Gut Health and Immunity The Surprising Connection

Most people think the gut is just about digestion. But did you know that over 70% of your immune system lives in your gut? The connection between gut health and immunity is one of the most powerful and underestimated aspects of wellness. According to this NIH article, the gut microbiome plays a vital role in how your body fights off illness and inflammation.

This can lead to autoimmune issues, allergies, or frequent infections. Learn more from Healthline’s full guide.

When your gut microbiome is balanced, your body is better at fighting viruses and reducing chronic inflammation. Check out this detailed piece by Medical News Today.
