Gut Puzzle Study
Join us for a short study we are calling Gut Puzzle!
The question we aim to answer is: Do our stool bacteria help predict how we metabolize different foods?
‘Metabolize’ refers to the vast network of reactions that change the food we eat into energy we can use, and into biomass (as in… the physical ‘stuff’ of our bodies, muscle, bone, etc.) In the gut, this metabolism is driven by the bacteria. We still do not fully understand how bacterial and human metabolism work together to determine how we respond to specific foods.
About the Study
This short research study takes only 4 days to complete. We give participants a food record booklet to keep track of everything eaten for 3 days. On the fourth day participants collect stool with a kit we provide, and come for a fasting blood draw at the Fred Hutch in South Lake Union.
