Found abundantly in berries, polyphenols, an antioxidant compound, may reduce the risk of death.
Polyphenols are a type of antioxidant that is found abundantly in blueberries, raspberries, and strawberries. Cristina Andres-Lacueva, from the University of Barcelona (Spain), and colleagues analyzed data from 807 men and women, ages 65 and older, enrolled in the Invecchiare in Chianti study. Following the subjects for 12 years, the team measured total urinary polyphenols, and surveyed the subjects as to dietary habits and foods consumed. The researchers observed that the participants consuming the highest levels of dietary polyphenols were at 30% reduced risk of death. Further, those consuming polyphenol-rich foods were at lower risk of chronic diseases. The study authors submit that: “[Total urinary polyphenol] is an independent risk factor for mortality among community-dwelling older adults, suggesting that high dietary intake of polyphenols may be associated with longevity.”
