AI Article Synopsis
- Accurate quantification of dietary polyphenol intake is crucial for understanding its health effects, but existing methods like food records and composition tables are inadequate.
- The review highlights the need for biological biomarkers in blood and urine to more accurately estimate polyphenol consumption, given the complexity of the relationship between diet and these biomarkers.
- It discusses criteria for developing effective biomarkers and assesses the limited options currently available for measuring polyphenol intake.
Article Abstract
In order to establish firm evidence for the health effects of dietary polyphenol consumption, it is essential to have quantitative information regarding their dietary intake. The usefulness of the current methods, which rely mainly on the assessment of polyphenol intake using food records and food composition tables, is limited as they fail to assess total intake accurately. This review highlights the problems associated with such methods with regard to polyphenol-intake predictions. We suggest that the development of biological biomarkers, measured in both blood and urine, are essential for making accurate estimates of polyphenol intake. However, the relationship between dietary intakes and nutritional biomarkers are often highly complex. This review identifies the criteria that must be considered in the development of such biomarkers. In addition, we provide an assessment of the limited number of potential biomarkers of polyphenol intake currently available.
