Summary

The purpose of this study is to validate the non-invasive tool, resonance Raman spectroscopy for assessing vegetable and fruit consumption.

Detailed description

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.
