trans-Lycopene from tomato juice attenuates inflammatory biomarkers in human plasma samples: An intervention trial.

Scope: The effect of carotenoids from tomato juice (TJ) on inflammatory biomarkers was evaluated by performing a 4-week dose-response nutritional trial in a population at high cardiovascular risk.

Methods And Results: An open, prospective, randomized, cross-over, and controlled clinical trial was carried out with 28 volunteers (mean age 69.7 ± 3.

Differences in the carotenoid content of ketchups and gazpachos through HPLC/ESI(Li(+) )-MS/MS correlated with their antioxidant capacity.

Background: Carotenoids are important antioxidant compounds in the human diet. Owing to their constrained polyene structure, carotenoids can exist in cis and trans isomeric forms that can be difficult to differentiate in natural samples. In ketchups and gazpachos, all-trans isomeric forms are predominant.
