“Flavonoids are present in many plant-based foods and drinks including fruits, vegetables, tea, herbs and wine," Aedin Cassidy, a professor at UEA and lead researcher of the study, said in the release. "We examined six main types of commonly consumed flavonoids and found that three in particular -- anthocyanins, flavanones and flavones -- are beneficial. Men who regularly consumed foods high in these flavonoids were 10 per cent less likely to suffer erectile dysfunction. In terms of quantities, we’re talking just a few portions a week.”
According to the researchers, Americans get most of these beneficial flavonoids from from things like red wine, strawberries, apples, pears, blueberries, and citrus products. Ultimately, a combination of maintaining a flavonoid-rich diet and exercise can reduce the risk of developing ED by 21%, per the release. The study includes data from more than 50,000 middle aged men, who were asked about their ability to keep it up enough for sex and their diets since 1986.
