The Gut Microbiome

Your gut microbiome is made up of around 100 trillion microorganisms. If your gut health is compromised, chronic illnesses can develop. Any number of things can disrupt the gut, including medication, chronic stress, refined carbohydrates, and industrial seed oils. Find out more about the gut–body connection, and learn how to heal your microbiome and improve your health.

How Your Gut Microbiome Impacts Your Body

In a healthy gut, the trillions of microorganisms that inhabit the small and large intestine make up a symbiotic, harmonious community known as the gut microbiome. Your gut bacteria can impact everything about your health, including how your brain responds to stress, how well your body can digest certain carbohydrates, the health of your immune system, how you store fat, and much, much more. If your gut microbiome is disrupted, it can cause dysbiosis—which leads to chronic illness.
