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, have studied the health benefits of gazpacho soup.
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 gazpacho soup constituted mainly of tomato, pepper and cucumber, and its influence on plasma vitamin C and markers of immune function and inflammatory response.
Methodology
6 men and 6 women ate 500 ml of commercial gazpacho per day for 14 days, corresponding to an intake of 78 mg of ascorbic acid per day.
Results
There were no differences in baseline plasma vitamin C concentrations between the men and women. The maximum increase in plasma vitamin C occurred 4 h after the meal. Vitamin C concentrations were significantly higher (p < 0.03) on days 7 and 14 of the intervention. Baseline concentrations of uric acid and 8-epi-prostaglandine-F2alpha were significantly higher (p = 0.032) in men than in women. Baseline concentrations of 8-epi-prostaglandine-F2alpha decreased significantly (p = 0.05) by day 14 of the intervention. A significant inverse correlation was observed between vitamin C and 8-epi-prostaglandine-F2alpha (p = 0.049). Baseline concentrations of prostaglandine-F2 and monocyte chemotactic protein-1 were significantly higher (p = 0.025) in men than in women but decreased by day 14 of the intervention.
Conclusion
Drinking a pint of gazpacho a day significantly increases plasma concentrations of vitamin C and significantly decreases markers of inflammatory processes in healthy humans.

Comment
The above 3 research studies demonstrate the tangible clinical effects that nutrients – omega-3 fatty acids, tomato extracts and gazpacho soup can exert upon heart disease and its clinical consequences.
