new foods introduced by the diets.
