 The study found four distinct groups of people based on their diets. Group one had higher levels of T-polyphenols, group two had higher levels of wine polyphenols, group three had higher levels of flavonones and flavons, which are found in fruits and vegetables, and group four had higher levels of hydroxycinamic acids, which are found in coffee and chocolate. This shows that different types of polyphenols can be found in various foods, and that consuming a variety of foods can help provide a balanced diet.
