Early childhood is critical in the establishment of the human gut microbiome. The microbiome impacts many aspects of health and development. There is evidence that sugar consumption can lead to an unhealthy microbiome. An unhealthy microbiome may be associated with many diseases including allergy, asthma, IBD, obesity, neurodevelopment, metabolic disease.

What is the study's goal?

The overall objective is to study the association between free sugar intake and gut microbiome diversity and cardiometabolic risk factors in preschool-aged children. Children aged 3-5 are eligible to participate. Participation includes completing a food diary for your child and collecting one stool sample. All procedures can be completed at home.
