    ASSOCIATIONS OF ANTIOXIDANT CONSUMPTION FROM FOOD AND SUPPLEMENT SOURCES ON COGNITIVE FUNCTION IN OLDER ADULTS
    (North Dakota State University, 2024) Knoll, Kelly
    Oxidative stress, the imbalance of prooxidants and antioxidants, has been recognized as a possible risk factor for cognitive impairment. We postulate that increased dietary antioxidant consumption could help preserve cognitive function during aging. Dietary intake and cognitive function of 50 adults aged ≥65-years (66% women; aged 71.5±5.1 years) was assessed using Cronometer, an electronic nutrition analysis application, and the Saint Louis University Mental Status examination. The fisher’s exact test (p < 0.01) identified a significantly lower percentage of cognitive dysfunction (31.6%; 6 of 19 participants) among participants that met the Recommended Daily Allowances (RDAs) for the antioxidants, vitamin C, vitamin E, selenium, and manganese, and a higher percentage of cognitive dysfunction among those that did not meet the antioxidant RDAs (74.2%; 23 of 31 participants). However, mean cognitive scores differed insignificantly between those meeting RDAs (26.2 ±4.2 points) and those that did not (24.9 ±2.9 points; p = 0.07).
