We suggest that some of the involved mechanisms might be related to interactions of endogenous iron with polyphenols absorbed from the olive oil. The polyphenols may augment the antioxidant activity of endogenous iron-binding antioxidants (2). Use of phlebotomy to achieve modest decreases in stored iron level (3) or induction of near iron deficiency (4) is associated with increased HDL cholesterol concentration. Polyphenol-rich olive oil may acutely augment ...References1. Covas MI, Nyyssönen K, Poulsen HE, Kaikkonen J, Zunft HJ, Kiesewetter H, et al.
