About

This cross-sectional study aims to investigate the associations between dietary intake, cardiometabolic health markers, and gut microbiota composition in Singapore adults.

Full description

Diet plays a crucial role in maintaining overall health, and changes in dietary patterns are increasingly recognized as major contributors to chronic disease development. Inadequate dietary intake and poor diet quality have been linked to increased risks of cardiometabolic diseases and disruptions in gut microbiota composition. However, most studies investigating these associations have been conducted on Western populations, and there is a lack of research focusing on Asian populations. Given the genetic, metabolic, and dietary differences between Western and Asian populations, examining these associations in an Asian population is essential for a deeper understanding of population-specific risk factors and health outcomes. Therefore, there is an urgent need to assess the associations between dietary intake, cardiometabolic health, and gut microbiota composition in Asian population.

This cross-sectional study aims to investigate the associations between dietary intake, cardiometabolic health markers, and gut microbiota composition in Singapore adults.

Findings from this study will offer valuable insights into the relationship between diet, cardiometabolic health, and the gut microbiota in this population. In addition, this research may identify specific dietary patterns or nutrients that offer greater benefit for cardiometabolic and gut health. In turn, these findings can contribute to the improvement of current dietary guidelines aimed at promoting better cardiometabolic and gut microbiota outcomes for the broader Singaporean population.
