Abstract
SANCHEZ-MORENO and others, Nutrition and Neurocognition Laboratory, Jean Mayer USDA-Human Nutrition Research Center on Aging at Tufts University, Boston, MA 02111, USA, csanchezm@if.csic.es, have studied the benefits of eating Gazpacho.
Background
Consumption of fruits and vegetables is associated with a reduced risk of death from all causes including heart disease and stroke. The aim of this study was to assess the bioavailability of vitamin C from a Mediterranean vegetable soup (gazpacho) and its influence on a variety of markers of immune function.
Methodology
Six men and six women consumed 500 ml of commercial gazpacho, constituted mainly of tomato, pepper and cucumber, per day for 14 days, corresponding to an intake of 78 mg of vitamin C per day.
Results
There were no differences in baseline plasma vitamin C concentrations between the men and women. Vitamin C concentrations were significantly higher (p < .03) on days 7 and 14 of the intervention. Baseline concentrations of uric acid and 8-epi-PGF2alpha were significantly higher (p < or = .032) in men than in women. Baseline concentrations of 8-epi-PGF2alpha decreased significantly (p < or = .05) by day 14 of the intervention. A significant inverse correlation was observed between vitamin C and 8-epi-PGF2alpha (r = -.415, p = .049). Baseline concentrations of PGF2 and MCP-1 were significantly higher (p< or = .025) in men than in women but decreased significantly (p< or = .05) by day 14 of the intervention. No effect on TNF-alpha, IL-1beta and IL-6 was observed at day 14 of the intervention.
Conclusion
Drinking a pint of gazpacho a day significantly increases plasma concentrations of vitamin C and beneficially affects immune function in healthy humans.
