NCT07120035

Brief Summary

The purpose of this research is to see whether a finger scanning device can accurately measure carotenoids, the colorful substances in fruits and vegetables, in people's skin. Participants are being invited to take part in this research because they are over the age of 18 years, and a healthy volunteer. To be eligible, participants must be: Non-Hispanic African American/Black, Asian, non-Hispanic White, or Hispanic/Latinx; Over 18 years of age; Able to speak, read, and understand English; Willing and able to drive to the research office, have a small amount of blood drawn by a trained phlebotomist, complete a questionnaire about health, demographics, and food consumption, have height, weight, body fat, and skin tone measured, and have skin carotenoids measured using the Veggie Meter; Willing to maintain usual levels of exercise and diet; Willing to consume juice daily for the study duration, 3 weeks. The juice will be provided to participants.

Study Arms (1)

Lycopene-rich juice group

EXPERIMENTAL
Dietary Supplement: Lycopene-rich juice

Interventions

Lycopene-rich juiceDIETARY_SUPPLEMENT

We sought to deliver 8400 µg of lycopene per day, and so participants were asked to drink approximately 4 fluid ounces per day of the tomato-based, lycopene-rich juice.
