Chocolate, Tea, and Coffee Are Top Sources of Polyphenols in Polish Population
Polyphenols are powerful antioxidant-like nutrients that help fight free radical damage and excess inflammation in the body. A recent study found that 75% of the polyphenols consumed in Poland come from coffee, tea, and chocolate.
Participants in the study included 10,477 men and women between the ages of 45 and 69 who lived in Krakow, Poland. All of the participants completed a validated 148-item food frequency questionnaire to determine polyphenol intake.
The researchers determined that the mean intake of polyphenols was 1756.5 mg per day and that the main polyphenol groups were flavonoids at 897 mg/d and phenolic acids at 800 mg/d. They found that the Polish population consumed a total of 347 polyphenols that came from 19 polyphenol subclasses.
They also found that women younger than 50 consumed the most polyphenol-rich products.
Overall, the three highest contributors to polyphenol intake were found to be coffee, tea, and chocolate.
Researchers from the University of Catania in Italy conducted the study. It was published on February 7, 2014, in the journal Nutrition.
Previous studies have linked polyphenol intake with a variety of health benefits, including helping with weight management, fighting certain cancers, and reducing inflammation. Polyphenols can be found naturally in many foods, including honey, a variety of fruits and vegetables, red wine, chocolate, tea, certain oils and many types of grain.
