Resonance Raman spectroscopy (RRS) and parent report were used to assess dietary intake of fruit and vegetable (FV) consumption among young children experiencing a nutrition intervention. The nutrition intervention was "Together, We Inspire Smart Eating" (WISE). The study followed a convenience sample of low-income children in preschool (N=175) and early elementary (N=199) classrooms over an academic school year. Data were collected in a Southern, rural U.S state. Results of pre- and post-assessments indicated statistically improved consumption of FV at follow-up compared to baseline. Results were consistent using both assessment methods supporting the use of either assessment method.
