Summary
This study looked at whether natural compounds called flavonoids, found in soymilk, green tea, and blueberries, can help the body get rid of harmful reactive carbonyl species (RCS). Forty-eight healthy adults drank a single dose of one of these beverages, and researchers measured RCS levels in their urine, blood, and stool over time. The goal was to understand how these foods might protect against cell damage linked to aging and chronic disease.
