Abstract
Background: Adult studies have found a strong correlation between serum carotenoids and skin carotenoids measured by resonance Raman spectroscopy (RRS). No published studies have examined correlations between skin and serum carotenoids among children. Objectives: (1) To validate skin RRS methodology against serum carotenoid measurements by high-performance liquid chromatography and (2) to determine if RRS skin carotenoids can be used as a valid biomarker of total fruit and vegetable (FV) intake
