Overview
Brief Summary
The purpose of this study is to perform dietary intervention studies on a variety of vegetables.
Detailed Description
Plant-based foods have always been an important component of a healthy diet. High intake of plant foods may not only maintain normal bodily functions through the provision of dietary fiber, vitamins, and minerals but also relieve symptoms and prevent diseases. Many studies have pointed out that high intake of plant foods may reduce the incidence of non-communicable disease. Past research investigating the effect of phytochemicals has usually been limited to single substances or single foods. However, a number of researchers have pointed out that phytonutrients and dietary components are likely to act synergistically.Health effects and mechanisms of phytonutrients in combination have not been carefully studied in population settings. The technology of metabolomics has enabled the simultaneous measurement of hundreds of small molecules in biological samples. Exploring the change of metabolites after feeding can not only help us understand the role of plant foods, but may also provide opportunities to assess plant food intake levels.

Outcomes
Primary Outcomes
Intensities of multiple serum metabolites
Time Frame: 11.5 hours (after lunch at 19:00PM)
The outcome measure consists of intensities of multiple serum metabolites from a liquid chromatography/time-of-flight/mass spectrometry (LC/TOF/MS) experiment. Intensity means the level of response variable (a given metabolite) showing the degree of response detected by LC/TOF/MS.
Intensities of multiple urinary metabolites
Time Frame: 8.5~11.5 hours (7-hour after lunch urine sample collected from 16:00 to 19:00PM)
The outcome measure consists of intensities of multiple urinary metabolites from a liquid chromatography/time-of-flight/mass spectrometry (LC/TOF/MS) experiment. Intensity means the level of response variable (a given metabolite) showing the degree of response detected by LC/TOF/MS.
