Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This study will validate the use of resonance Raman spectroscopy to assess vegetable and fruit intake by performing a controlled feeding study during which volunteers will consume a provided diet with known amounts of carotenoids in the form of fruits and vegetables.
