Polyphenols are naturally occurring compounds found largely in fruits, vegetables, coffee, tea, nuts, legumes and cereals. With antioxidant, anti-inflammatory and anti-carcinogenic properties, polyphenols offer many health benefits.
Researchers analyzed the effect of polyphenol-rich diets by means of nutritional biomarkers – the total urinary polyphenol (TUP) concentration– as a proxy measure of intake.
Results corroborate scientific evidence suggesting that people consuming diets rich in fruit and vegetables are at lower risk of several chronic diseases and overall mortality.
The development and use of nutritional biomarkers enabled researchers to make a more precise, and particularly, more objective estimation of polyphenol intake, as it is not only based on participants memory when answering a food frequency questionnaire.Resource: IDEAFit
