Study Summary

This trial seeks to understand how people from different racial/ethnic backgrounds respond differently to diet, and how dietary guidance should be tailored to best meet each group's needs.

Who is the study for?
This trial is for healthy adults aged 18-50, not postmenopausal, with a BMI of 18.5-30 and waist size within set limits. Participants must have all grandparents from one of four major racial/ethnic groups and no lactose-free milk allergy. Excluded are those on certain medications, recent bone fractures, diabetes, cancer, liver or GI diseases, poor kidney function or smokers.Check my eligibility
What is being tested?
The study examines how Black, White, Hispanic, and Asian adults absorb calcium and excrete sodium when consuming lactose-free milk in diets with high (typical Western) versus low (recommended) salt levels. It aims to understand racial/ethnic differences in mineral metabolism related to diet.See study design
What are the potential side effects?
Since the intervention involves dietary changes only (high salt intake), side effects may include increased blood pressure or potential strain on the kidneys over time; however specific side effects will be monitored throughout the study.
