Findings were attenuated in adjusted analyses, suggesting socioeconomic status, lifestyle, and diet quality may mediate the associations. When oxidative stress occurs at an abnormally high level, consuming antioxidants may help protect cells of the body, including brain cells, from damage, Beydoun noted. "Carotenoids, which are the pigments found in orange and yellow plants, are converted by the body into vitamin A. We found that the most important carotenoids in potentially protecting the brain may be lutein+zeaxanthin and beta-cryptoxanthin," she told  MedPage Today . "Unlike other studies, we did not analy
