Associations Between Dietary Intake and Cardiometabolic and Gut Microbiota Outcomes in Singapore Adults

Observational National University of Singapore · NCT06775132

This study looks at how different diets affect heart health and gut bacteria in adults in Singapore to see what eating habits might be better for their overall health.

What this trial studies

This observational study aims to explore the relationships between dietary intake, cardiometabolic health markers, and gut microbiota composition among adults in Singapore. It recognizes the significant role diet plays in chronic disease development and seeks to fill the gap in research focused on Asian populations, which have been underrepresented in previous studies. By assessing these associations, the study aims to identify specific dietary patterns or nutrients that may benefit cardiometabolic and gut health. The findings could lead to improved dietary guidelines tailored for this population.

Who should consider this trial

Good fit: Ideal candidates for this study are English-literate adults aged 21-80 years who have not made drastic dietary changes in the past year.

Not a fit: Patients taking dietary supplements or medications that affect gut microbiota or sleep outcomes may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide insights that lead to better dietary recommendations for improving cardiometabolic health and gut microbiota in Singaporean adults.

How similar studies have performed: While many studies have explored diet and health in Western populations, this study's focus on an Asian population is relatively novel and untested.
