Study Summary

This trial studies how dietary flavonoids affect the body when consumed, looking at soymilk, green tea, and blueberries.

Who is the study for?
This trial is for healthy adults aged 25-70 with a BMI of 18-30. Participants should be nonsmokers, drink less than 3-4 times per week without recent alcohol intake, and have no history of significant exposure to industrial waste. They must not have allergies to soy milk, be free from antibiotics or prescription drugs for six months, and avoid flavonoid supplements.Check my eligibility
What is being tested?
The study tests how the body processes compounds called reactive carbonyl species after taking a single dose of dietary flavonoids found in soymilk, green tea, or blueberries compared to a control group. It aims to understand the formation and movement of these compounds within the human body.See study design
What are the potential side effects?
Since this trial involves common foods like soymilk, green tea, and blueberries as interventions rather than pharmaceuticals, side effects are expected to be minimal but could include potential allergic reactions or gastrointestinal discomfort.

Study Objectives

Outcome measures can provide a clearer picture of what you can expect from a treatment.
Primary outcome measures
Change in levels of reactive carbonyl species (RCS) adducts of soymilk, green tea, or blueberry polyphenols in feces over 48 hours after one single dose of soymilk, green tea, or consumption.
Change in plasma levels of reactive carbonyl species (RCS) adducts of soymilk, green tea, or blueberry polyphenols over 24 hours after one single dose of soymilk, green tea, or consumption.
Change in urinary levels of reactive carbonyl species (RCS) adducts of soymilk, green tea, or blueberry polyphenols over 24 hours after one single dose of soymilk, green tea, or consumption.
Secondary outcome measures
Change in plasma levels of RCS over 24 hours after one single dose of soymilk, green tea, or blueberry consumption
Change in urinary levels of RCS over 24 hours after one single dose of soymilk, green tea, or blueberry consumption

Trial Design

2Treatment groups
Experimental Treatment
Placebo Group
Group I: Dietary flavonoids (soymilk, green tea, or blueberry) consumptionExperimental Treatment1 Intervention
Each subject takes breakfast with 460 ml of soymilk, green tea, or blueberry in a single dose, and samples (plasma, urine, and stool samples) at different time points were collected following the administrations of soymilk, green tea, or blueberry blend.
Group II: Control groupPlacebo Group1 Intervention
Each subject takes breakfast with 460 ml of milk or water in a single dose, and samples (plasma, urine, and stool samples) at different time points were collected following the administration of milk or water.
