Do you know that feeling you get in your gut? It turns out your gut may really be trying to tell you something. Our microbiome – the 100 trillion bacteria and organisms living in our gut – appears to have a profound influence on our health and risk of disease. And early scientific studies show there may be a link between the microbiome and the brain that could impact the risk of Alzheimer’s and other brain diseases.
The microbiome is a collection of bacteria, viruses and fungi that live mostly in our intestinal system. They play an important role in digestion and the production of certain vitamins, and they support our immune system. Researchers around the world study the gut microbiome, especially those bacteria unique to individuals, to learn more about their influence on our overall health.
