Summary

This study looked for natural markers in blood and urine that show what people have eaten, instead of relying on memory or food diaries. Thirty-two healthy adults ate carefully controlled meals, and researchers measured how their bodies processed different foods. The goal is to create a more accurate way to track diet in future health studies.
