Design outcomes

Primary

MeasureTime frame
Raise of plasma lycopene concentration in absolute (ng/ml) and relative (percentage of T0-value) after single lycopene intervention.

Secondary

MeasureTime frame
1. Optimal time point of lycopene concentration response after single dietary intervention (hours, days). 2. Influence of prior food consumption on plasma lycopene levels before and after lycopene interventions, as measured by dietary questionnaires.
