What this trial studies

This clinical study investigates how functional foods influence postprandial glucose levels and gut microbiota in adults aged 18 to 60. Over a 42-day period, participants will undergo three phases: 14 days without intervention, 14 days with functional food supplementation, and another 14 days without intervention. Continuous glucose monitoring will track glucose levels every 15 minutes, while changes in gut microbiota and urine metabolites will also be assessed. The goal is to understand how these interventions can modify glycemic responses.

Who should consider this trial

Good fit: Ideal candidates are healthy adults aged 18 to 60 who do not have diabetes or other metabolic disorders.

Not a fit: Patients with diabetes, high blood pressure, or significant gastrointestinal diseases are unlikely to benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide insights into dietary strategies for managing blood sugar levels and improving gut health.

How similar studies have performed: Other studies have shown promising results in using dietary interventions to manage postprandial glucose levels, suggesting this approach may be effective.
