The Effect of a Nutrient Dense Food on the Skin CarotenoidLevels of School Age Children
Completed · Not applicable
Conditions studied: Raman Spectroscopy, Children, Only
In brief
Background: In a previous study, children who consumed a high-carotenoid juice over 8 weeks significantly increased skin carotenoid levels as compared to children who consumed a placebo juice. A naturally carotenoid-rich baked product, potentially marketable as a healthy breakfast food alternative, was developed by Utah State University researchers. Objective: To determine the effect and response of a carotenoid-rich baked product on change in skin carotenoid levels among children. Design: A six week randomized controlled trial. Participants/setting: Participants were children age 5-18 during March-June, 2015 living in Cache County, UT (n=46). Intervention: Children were randomly assigned to one of two groups: treatment (n=23) with a high carotenoid baked food or control (n=25) who consumed a baked food with no carotenoids. Children were asked to eat the designated portion of the assigned food once a day for six weeks. Skin carotenoid levels were measured every two weeks by a BioPhotonic scanner and reported in Raman intensity counts. Participants were asked to maintain their diet and completed a food frequency questionnaire at Baseline, Week 3, and Week 6. Uneaten portions of the food were returned to clinic, counted, and recorded. Main outcome measures: Change in skin carotenoid levels as measured in Raman counts over 6 weeks. Statistical analysis performed: Repeated-measures ANOVA was used to assess the group differences in Raman counts.
