Erhöhte Polyphenolaufnahme führt zu besserer Herzgesundheit!
Eine neue Studie zeigt, dass Menschen mit der höchsten durchschnittlichen Zufuhr von Anthocyanen ein um 14 % geringeres Risiko und ein um 22% geringeres Risiko für ischämischen Schlaganfall haben. In einer neuen Studie fanden Forscher heraus, dass durch eine Polyphenolzufuhr, z.B. in Form von Beeren (Anthocyane) und Zitrusfrüchten (Flavanone) das Risiko für vaskuläre Krankheiten enorm gesenkt werden kann.
Forscher haben nun die Daten von insgesamt 43.880 gesunden Männern dokumentiert und ausgewertet. Über einen Zeitraum von 24 Jahren stellten Forscher 4046 Herzinfarkte und 1572 Schlaganfälle fest.
Durch erhöhte Flavanone Aufnahme, kommt es zu einem geringeren Risiko einen ischämischen Schlaganfall zu erleiden.

Habitual intake of anthocyanins and flavanones and risk of cardiovascular disease in men.
Although increased fruit intake reduces cardiovascular disease (CVD) risk, which fruits are most beneficial and what key constituents are responsible are unclear. Habitual intakes of flavonoids, specifically anthocyanins and flavanones, in which >90% of habitual intake is derived from fruit, are associated with decreased CVD risk in women, but associations in men are largely unknown.
During 24 y of follow-up, 4046 myocardial infarction (MI) and 1572 stroke cases were confirmed by medical records. Although higher anthocyanin intake was not associated with total or fatal MI risk, after multivariate adjustment an inverse association with nonfatal MI was observed (HR: 0.87; 95% CI: 0.75, 1.00; P = 0.04; P-trend = 0.098); this association was stronger in normotensive participants (HR: 0.81; 95% CI: 0.69, 0.96; P-interaction = 0.03). Anthocyanin intake was not associated with stroke risk. Although flavanone intake was not associated with MI or total stroke risk, higher intake was associated with a lower risk of ischemic stroke (HR: 0.78; 95% CI: 0.62, 0.97; P = 0.03, P-trend = 0.059), with the greatest magnitude in participants aged ≥65 y (P-interaction = 0.04).
Higher intakes of fruit-based flavonoids were associated with a lower risk of nonfatal MI and ischemic stroke in men. Mechanistic studies and clinical trials are needed to unravel the differential benefits of anthocyanin- and flavanone-rich foods on cardiovascular health.
