Progress 10/01/19 to 09/30/20
Outputs Target Audience:The target audience during this period is nutrition professionals, including students, faculty, and others in human health. Changes/Problems:
Nothing Reported
What opportunities for training and professional development has the project provided?Supported two Ph.D. students. How have the results been disseminated to communities of interest?Through publications and presentations in the scientific meetings. What do you plan to do during the next reporting period to accomplish the goals?Continuous working on carotenoids in the gut and how they impact mitochondrial signaling in the host cells.
Impacts What was accomplished under these goals?
Goal 1: Determine the bioavailability (absorption, distribution, metabolism, elimination) of nutrients and bioactive food components.-- We analyzed the absorption and accumulation of zeaxanthin and lycopene as bioactive carotenoids in two separate mouse feeding studies. The relevant manuscripts are under preparation for publication Goal 2: Determine the efficacy and mechanisms of action of nutrients and dietary bioactive compounds towards improved health.-- We also tested the health beneficial effect of those carotenoids and their metabolic enzyme BCO2 (beta-carotene oxygenase 2) in mitochondrial respiration and signaling, gut microbiome homeostasis shift, tight junction, and gut and systemic oxidative stress to elucidate the protective roles of carotenoids in health and inflammation. Two manuscripts were published in the period of the report.

Outputs Target Audience:The target audience during this reporting period is to students, nutrition professionals, and the public/lay person. Changes/Problems:
Nothing Reported
What opportunities for training and professional development has the project provided?During the reporting period I have communicated with my peers, had collaborations with other institutes and trainedseveral graduate students. How have the results been disseminated to communities of interest?I have done several presentations in nutrition and had related meetings while also publishing the results in scientific journals. What do you plan to do during the next reporting period to accomplish the goals?Work will continue with students, collaborators, and other peers in the proposed research. I plan to publish more papers and deliver presentations to the community.
