The objectives of the present study is to test the impact of nutritional intervention with natural tomato juice on health among preadolescent to adolescent males. The study was coupled with quantitative measurements of selected biomarkers to validate the observed links between the regular consumption of tomato juice and impact on selected biomarkers of health status. Design of the dietary intervention trial The study consisted of 25 boys (10.5 years old), who received tomato juice for a duration of 18 days with mean daily intake of 240 g tomato juice containing 2% corn oil, which supplied 22.3 mg trans lycopene and 1.32 mg β-carotene. Blood samples were collected from the anticubital vein at 7 different time intervals according to a predetermined schedule for the analysis. Carotenoid pigments, immunoglulin E and C- reactive protein were analyzed in the plasma amples, while glutathione (GSH) was de-termined in the whole blood. The results showed that the plasma lycopene increased gradually with a peak at day 8, which was 2.55 fold in excess of the prefeeding period (day zero). The increases in the plasma concentrations of α and β -carotene reached a peak, which was 1.43 fold. The plasma immunoglobuline E (Ig E) a biomarker of allergy or the effect of infection on the immune system decreased but the level didn’t reach significant level (P>0.05). The plasma C-reactive protein levels in all children except one child were below the detection limit (< 6 mg/L), Therefore, the analysis was not repeated after the tomato feeding. With respect to blood GSH, the increases in its concentration peaked on day 14, but the increase was not significant (P>0.05). Thus, tomato juice could be considered as a potential functional product with a high antioxidant and anti-inflammatory properties but additional studies for longer period of times are warranted.
