2021, Nutrition, Metabolism and Cardiovascular DiseasesCitation Excerpt :24-hour urinary excretion is considered the most reliable biomarker of dietary potassium intake in adults on a population basis and a more objective indicator than dietary recall surveys that indeed depend on the memory, awareness and reliability of participants in the survey, and do not consider the incomplete dietary potassium absorption in the gut [12,27,57ā60]. However, due to partial elimination of potassium through other physiological ways such as faeces and, to a lesser extent, sweat, recovery rates of between 77% and 92% of dietary potassium in the urine have been reported in different studies [12,26,27,35,57,58,61]. According to the EFSA document on Dietary reference Values for potassium [12], we made the choice to use a conversion factor of 1.30 which was based on the ratio of potassium dietary intake to urinary excretion reported in the only two studies in which both chemical analysis of the diet and 24-h urine collection were performed [26,27].
