Consumption of an antioxidant‐rich diet is associated with a lower incidence of heart disease and is thought to be involved with preventing cancer and other inflammatory diseases. The purpose of this study was to determine the effects of twice daily consumption of dried plums as snacks for two weeks on antioxidant capacity and C‐reactive protein in humans compared to cookie consumption. Twenty‐seven women aged 25–54 years were provided with twice daily 100 kcal servings of either dried plums or low‐fat cookies for separate two‐week feeding trials with a two‐week washout period. After an overnight fast, blood samples were collected prior to initiating each feeding trial and after two weeks of each trial. Serum C‐reactive protein was measured using an ELISA assay. The Trolox‐equivalent antioxidant capacity (TEAC) assay was used to measure antioxidant capacity. Two weeks intake of 100 kcal dried plums resulted in an increase in antioxidant capacity (P<0.05) compared to two weeks intake of 100 kcal cookies. Antioxidant capacity was increased after two weeks of dried plum snack (P=0.039) but decreased with cookie snacks (P=0.018). C‐reactive protein levels did not differ significantly between the two feeding trials. These results suggest that choice of snack may impact health by influencing antioxidant status. This study was supported by the California Dried Plum Board.
