EFFECTS OF STRAWBERRY CONSUMPTION ON PLASMA ANTIOXIDANT STATUS AND PARAMETERS OF RESISTANCE TO OXIDATIVE STRESS: PRELIMINARY EVIDENCE FROM HUMAN SUBJECTS

Strawberry is a relevant source of dietary antioxidants, such as vitamin C and phenolic compounds, which are widely reported to have biological properties ranging from antioxidant to anticancer and antiatherosclerotic properties.
However, the fine identification of the health-promoting phytochemicals in strawberry, and the mechanisms of action for their in vivo absorption, bioavailability and bioefficacy are still poorly understood.
In our work, a preliminary evaluation of the beneficial effects of strawberry consumption started from the observation of two groups of human volunteers, involved in a short-term and a medium-term feeding studies, respectively.
In keeping with previous findings, the plasma antioxidant capacity and the ascorbate serum concentration of the participants significantly increased during both the studies, whereas the serum urate maintained unmodified.
Relevant variations in the serum lipophilic antioxidants were also observed, and an improvement in the erythrocyte responsiveness to oxidative stress seemed to be related to the strawberry intake.
Future additional in vivo studies are strongly hoped.
