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

Condition or disease Intervention/treatment Phase
Resonance Raman Spectroscopy for Dietary Carotenoid Intake Other: Carotenoid Depletion Other: Carotenoid Repletion Other: Natural Repletion Not Applicable

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.
