Diet, Food and Nutrition Clinical Trial
Official title:
Precision Nutrition - Impacts of Durian Consumption on Human Microbiome and Metabolome in Healthy Staff Volunteers From SingHealth
This clinical study investigates the impacts of daily durian consumption on gut microbiota, gut microbial metabolites, and host metabolome in healthy individuals.
Participants will go through an initial washout maintaining a low-fiber diet for 14 days. After washout, participants will be instructed to consume 100 grams of durian pulp every day following their breakfast or dinner for 1 week. Participants will then continue to consume 200 grams of durian pulp every day during the 2nd week of intervention and then will go through another washout for 2 weeks. During the intervention period, participants will be informed to maintain low-fiber diet. All participants will be required to note down their stool consistency and stool frequency and 3-days dietary records. Stool and blood samples will be collected at 4 time points during the study period (baseline, 1-week of intervention, 2-weeks of intervention and 2-weeks washout) and will be stored at -80 °C until analysis. The first outcomes of this study will provide insights into the interplay between durian consumption, gut microbiome, and host metabolome, as well as whether durian consumption can improve the clinical parameters (plasma glucose levels, lipid profiles and HbA1c levels) of healthy subjects. The interplay between diets, gut microbiome, host metabolome and genetic polymorphism data in healthy population will lay the groundwork to develop the precision nutrition strategy based on our regional food. These findings have potential to improve the health and well-being of the communities in our region. ;
