Summary
This study aims to find better ways to measure what people eat by looking for biomarkers in blood, urine, hair, and fat. Fifty-nine healthy men will eat carefully controlled diets with different amounts of meat, fish, and soda for 12 weeks. Researchers will then check if changes in certain natural markers match the foods eaten. The goal is to develop a more reliable tool for nutrition research.
