Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
This study aims to evaluate the antioxidant and anti-inflammatory effects of acute and chronic consumption of two sweet orange (Citrus sinensis) varieties-'Rosy Red Valencia', which is rich in carotenoids such as lycopene, phytoene, and phytofluene, and 'Olinda Valencia', which lacks these carotenoids-in healthy adults. In this 4-week, randomized, parallel-arm clinical trial, participants will consume either 'Rosy Red Valencia' or 'Olinda Valencia' oranges daily. The study will assess the effects of sweet orange intake on markers of oxidative stress and inflammation, plasma carotenoid concentrations, gene expression in peripheral blood mononuclear cells, and gut health. Findings from this study may help identify potential health benefits associated with specific carotenoid profiles in sweet oranges and provide insights into their role in modulating inflammation and oxidative stress.
