Their consumption has recently been related with the lowering of risk factors of different conditions such as cancer or cardiovascular disease. Polyphenol excretion in urine is a measure of the polyphenol intake, which is very dependent on diet, among other factors. In the present study this variable was compared between two populations: California (USA) and Barcelona (Spain). Methodology:  In order to obtain the total polyphenol content in urine, the Folin-Ciocalteau method was used after a purification by solid phase extraction. The method is based on the reduction of fosfomolibdate and fosfotungstate originated by the antioxidant capacity of the polyphenols, which can then be determined by a colorimetric measurement. Besides, creatinine in urine was also measured to get a corrected and more accurate polyphenol concentration. Data were compared using a t-test (P<0,05) of IBM SPSS Statistics software. Results and conclusions:  The comparison showed that California subjects had a significantly higher total polyphenol excretion related to that of the population from Barcelona (429,33 µg/ml vs. 274,33 µg/ml). These results could derive from a higher polyphenol intake of the population from California than that of Barcelona, but dietary data is still being analyzed.  Acknowledgements:  We would like to thank the Walnuts and Healthy Aging Study (WAHA) for providing the samples that were used in this study.
