Kardiovaskuläre Effekte von Schokolade

Dem mäßigen Genuss dunkler Schokolade werden günstige Effekte auf kardiovaskuläre Erkrankungen zugeschrieben. Dies wird dem hohen Anteil an Polyphenolen und insbesondere Flavonoiden zugeschrieben. Die aktuelle Studienlage zum Einfluss von Kakao auf verschiedene kardiovaskuläre Risikofaktoren und Erkrankungen wird im vorliegenden Artikel dargestellt.

Kernaussagen

• Auch wenn die Studienlage aktuell uneinheitlich ist, ergeben sich Hinweise, dass ein moderater Konsum von 40–50 g dunkler Schokolade alle 1–2 Tage einen günstigen Einfluss auf verschiedene kardiovaskuläre Erkrankungen haben kann.

• Das Ausmaß der Effekte scheint von der Höhe des Kakaoanteils abzuhängen und ist in vielen Studien größer im Vergleich zu denen von Milchschokolade oder „weißer“ Schokolade.

• Die biologische Wirkung der Polyphenole, die in In-vitro-Untersuchungen zu einer Verbesserung des Endothelfunktion führten, könnte vielleicht die beobachteten kardioprotektiven Effekte in den epidemiologischen Studien miterklären.

• Dunkle Schokolade ist zu empfehlen.
