The colonies of microbes living on and in our bodies make up what is called our microbiome. The bacteria outnumber our own body cells by a ratio of ten to one. Your body is host to 100 trillion bacteria of at least 10,000 different species. Before you start to worry about that, most of the bacteria will not hurt you. More than that, you couldn’t live without a healthy microbiome.
Some bacteria are essential to make our immune system work to prevent infection. Others make it possible for us to digest the food we eat. Bacteria are on our skin, in our lungs, in our mouths, especially in our gut. Your digestive system needs a good balance of bacteria for proper digestion. Some medical experts think that an imbalance of gut flora (bacteria) leads to irritable bowel syndrome and Crohn’s disease.
There has been a boom in sales of probiotics in pills, liquids, and yogurts in recent years. These contain bacteria that may help your digestive system, but the amounts and types of bacteria may not necessarily be the ones needed for your system. Everyone has a somewhat different microbiome, and, as we recently posted, it all starts in our mother’s womb. Breastfeeding further adds beneficial bacteria to the baby’s flora.
When we take antibiotics, we can kill some beneficial bacteria resulting in digestive and other health problems. Science is trying to determine what is required for a healthy microbiome so that doctors can treat various issues that many times come from our poor choices regarding our health and diet. God designed a system that works, and we are just beginning to recognize that and learn how to take care of it.
