Most of the time we think of gastrointestinal health as something to pay attention to as we age or when we start seeing problems with our health. However, more and more research is coming out showing that our gastrointestinal health starts in our development, prenatally and throughout our infancy. Babies in utero are going through a complex process as they develop their immune system. For instance, we now know that vernix, the thick, waxy substance covering a baby in the womb, is not just for protection of the skin from soaking in amniotic fluid. Vernix is now known to be part of a complex process of what we now call the microbiome.
What is the Microbiome?
The microbiome is a complex set of bacteria, fungi and protozoa that work together in human cells to build a healthy immune system and gut. We now know that vaginal birth helps aid in the process of the microbiome. Leaving vernix on baby (delaying that first bath) and breastfeeding in the first hour after birth are two ways to help build a healthy gut and immune system from the start. As a newborn receives colostrum from their first breastfeeding, baby is receiving a powerful mix of healthy bacteria in a very concentrated way. As more mature milk comes in, breastmilk changes to accommodate not only baby’s developmental needs but will also shift to protect against cold or flu the mother was exposed to as well.
What does all this mean for intestinal or (gut) health?
When a newborn receives colostrum, he or she is receiving probiotic bacteria to colonize the gut. Colostrum cannot be duplicated or supplemented in formula; it is as individual as the mother and baby. We now know that the antibodies delivered through breastmilk protect a breastfed baby well into adulthood. The recommendation is to breastfeed for at least the first year or longer if desired. Even if a newborn just receives colostrum, we know that this will still have a lifelong positive effect on not only the immune system but on gastrointestinal health as well.
