Polyphenols may improve heart health

Earlier studies suggest polyphenols may help prevent chronic diseases, but there are few trials that measure the health effects of polyphenols in populations over time.

In this study, doctors measured total and individual polyphenols in the diets of 84,158 French adults and followed up over an eight-year study period, ending in 2017. Overall, those with higher levels of polyphenols in the diet, especially anthocyanins, catechins, and flavonols, were significantly less likely to develop heart and circulatory disease compared to those who consumed fewer polyphenols.

Anthocyanins are plant pigments that give plants their red, purple and blue color — think blueberries, cherries, cranberries, plums, or supplements like grape seed extract. Catechins are found in foods like cocoa and tea, while flavonoids are found in almost all fruits and vegetables.

Discussing the findings, doctors said, “In this large prospective study, three categories of polyphenols showed strong linear associations with a decreased risk of cardiovascular diseases: anthocyanins, catechins, and flavonols.”
