Summary

This study looks at how the bacteria in a pregnant woman's gut (her microbiome) and her nutrition affect her baby's growth and health. Researchers are following 800 young pregnant women (28 and under) in Toronto throughout pregnancy and for a year after birth. They collect stool, blood, and diet information to understand these connections.
