A comprehensive guide to understanding your gut, its influence on your health and what you can do to protect it.
The human gut is tasked with all things related to digestion, but your gut does far more than just break down food you eat. Often referred to as the "second brain," it plays a central role in maintaining health throughout the body. In constant communication with your brain, your gut influences your mood, helps regulate your immune system and helps balance your hormones. It also houses the gut microbiome, a vast community of microbes that produce essential nutrients, fight off harmful pathogens and support metabolism.

When the gut is healthy, it acts as a well-coordinated control center. But when it's out of balance, it can contribute to issues far beyond the digestive tract, including inflammatory disorders, Alzheimer's disease, skin conditions and obesity. Lifestyle factors and everyday habits, including an unhealthy diet, too little exercise, stress, certain medications and environmental pollutants, are common culprits to an unhappy gut.
