The Antioxidants Research Laboratory conducts preclinical and clinical studies on the biochemical basis and functional outcomes of antioxidant nutrients and related phytochemicals and functional foods to determine their role in health promotion and disease prevention during the aging process via modulation of oxidative stress, inflammation, glucoregulation, and microbiota.

Lab Objectives

To determine the bioavailability, pharmacokinetics, metabolism, and mechanisms of phytochemicals (e.g., carotenoids, phenolic acids, polyphenols) from fruit, nuts, vegetables, and whole grains using in vitro, animal model, and human studies.

To determine the effect of phytochemicals (e.g., alkylresorcinols, flavonoids) from fruit, nuts, vegetables, and whole grains on intermediary biomarkers of age-related conditions (e.g., cytokines, isoprostanes), metabolomics parameters (e.g., fatty acids, organic acids), physiological profiles (e.g., endothelial responses, glucose homeostasis), and functional outcomes relevant to cardiovascular disease, type 2 diabetes, and cognitive decline.

To determine the effect of phytochemicals (e.g., anthocyanins, proanthocyanidins) from fruit, nuts, vegetables, and whole grains on microbiota in the lower gut and physiological profiles (e.g., innate immunity) relevant to glucoregulation, inflammation, endothelial function, and oxidative stress.
