Study summary

Vegetable is well known to prevent chronic disease,however, the mechanism of its nutrients and non-nutrients still remains to be discovered.We design a feeding study which provides plant foods to subjects one by another and monitoring metabolomic changes up to 7 hours.The goal of this study is to establish a protocol for documenting metabolomics response to plant foods and try to characterize plant foods in terms of their anti-hypertension potentials with metabolomic profiling information.

Interventions

  • OtherLow phytochemical diet(LPD), high phytochemical diet(HPD)

    LPD is a basal diet which low in soy,vegetable and fruit and other plant food to approach low phytochemical. HPD is the diet which add two serving test vegetable in the lunch of LPD.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on May 18, 2012, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
