Perhaps the increase in total antioxidant capacity in plasma occurring after consumption of strawberries and kiwi (Fig. 6) is also a result of the prevalence of resveratrol [29].
Red grapes also have a strong effect on plasma antioxidant status. Studies have shown that fruits consumed in quantities of 280 g cause a significant increase in TAC related to the presence of hydrophilic antioxidants (Fig. 6) as soon as 30 min after consumption. Studies also have confirmed that the main compound responsible for the plasma TAC increase is primarily resveratrol, as well as anthocyanins, proanthocyanidins, and flavan-3-ols and catechins [26].
