Current evidence supports a significant association between fruit and vegetable intake and health. In this study, we assessed the effect of consuming a vegetable-soup"gazpacho"on vitamin C and biomarkers of oxidative stress and inflammation in a healthy human population. We also examined the association between vitamin C and F(2)-isoprostanes (8-epiPGF(2alpha)), uric acid (UA), prostaglandin E(2) (PGE(2)), monocyte chemotactic protein-1 (MCP-1), and the cytokines, tumor necrosis factor-alpha (TNF-alpha), interleukin-1beta (IL-1beta), and IL-6. Gazpacho is a Mediterranean dish defined as a ready-to-use vegetable soup, containing approximately 80% crude vegetables rich in vitamin C. Subjects (6 men, 6 women) enrolled in this study consumed 500 mL/d of gazpacho corresponding to an intake of 72 mg of vitamin C. On d 1, subjects consumed the gazpacho in one dose; from d 2 until the end of the study, d 14, 250 mL was consumed in the morning and 250 mL in the afternoon. Blood was collected before drinking the soup (baseline) and on d 7 and 14. Baseline plasma vitamin C concentrations did not differ between men and women (P = 0.060). Compared with baseline, the vitamin C concentration was significantly higher on d 7 and 14 of the intervention in both men and women (P<0.05). Baseline plasma levels of UA and F(2)-isoprostanes were higher (P
