AI Article Synopsis
- Vegetables and fruits contain essential vitamins and phytochemicals that may help reduce chronic disease risk.
- The detection of these beneficial compounds at low levels in the body has been challenging due to limitations in existing measurement techniques.
- Accelerator mass spectrometry is a promising new method that allows for highly sensitive and precise measurement of specific phytochemicals, enabling better understanding of their effects when consumed in a typical diet.
Article Abstract
Vegetables and fruits provide an array of microchemicals in the form of vitamins and secondary metabolites (phytochemicals) that may lower the risk of chronic disease. Tracing these phytochemicals at physiologic concentrations has been hindered by a lack of quantitative sensitivity for chemically equivalent tracers that could be used safely in healthy people. Accelerator mass spectrometry is a relatively new technique that provides the necessary sensitivity (in attomoles) and measurement precision (<3%) towards 14C-labeled phytochemicals for detailed kinetic studies in humans at dietary levels.
