Dietary Assessment by DNA Metabarcoding

Dietary assessment is an essential component of human microbiota studies. Existing methods of dietary assessment require study respondents to recall or record their food intake, rendering them time-intensive and prone to subjectivity and bias. To circumvent these survey-related limitations, the David Lab is examining whether human stool can reveal consumed foods and capture dietary patterns. We are adapting experimental and bioinformatic protocols in order to infer people’s diets without survey.
