The microbiome is a term used to describe the trillions of bacteria that live on and in our bodies. While we used to think of these bacteria as simply "germs", we now know that they play an important role in keeping us healthy. In fact, the microbiome may even be responsible for some of the things that make us unique, like our personality or susceptibility to diseases.
So what does the microbiome do? Basically, it helps us digest food, synthesize vitamins, and fight off infection. It can also affect weight, mood, and even cognitive function. Recent studies have even shown that the microbiome may play a role in autism and other disorders.
So how can we take care of our microbiome? By eating a balanced diet, including plenty of fruits and vegetables. Also, try to avoid antibiotics (unless absolutely necessary) and other artificial chemicals which can disrupt the balance of bacteria in our gut. And lastly, exercise regularly - this helps promote healthy gut bacteria as well.
