Zusammenfassung
Sekundäre Pflanzenstoffe haben gemäß präklinischen und epidemiologischen Daten interessante Eigenschaften bei der Prävention in der Onkologie. Während die Bedeutung einer gesunden Ernährung unbestritten ist, sind jedoch die epidemiologischen Daten für einzelne dieser Stoffe noch widersprüchlich. Prävention kann nicht auf einen einzelnen Pflanzenstoff oder eine Gruppe von einzelnen sekundären Pflanzenstoffen aufgebaut werden. Präklinisch liegen für alle diese Substanzen ebenfalls interessante Daten bezüglich ihrer direkten antitumoralen Wirkung vor. Sie weisen gleichzeitig aber auch auf das hohe Interaktionspotenzial hin und zeigen auch, dass die hochdosierte Einnahme von wirkungsvollen sekundären Pflanzenstoffen potenziell schädigende Wirkungen hat. Der Einsatz in Form von Nahrungsergänzungsmitteln außerhalb von klinischen Studien ist nicht empfehlenswert.
Abstract
Epidemiological data show that antitumoral plant foods are relevant for the prevention of cancer. Although nobody will deny the usefulness of a healthy diet, epidemiological data for single substances are contradictory. Prevention cannot be realized with the consumption of one or a defined mixture of some of these substances. Interesting data from preclinical experiments show that some of the identified molecules also have potential as antitumoral agents. These data also reveal a potential for interactions and, in some studies, even a possible direct negative influence in clinical use. Further controlled clinical studies are therefore mandatory.
